Author: rahimnathwani
Description: I was using Hamel Husein’s ‘Claude Save’ Chrome extension, but it no longer works because it seems chats are no longer stored in LocalStorage.
If you have ever tried printing (or saving as PDF) a Claude conversation, you’ll know that you only get what’s currently on the screen.
So I made this, which downloads the conversation as an HTML file which easily be opened, viewed and printed.
I just submitted it to the Chrome Web Store, so it’s not available there yet.
Installation instructions are in the README.

4. Show HN: Turn Any Image into an AI-Powered Conversation
Author: rriley
Description: I have been working on this Chrome browser extension called roleplayr.ai. It lets you have a conversation with any image you encounter online. Simply click on an image, start a conversation, and let AI bring it to life with unique responses based on its context.
I love the idea of turning visuals into interactive experiences. Imagine chatting with the Mona Lisa about Renaissance fashion or asking a historical figure about their life. Memes become punchlines waiting to happen. Roleplayr.ai turns visuals into engaging, AI-driven dialogues.
I believe this is a new way to explore the web. I hope you’ll check it out and let me know what you think.

12. Show HN: I Built a Rock, Paper, Scissors roguelike in React
Author: xtremerps
Description: Hey HN! What started off as a meme has turned into a passion project and I’m pretty excited about it. As the title suggests, I made a Rock, Paper, Scissors game in React. The twist is the perk shop that you can power yourself up upon wins.
I have a Node web socket backend because it started off as just a PvP experience, but I wanted people to be able to play a solo mode. That’s where the Roguelike comes in. I still have plenty of features to go! But for now, it’s an endless Roguelike where after each round, you get to upgrade a shop perk to make your character stronger.
I’d love to get some feedback! Feel free to try it out and ask any questions! No login or account needed.

14. Show HN: Wordy – Learn English Vocabulary from Movies and TV Shows
URL: https://apps.apple.com/us/app/master-english-wordy/id6670703228
Author: sandorb
Description: Hey HN,
I built Wordy, an app for learning English vocabulary directly from movies and TV shows. As an English learner myself, I wanted an immersive way to pick up vocabulary, so I created this tool to make it easier and more effective.
Key Features:
- Extensive Vocabulary Database: Access vocabulary from 500,000 movies and series, categorized by proficiency levels (A1-C2).
- Real-Time Subtitle Sync: Wordy “listens” to where you are in the film and syncs with English subtitles, so you can learn as you go without pausing.
- Instant Definitions and Translations: Tap any word for a contextual definition or translation, which helps with understanding slang and nuanced expressions.
- Flashcard Generation: Words are saved into flashcards, organized for spaced repetition, so you can review and reinforce new vocabulary easily.
Would love to hear your thoughts or ideas for improvement!
Cheers, Sandor

15. Show HN: I made an interactive sentiment model comparison site
URL: https://addmaple.com/sentiment
Author: hitradostava
Description: Hey HN, I needed to assess the state of sentiment models and couldn’t find a good way to compare them. I built this interactive site that lets you compare 12 models side by side, from Python libraries like NLTK Vader, to top performing models on HuggingFace, to commercial sentiment APIs and GPT4o.
This is a research project, there is no paywall - you can enter your own text (1) and get the results back immediately. The results are fascinating and we made it easy to explore not just the leaderboard, but where models get it wrong.
For example, most models (including AWS Comprehend) can’t get this positive sentiment:
“Food doesn’t get better than this. I was sad when I finished, actually sad. To die for.” (2)
And yes, GPT4o is currently the best performing. It’s crazy how many laboriously researched models are superseded by general purpose foundation models.
Let me know what you think?

I built lazel because i wanted to get more organized, but was too lazy to do it myself. The extension is still under verification and not yet published, but i figured that it might be better to share as its fairly easy to set up locally and modify it to fit your needs.
Right now it only supports Goggle Tasks and Google Calender, but the idea is to integrate more services.

