2. Show HN: AI Hug – The 6th Website Built by a Newbie Developer: Author’s Latest Innovation
URL: Visit Now
Author: alexfefun
Description: ----Background----
I’m primarily a tech support guy, originally with no connection to development. But in the last couple of years, AI has advanced so rapidly that even a novice like me can leverage its power to build websites.
Due to economic pressures lately, I’ve been exploring ways to make money overseas, which is why I’m learning web development.
This site is my 6th project. Of my first 5 sites, three were built with WordPress, which didn’t really involve much development. The fourth site was made using JS, HTML, Tailwind, and Cloudflare, but as a practice exercise, I only created a simple static page.
For the fifth site, I jumped straight into using the trendy Next.js framework. With the help of third-party APIs, I built a site for automatic image expansion. However, it hasn’t gained traction yet. Oddly enough, despite adding many backlinks, only the one from a site was picked up by Google Search Console.
----Main Point----
After reviewing my experience with these previous sites, I’ve realized that it’s not necessary to develop all the features before launching. Instead, it’s better to start with a landing page, focus on SEO, and then develop additional features once the site’s Google ranking improves. With my previous site (https://aiexpandimage.org), I finished the landing page in just a few hours, but spent a good week or two developing the features.
Currently, the average Google ranking is around 64, so it’ll take time to gradually add backlinks and promote the site.
I’ve wisened up now. For my new site (https://ai-hug.org), I’ve only created a landing page. I’m focusing on SEO first, and I’ll develop the core features and payment system once the traffic starts coming in.

8. Show HN: Gauss-Engine v1 – Text-to-Human Motion Without Mujoco: Author’s Latest Innovation
URL: Visit Now
Author: richa_flutr
Description: We’re excited to introduce Gauss-Engine, a groundbreaking AI-native physics engine that allows creators to generate lifelike human motion from text prompts—without the need for Mujoco. Imagine designing complex interactions like walking, jumping, or even acrobatics, all while maintaining real-world physics accuracy.
Gauss-Engine leverages advanced techniques like hierarchical motion representation to capture fine details and ensure precise control over movements. By progressively refining motion at multiple levels, we can achieve high fidelity without sacrificing flexibility. Additionally, we employ context-aware generation, where models condition on previous motion data to maintain consistency and stability in long, complex sequences. This ensures that the generated motions are fluid and realistic, even across extended interactions.
Our approach enables creators to define detailed, environment-aware movements using just text, offering unprecedented control and flexibility in motion design. As AI-native physics engines evolve, the future holds vast potential for more immersive experiences in gaming, VR, and robotics—driven by precise, real-time motion simulations.

9. Show HN: Forms with OpenPGP: Author’s Latest Innovation
URL: Visit Now
Author: palk
Description: I’m Pal, the creator of an open source form/survey platform. It’s written in Rust and Svelte and it’s all on GitHub: https://github.com/palform/palform.
My aim is to do something similar to how Proton encrypted emails: keep it simple and user-friendly, so that basically everyone can switch to it from Google/Typeform.
Of course, there’s some compromises. You can’t really do integrations, since the server doesn’t have the raw responses to send anywhere. But there’s still tons of use cases where Palform’s features suffice.
The encryption is powered by the amazing Sequoia PGP library and simply uses OpenPGP. I know it’s not a perfect protocol, but it’s been around for ages and audited several times. Users need to be able to trust Palform, and a DIY obscure cryptographic system would make that hard. Plus, this way you can import + export your keys and everything stays interoperable. It even has webhooks, so your servers can store PGP keys and you can decrypt the form responses yourself.

11. Show HN: A Wordle-Inspired Puzzle Game with Images: Author’s Latest Innovation
URL: Visit Now
Author: sakerbos
Description: Howdy HN folks!
I’ve been working on What The Pix Say (WTPS), a Wordle-inspired word puzzle game where you solve phrases by guessing the meaning of images.
Here’s how it works:
- Each phrase is represented by a set of images.
- You drag the images into place to form a phrase or sentence.
- The game accepts partial matches, so you don’t always need to be exact. For example, an image of a theater might represent “the,” or an image under a bridge could symbolize “under.”
I use AI to help generate the games and images (they can be quite hilarious at times).
Would love to get your feedback before I release this into the wild!
Cheers, Shaun
PS: If you’re curious about how I built it, I recorded the whole process here: https://www.youtube.com/watch?v=dnV0d-Nflqk&list=PLYM7y5xhAU….

12. Show HN: TranslateMyCall.com, an AI interpreter for phone calls: Author’s Latest Innovation
URL: Visit Now
Author: kolchinski
Description: Hi folks, Alex here with a launch I’m hoping for some feedback on!
I recently finished what started as a hackathon-style project with a friend, which has now become TranslateMyCall.com.
The problem we set out to solve is that there’s currently no way to interpret phone calls between languages without a human in the loop. Apps like Google Translate work well for in-person conversations, and Skype (surprising, right?) is the best I’ve found for VoIP interpreting. But for traditional phone calls, your only option is paying $1 to $4 per minute for a human interpreter through a service like LanguageLine. Even then, it can take 5-10 minutes to get connected, and interpreter availability/quality can vary.
We thought building an AI app to interpret phone calls between languages would be simple (famous last words…) but quickly learned why nobody else has done it. Building telephony integrations through Twilio was a huge pain, and phone audio is low-quality (8KHz/8-bit), making high-accuracy transcription difficult, especially for non-English languages.
In fact, transcription turned out to be the crux of this whole project. Translating transcribed text and synthesizing translated speech were easier, but balancing transcription quality with low latency became our #1 challenge. High transcription accuracy is possible if you’re willing to wait 10+ seconds with models like Google’s Chirp 2, but for real-time conversations, that’s not acceptable. Other models like Whisper and Deepgram are much faster, but often gave us unusably bad results for phone audio, especially in non-English languages.
After months of iteration, we’ve put together a system that glues together a number of AI models, both open-source and API-based, in ways that compensate for each others’ weaknesses while minimizing latency. (Sorry I can’t share more details yet — we’re keeping a few secrets while we try to commercialize this.)
The funny thing is, what we’ve built is probably going to be obsolete soon as foundation models get better and better. But for now, it seems that we’re the first working solution for this problem.
Now that we have a working product, we’ll be exploring B2B use cases for TranslateMyCall.com, but for now and into the foreseeable future, we’re releasing it as a free public alpha. To try it out, go to www.translatemycall.com, select your language and phone number (we support 40 languages and 36 country codes), and the other person’s language and phone number, and both of you will receive a phone call connecting you through an interpreted line.
Please let us know what you think, especially any suggestions for improvement! And if you know someone who might benefit from this, we’d appreciate it if you share it with them. You can reach me with any questions or feedback here or at [email protected].

22. Show HN: Visual DB – Web front end for your database: Author’s Latest Innovation
URL: Visit Now
Author: visualdb
Description: If you have a cloud-hosted database, read on: Visual DB was designed for you.
Visual DB is the fastest way to create data entry forms for your database: Starting with an Excel spreadsheet, you can import your data into the database and create a great-looking form in under 10 minutes. Watch this video: https://youtu.be/6rVD5rmrjN8
Visual DB is a comprehensive SaaS frontend for your database. In addition to data entry forms, Visual DB also has a spreadsheet-like interface for inserting and updating data in your database. You can also build interactive reports using Visual DB. Finally, although not intended as a replacement for your database’s admin tool, Visual DB can browse schema, create tables, set up relationships, and import and export data.
Visual DB began as a drag-and-drop form builder for databases. Forms created with Visual DB are practically indistinguishable from those hand-coded using React. You can add client-side validation, set available values (displayed in dropdowns), define default values, and even add logic to dynamically hide or disable fields—all without writing a single line of code! With Visual DB Forms, you’ll never have to write another CRUD app again.
If you have been using Excel to manage data and running into its limits because the volume of data has grown, Visual DB Sheets may be of interest to you. With its spreadsheet-like interface, Visual DB Sheets allows users to interact with data as they would in Excel, while securely storing that data in a robust relational database. Spreadsheet-database hybrids have been around for a while now, but we believe we have one of the best implementations, with features such as advanced grouping, support for foreign keys and lookup tables, query parameters, full-text as-you-type filtering, and so on.
The newest feature of Visual DB is interactive reporting. Traditional reporting tools offer limited interactivity. For example, while most reporting tools support time series charts, they do not allow users to zoom or pan along the time axis. In contrast, Visual DB supports this capability thanks to its innovative approach: it downloads the dataset to the client and processes and visualizes data directly in the browser. This allows it to handle user interactions without a server round trip. Visual DB has excellent support for query parameters, which allows you to bring only the subset of data that’s of interest (up to 100K rows), to the client.
Visual DB supports PostgreSQL (including Neon), MySQL, SQL Server and Oracle. Give it a whirl, and we look forward to getting your feedback: https://visualdb.com

24. Show HN: Balloonist – Balloon inspection drawings and extract features (QC Tool): Author’s Latest Innovation
URL: Visit Now
Author: SeaMetal
Description: In manufacturing, quality control teams will often need to ‘balloon’ or ‘bubble’ inspection drawings so that each feature on a part can be inspected. They then need to have these features and tolerances listed for first article inspection (FAI) reports and data collection.
This involves using specialized QC software, which is often expensive, or using a PDF editor, which is time consuming and repetitive.
Balloonist is an affordable alternative which helps streamline the process.
My hope is that balloonist might be beneficial for smaller machine shops and jobs shops that need an alternative to using a PDF editor, but my not have the budget for or the need a full fledged QC suite.
Feedback on the landing page and/or app is welcome and appreciated (you can get a free 7 day trial, no cc req’d, at https://app.balloonist.io)

26. Show HN: AI Election Predictor – Test Your Voting Demographic: Author’s Latest Innovation
URL: Visit Now
Author: jcpy
Description: I’ve built an MVP that uses AI to predict voting patterns based on demographic data. You can try it here without signup: https://tinyvotes.com/
What it does:
- Input parameters like age, gender, state, county, education, and income
- AI predicts and classifies voting choice for that demographic
- Global counter shows aggregated voting statistics
Tech stack:
- Frontend: Vite for fast development and optimized builds
- Backend: Firebase ecosystem
- Firestore for real-time database
- Cloud Functions for serverless logic
- Cloud Storage for parameter and prediction logging
- Firebase Hosting for deployment
- AI: Leveraging both Grok and Gemini for predicting and classification
Why I built this:
- Curious about the intersection of AI and political forecasting
- Wanted to create a tool that could potentially offer more granular insights than traditional polling
- As an immigrant, I’m fascinated by the diverse political landscape of the US - This project helps me (and potentially others) understand the complexity of American demographics and voting patterns
Some interesting findings so far:
- Not everyone in California votes for the Democrats, contrary to popular belief
- The combination of younger age, female gender, and lower income shows a higher probability of being undecided
- Most intriguingly, the AI sometimes predicts “undecided” as an outcome, despite not being explicitly prompted with this option. This showcases the LLM’s ability to capture nuanced political stances beyond simple binary choices.
I’m particularly interested in:
- How accurate do you think this kind of tool can be?
- What are the ethical implications of such predictions?
- How might this impact traditional polling methods?
All feedback welcome - on the concept, implementation, or potential use cases.

28. Show HN: GitOps Template for Kubernetes: Author’s Latest Innovation
URL: Visit Now
Author: pmig
Description: Hello HN, we’re Philip Louis from Glasskube (https://github.com/glasskube/glasskube). We are working on a package manager for Kubernetes to simplify the packaging of complex applications with multiple dependencies, ensuring they are installed and kept up-to-date across multiple Kubernetes clusters.
Nowadays, it is best practice to use Git as a revision control system for your Kubernetes configurations. Update automation workflows like Renovate or Dependabot can create pull requests for new versions of Docker images and Helm charts, but ensuring these new package versions work is still a manual task. By using the central (or a private) Glasskube repository (https://github.com/glasskube/packages) together with our Renovate integration (https://docs.renovatebot.com/modules/manager/glasskube/), you can ensure that new package versions will run through our Minikube-based CI workflows before they get published—similar to how the Homebrew core tap works. We’ve just introduced readiness checks for manifest-based deployments and utilize the flux-helm-controller to wait for a Helm release to succeed.
Dependencies are resolved by our package controller. These dependencies can either be cluster-scoped (installed in the recommended namespace, e.g., operators wird CRDs) or namespace-scoped components of a package (e.g., a database or Redis cache). In such cases, we will prefix resources with the dependent package name to ensure multiple packages can use the same dependencies without naming conflicts (we use Kustomize on a virtual filesystem for this).
Glasskube packages can currently be Helm charts (from an OCI or Helm repository) or manifests, which are mostly built using Kustomize’s overlay approach.
Since neither the overlay approach (using Kustomize) nor Helm’s limited templating functionality will help us and other Kubernetes users scale to more complex packages, we are considering creating a more programmatic approach to package creation, similar to Timoni. Currently, KCL is our frontrunner (https://github.com/glasskube/glasskube/discussions/1018), as it already integrates well with the Kubernetes ecosystem.
We would appreciate if you give our GitOps template a try. It also works work existing Kubernetes clusters if just want to use GitOps for some applications. Just make sure that the argocd and glasskube-system namespaces are not yet in use. See: https://github.com/glasskube/gitops-template/

33. Show HN: DBOS transact – Ultra-lightweight durable execution in Python: Author’s Latest Innovation
URL: Visit Now
Author: jedberg
Description: Hi HN - DBOS CEO here with the co-founders of DBOS, Peter (KraftyOne) and Qian (qianli_cs). The company started as a research project of Stanford and MIT, and Peter and Qian were advised by Mike Stonebreaker, the creator of Postgres, and Matei Zaharia, the creator of Spark. They believe so strongly in reliable, serverless compute that they started a company (with Mike) to bring it to the world!
Today we want to share our brand new Python library providing ultra-lightweight durable execution.
https://github.com/dbos-inc/dbos-transact-py
Durable execution means your program is resilient to any failure. If it is ever interrupted or crashes, all your workflows will automatically resume from the last completed step. If you want to see durable execution in action, check out this demo app:
https://demo-widget-store.cloud.dbos.dev/
Or if you’re like me and want to skip straight to the Python decorators in action, here’s the demo app’s backend – an online store with reliability and correctness in just 200 LOC:
https://github.com/dbos-inc/dbos-demo-apps/blob/main/python/…
Don’t want to keep reading and just try it out:
https://console.dbos.dev/launch
No matter how many times you try to crash it, it always resumes from exactly where it left off! And yes, that button really does crash the app.
Under the hood, this works by storing your program’s execution state (which workflows are currently executing and which steps they’ve completed) in a Postgres database. So all you need to use it is a Postgres database to connect to—there’s no need for a “workflow server.” This approach is also incredibly fast, for example 25x faster than AWS Step Functions.
Some more cool features include:
* Scheduled jobs—run your workflows exactly-once per time interval, no more need for cron.
* Exactly-once event processing—use workflows to process incoming events (for example, from a Kafka topic) exactly-once. No more need for complex code to avoid repeated processing
* Observability—all workflows automatically emit OpenTelemetry traces.
Docs: https://docs.dbos.dev/
Examples: https://docs.dbos.dev/examples
We also have a webinar on Thursday where we will walk through the new library, you can sign up here: https://www.dbos.dev/webcast/dbos-transact-python
We’d love to hear what you think! We’ll be in the comments for the rest of the day to answer any questions you may have.

Description: Hello HN,
I want to show off something I’ve been working on for over a year.
I created a browser extension that records your screen and then sends keyframes over to the GPT Vision API for annotation.
The use case for my software is creating interactive product demos.
Here is my app giving a demo of itself (a milestone I am extremely proud of!):
https://www.interactivedemo.ai/d/APRNDj9hoONXXDu
In the demo, you can see how I’m extracting key frames from the screen recording and sending them over to the LLM with various annotations. I use AWS Lambda with FFMpeg layers for that.
For the keyframes, I draw a red dot on the cursor using Python Imaging Library (PIL) and I also draw sequence and timestamp information under the frames. I have a prompt I’ve been tuning for a while and it’s not perfect but, it still saves a ton of time and has great results.
The system prompt is:
“Generate brief, action-oriented web interaction descriptions. Use varied verbs, focus on direct results, and leverage provided context. Pay close attention to both original and scaled coordinates.”
but the user prompt is my secret sauce ;-)
I am launching it on Product Hunt in a few days here:
https://www.producthunt.com/posts/interactivedemo-ai
I created InteractiveDemo.ai because I like how Screen Studio feels, but it is Desktop Mac only, and it doesn’t have interactive features. Also, I like the ability to create my own A.I. features on top of interactive demos and just the space in general because I’ve been developing and showing off software for 24 years. It’s a natural fit for me.
Check it out at https://www.InteractiveDemo.ai
I’d appreciate your support and am happy to answer any questions HN has.

36. Show HN: I built a Chrome extension to make interviews less daunting: Author’s Latest Innovation
URL: Visit Now
Author: ebloom19
Description: Hey HN community!
As a software engineer who took an unconventional path (bootcamp graduate in late 2021), I’ve spent the last 3 years in the 9-5 grind, constantly dreaming of building something meaningful. After watching my brother struggle with interview anxiety, I built Acedit: an AI interview coach.
What it does:
- Provides real-time, personalised prompts during online interviews
- Parses job listings for targeted practice questions and answers (from popular job listing websites LinkedIn, indeed, etc…)
- Offers mock interview simulations
Tech stack: NX Monorepo, Express, React, Playwright (e2e testing), Supabase (auth/DB)
What sets it apart:
- Chrome extension format (less intrusive than a PWA)
- Ability to seamlessly parse info from the users active tab (allowing for quick and easy extraction of listing information)
- Free tier with unlimited live interviews (uses gpt-4o mini)
Biggest challenges:
- Balancing helpfulness with ethical use (it’s a coach, not a cheat sheet)
- Optimising AI response time for real-time use
- Building accurate “Question Detection” using NLP
I’d love your feedback on:
- Ethical considerations - how to ensure proper use?
- Performance optimisation ideas
- Potential expansions (e.g., LinkedIn lead generation, more in-depth practice modes)
Thanks HN! Excited to hear your thoughts and answer any questions.

Author: cylo
Description: I’ve always been fascinated by the history of how open source projects evolve but reading through commit histories takes a lot of effort to get context. So I had the idea to create the Git Pulse service as my nights-and-weekends project.
I’m using open source LLMs to summarize commits across several popular open source projects and providing them here in one central location. I think there’s a lot of value for both developers and non-developers to better understand what’s going on in these projects on a daily basis.
So far I’m covering FreeBSD, OpenBSD, Illumos, OpenSSH, PostgreSQL, SQLite, and Linux. I’m still working through the historical backlog of Linux and will look into adding more projects going forward.
I’d love your feedback for making it better.

39. Show HN: My attempt at injecting creativity into a stale genre [video]: Author’s Latest Innovation
URL: Visit Now
Author: ambyra
Description: I got the idea for this watching a lot of Chernobyl Family. Typing “soviet control room” into google gives a lot of cool pictures, usually with a giant depiction of the core in the center of the room.
The Soviets had to smuggle in Intel and IBM tech during the cold war, so no one had access to good computers, except at work. I imagined a bored engineer at Chernobyl Nuclear power plant with the most powerful computer in Russia behind him, SKALA. He modifies the computer control program so it is more fun to play. He sets off larger and larger chain reactions while still keeping the reactor sub-critical, until one day, meltdown. Years later, he sneaks back into the rubble, steals the control code and publishes it as an internationally popular video game, called Reaktor.

41. Show HN: I made a native HTML5 animated banner generator: Author’s Latest Innovation
URL: Visit Now
Author: ress
Description: I want to share the tool I have been working on for almost a year. It takes a multi-frame Figma design and converts it to native HTML5.
Then applies a preset animation to elements based on their type. The result is an animated HTML5 banner ad from a static Figma design, with each frame appearing in sequence and delivering the marketing message.
For example:
- Frame 1: Name the problem
- Frame 2: Show your product
- Frame 3: CTA or disclaimer
You can process many sizes at once, such as 300x600 with 2 frames + 728x90 with 4 frames + 1080x1080 with only one frame. So all creatives are animated in a second.
Building this tool with ad creative automation in mind, as my entire background revolves around display ads. I also tried to make it developer friendly. It generates tiny human readable HTML+CSS code.
I think this would be helpful for brands and marketing teams and want to get as much feedback as possible.
Thanks for your time and support. Alex

42. Show HN: YourNextStore – an open-source Shopify with Stripe as the back end: Author’s Latest Innovation
URL: Visit Now
Author: zaiste
Description: We’re building Your Next Store, a modern, ultra-fast, open-source commerce in Next.js with Stripe as the backend - no DB required.
Selling online is often more complex than it needs to be. Setting up a storefront with great performance can feel daunting and time-consuming. There are many plugins, libraries, etc - the choice can be overwhelming.
Plus, in e-commerce, the backend and frontend are often written in different languages (e.g., PHP, Python, or Ruby for the backend). This increases the complexity and makes code management more challenging, especially for teams.
After working in e-commerce for several years, Michał and I set out to build the fastest and most compelling storefront for small to medium-sized merchants. Fast e-commerce sites are crucial because slow pages hurt sales [1]. Unfortunately, performance issues are still very common. The beauty of Your Next Store is its simplicity. No additional tools and no databases - just Next.js and Stripe.
On the technical side, we use App Router, React Server Component, Partial Pre-Rendering, Optimistic Updates, and Streaming with Suspense to make the store faster and leaner so it feels almost like a static website.
In summary:
Modern & Popular Stack: Built with Next.js, React.js, and TypeScript, making development faster and hiring easier compared to platforms that use less common frameworks like Shopify’s Liquid.
No Database Needed: Stripe handles the backend, reducing the need for complex infrastructure and simplifying the setup process.
Open Source: Free and open (AGPL), with the option for a commercial license if needed.
This is just the beginning. We want to make YNS even better and easier to use and eventually provide a good, open-source alternative to Shopify.
Check our code at https://github.com/yournextstore/yournextstore

43. Show HN: RAG Large Data Pipeline with 1000 Models: Author’s Latest Innovation
URL: Visit Now
Author: zh2408
Description: Hi, I’m a PhD in data + LLMs. I’m building an LLM chatbot for dbt.
The challenge isn’t LLMs but dbt pipelines, which are too large (e.g., >1K models) to fit in the context window.
Traditional vector RAG only works well for texts but poorly for SQLs.
To solve this, we built a novel RAG using lineage.
I tested it on dbt projects with 1000+ models, and it works very well.
Some cool use cases the such chatbot does well:
- Models discovery (I have a high-level question, which tables to use?)
- Safe model edits (I want to edit the models, what downstream models are affected?)
- Model debugging (This column looks wrong, how is it computed upstream?)
- New pipelines prototyping (I want to add a new metric, how are similar metrics computed?)
- Natural language querying (I want to understand customer better, recommend some queries)
- Pipelines optimizations (This model is slow, any inefficiency in the pipeline?)
- etc.
Live demo on RAG for the Shopify dbt project (built by Fivetran): https://cocoon-data-transformation.github.io/page/pipeline
Enter your question, and it will generate a response live (refresh the page for the latest messages).
Video Demo: https://www.youtube.com/watch?v=kv5mwTkpfY0
Notebook to RAG your dbt: https://colab.research.google.com/github/Cocoon-Data-Transfo…
You’ll need to provide LLM APIs (Claude 3.5 strongly recommended) and a dbt project (just need target/manifest.json).
The project is open-sourced: https://github.com/Cocoon-Data-Transformation/cocoon

Author: psycookie
Description: Hey HN!
When implementing an AI-powered feature for a project, we—and many people we’ve talked to—often reach a point where we have to choose an AI model but aren’t sure which one best fits our constraints or where to even start.
Unfortunately, the advice to “just use chatgpt” is not always a good one. What if I want an open-source model? What languages does it support? What about context window size or the number of parameters? There are thousands of AI models already out there and many of them are perfect for certain problems.
That’s why we’ve carved out this part of our product as a free tool (some features require sign-up) to help navigate AI models (NLP models for now). Hopefully, it will be helpful resource for the community.

52. Show HN: Free Basketball Practice Plan Creator for Youth Coaches: Author’s Latest Innovation
URL: Visit Now
Author: jordanmorgan10
Description: Hey hey HN,
TL;DR: I built a free tool for youth basketball coaches to easily create customized practice plans. One pain point I see in grassroots basketball is that youth coaches need help with practice plans. It could be for a variety of reasons — they are new to the game, volunteering their time, just need ideas, etc.
So this tool I made has you to select your team’s age, skill level, and focus areas (like ball handling, shooting, or defense, press breaks, etc), and then it customizes a complete practice plan. Each plan creates a unique link, so you can share it with anyone (your team, parents, other coaches, etc).
I also have a video demonstration embedded in this blog post: https://www.elitehoopsapp.com/Free-Youth-Basketball-Practice…
I’d love any and all feedback on how this could be more useful, and feel free to try it out! This is my first web project (iOS developer) so I’m especially eager for any thoughts on that front.

Author: timkonie
Description: Hey HN!
I kept seeing those awesome animated screen recordings on X and wanted to make videos like that too. I couldn’t find any good screen recorders with automatic effects for Windows, so I decided to build my own!
It currently
- makes the cursor smooth
- follows the cursor
- zooms in on clicks
- records & animates webcam
- and a bunch of other stuff that’s available in the editor (change background, generate subtitles, speed up video segments…)
It’s a paid app but there’s a free trial if you want to play around with it - I’d love to hear what you think!
PS: I’m aware of the warning when downloading / installing the app. It’s because I can currently only sign the installer with an IV code signing cert. Unfortunately there isn’t much I can do at the moment - apparently code signing is hard and quite gatekeep-ey.

URL: Visit Now
Author: domysee
Description: I developed a small tool to find RSS feeds for websites. You can try it out here: https://lighthouseapp.io/tools/feed-finder
In >90% of cases the standard way of checking meta tags is enough to find the feeds. But my goal for this tool is that it finds feeds regardless if they’re linked somewhere or not. That if this feed finder doesn’t find a feed, no feed exists.
It’s a big goal and admittedly not there yet, but it does a few things that are a step in that direction.
* Checks meta tags of parent pages (sometimes the article itself doesn’t have the meta tag, but the main blog page does)
* Checks common suffixes like /rss, /index.xml and many others (sometimes the feed exists but isn’t linked)
* Checks the sitemap
* Checks all links on the page
* Checks 3rd party feeds (OpenRSS for now, when I find more such repositories I’ll add them too)
There are a couple of additional ideas I have, like checking search engines and crawling the entire domain (highly inefficient, but possible).
Would love if you could try it, and even more if you post sites where it doesn’t work.

Author: NabilChiheb
Description: So I’ve been doing the whole self-publishing thing on KDP for a while now, .
But recently, I ended up building a tool, and the idea came from the most unexpected places—my 5-year-old .
My kid is constantly coming up with these wild, creative stories, and my wife suggested I turn them into books. Seemed like a great idea…
until I realized how hard (and expensive) it is to get good illustrations done—especially when you’re self-publishing on a budget.
That’s when I had this lightbulb moment:
Why not build a tool that can generate illustrations for me?
That’s how StoryArtAI was born. It’s a tool that takes your story or prompts and generates consistent character illustrations throughout the book—no illustrator fees, just some AI magic.
You get different styles to choose from—like watercolor, line art, or even collage, so no matter what vibe you’re going for, we’ve got you covered.
And here’s the best part: It’s free to try! You get 20 free generations upfront, so you can test it out without paying a dime. Whether you’re new to this or just want to check it out, it’s a great way to get started.
If this sounds like something you’d want to try, check out StoryArtAI.com.

URL: Visit Now
Author: leetpro
Description: Hey HN — we’re University of Waterloo grads, and we’re building LeetPro (https://tryleetpro.com). LeetPro is Leetcode but for soft skill-based questions and cases. In other words a platform designed to help you nail behavioral, product, and case-based interviews just like Leetcode does for technical interviews. We’re combining AI-driven mock interviews with community-driven content to create a comprehensive preparation tool for systems design, product, and business interviews. We came up with this idea just last week, and we’ve already launched an MVP that’s worth checking out if you’re interested https://tryleetpro.com
Why you ask? (Eric) As I started pivoting from software engineering to product management, I noticed a HUGE difference in the structure between preparing for technical roles versus product management, business, and finance roles. Leetcode made technical prep straightforward, but there’s no equivalent for the soft-skill-heavy interviews in the finance, business analyst, and product management spaces. That’s where we’re hoping LeetPro comes in. In the future, we’re hoping to build LeetPro into a product that allows users to browse a wide range of community and internally sourced interview questions, cases, and prompts. From there, you can conduct a mock interview with a realistic AI interviewer that mimics the experience of a real interview. Afterward, you receive a detailed score and breakdown of your performance, along with precise feedback on how to improve. We’re also planning future iterations that will analyze non-verbal cues like confidence, personality, and body language.
If you’ve ever struggled with preparing for a behavioral or case-based interview or know someone who is, we’d love for you to give LeetPro a try. We only built this in the last 48 hours and we’re hoping to just understand whether this is a product that people are interested in! We’re eager to hear your feedback and answer any questions in the comments!

68. Show HN: Lucidcode- A Copilot to Understand Codebases: Author’s Latest Innovation
URL: Visit Now
Author: pushpankar
Description: Hello HN, I am building a devtool to understand existing codebases. The idea originates from my time at big tech as well as various attempts to get involved in open source projects.
When I was in college I wanted to improve my coding skills by contributing to opensource projects. I would pickup a bug or feature request but I always found myself stuck at the very first step. I did not understood where and how to begin contributing. I once submitted a patch in firefox which was labeled “Good first issue” but that was still very handheld. The assigner told me exactly which files I need to update and what changes are needed. It took me a week to push the patch. But I didn’t feel good about it because the guy could have done the same task himself in 10 minutes and he had to spend significantly more time telling me to what to do. Then for years, I made very few contributions and that too where I knew how the project is organized by working on it as part of my day job.
I found similar issue while working at Amazon. Very often you need to work on projects handled by other teams or code which are not being maintained. And the problem boils down to where do I even begin. Which components are responsible for what. Once you understand that, it is significantly easier to figure out what needs to be done. Plus many big tech companies follow something called bus factor. The logic goes like like this: if one of the team mate is hit by a bus the development of the project should not stall. So you need to abandon project which you just understood well. So you often end working on new codebase all the time.
Lucid code is my attempt to solve this problem. It helps you quickly figure out which parts of code are responsible for what. To test the utility of my tool, I decided to contribute to an opensource project which I was not familiar with and see how long that takes. I choose manim to do so. I was able to get a high level overview of the codebase in couple of hours. And I was able to create a custom animation in another hour or so. Biggest help I found was that at no point I was completely lost.
As of now, the tool is not so good that helping you bug fixes as a lot of bugs are situational error(xyz happens when the value of abc is 123 etc). These are more suited to setting up the environment, firing up the debugger and reproducing the bug. But I have plans to extend tool to help in this kind of situation as well.
I would love to get your feedback and suggestions. You can try the tool for free without the need of a signup. Please try it and let me know here or at [email protected].
Thank you, Pushpankar