17. Show HN: Termfu – A terminal debugger with custom layouts
URL: https://github.com/jvalcher/termfu
Author: metadigm
Description: Hi HN,
First “Show HN” post!
Termfu is a fast, multi-language TUI debugger that allows you to create and switch between custom layouts.
I couldn’t find a terminal debugger that fulfilled my particular needs and desires, so I create one that does for the most part. On the UI spectrum, it’s somewhere between GDB’s TUI and Vimspector. It currently supports GDB and PDB. It uses customizable, single-key bindings, which can be documented on screen via their (t)itles. All window data is scrollable. I decided to have some fun with the layout creation process, which uses “key-binding ASCII art” to set the header command title order as well as the window positions and size ratios. For example, a configuration for a single layout would look something like this:
It’s still pretty rough around the edges, but it has become a valuable tool for me, so I thought I’d go ahead and post it here. Please note that I am far from a C expert. Somewhere along the line, I got it in my head that a C project is a rite of passage, so here we are. If I hadn’t had Gookin’s Ncurses guide to get me started, I might already be dead. That being said, feedback is very much appreciated.>h abc dEfghi

22. Show HN: What Could It Cost?
URL: https://whatcoulditcost.amandhoot.com
Author: deltaknight
Description: What Could It Cost? challenges you to see if you really know how much you’re spending on your groceries.
It’s a simply daily-puzzle-style game that gives you 5 products from trolley.co.uk’s Grocery Price Index, and asks you to guess how much they cost. The closer you are to the actual price, the more points you get. The price is averaged across a number of UK supermarkets, with the prices from October 2024. So if you normally buy something for £1.99, it might show as an unexpected £1.87 as it’s averaged with another cheaper supermarket.
I often find myself not really noticing how much I spend on my individual items when shopping (I must be far too middle class), so thought I’d test out my knowledge, in a similar sort of way to the Name Your Price gameshow.
The site is open-source, you can find the GitHub link on the homepage. I made this so that I could learn more about Elixir & Phoenix LiveView, so the code is by no means clean at all :). I hope to clean it up as I learn more about Elixir.

23. Show HN: Saphira – Understand Standards and Deliver Compliant Hardware
Author: akshayc
Description: Hey HN! We’re Oscar and Akshay from Saphira (https://saphira.ai). We collaborate with robotics and aerospace companies to certify their products, which requires us to be deeply familiar with relevant standards and frameworks to produce requirements and test lists. To automate our work, we built an AI agent that we’re making publicly available that specifically searches for appropriately structured technical details in these large, hierarchical documents. Here’s a demo: https://youtu.be/XJlthEtetb8.
If you’ve ever had the fortune of digging through ISO or UL standards or OSHA/FAA CFRs to build a safety case while preparing for certification of a hardware product, you know that it can quickly become a hot mess of references to dozens of sub-frameworks. That’s what we encountered and have tried to fix.
We’ve learned by writing safety cases and building compliance plans that this agent must be able to do things like identifying exactly the right section of a standard that applies to a particular topic of consideration, such as the insulation width for a particular wire in a robot to prevent heat and current transfer in order to produce touch safety, which is actually directly stated in the appropriate substandard section!
When identifying these sorts of sections, we must then be able to reference a knowledge graph derived from the standard to identify which substandards to traverse to, and critique identified sections to state whether they actually contain technical details, or just definitions or further references.
You can log into Saphira at the provided link, specify details about your project to allow us to associate relevant standards with your project, then start issuing these sorts of queries for free! You can even upload arbitrary documents to our Context Store to try this out on specific complex documents you wish to traverse!
We’re actively improving all of this, so please share any feedback!

24. Show HN: Autotab Instruct – Claude Computer Use with Guardrails for Reliability
URL: #
Author: jonasnelle
Description: Hi HN,
We’ve built a desktop app to create highly reliable AI agents that use a computer with mouse and keyboard.
Until last week, we had tried many different approaches to open-ended agentic features but none of them had met our reliability bar.
With Anthropic’s Computer Use this finally changed, and we just shipped a feature we’re calling Instruct. Instruct allows users to create agentic blocks as part of a larger Autotab skill that provides the structured logical flow to keep the automation on track.
If you haven’t had a chance to try Computer Use yet, it is an impressive leap from the last generation of vision models (e.g. gpt4o struggles with relative positions, let alone coordinates). At the same time, it is still not good enough to be given a prompt and let loose.
One of the big surprises to us early on was just how much intent specification is required for most real world workflows to run reliably. What looks at first like a simple form filling task usually turns out to have dozens of edge cases and super specific, hidden rules. Even human employees need to be shown how to perform these tasks, and then refined with question-asking + feedback over time.
We wanted to build a tool for specifying intent, and iterating with the model to make it reliable enough for real work.
- Automations run on top of an action scaffold, which works kind of like a very fuzzy programming language with strict types. This gives the model a high level plan that guides execution, and makes it easy to break out discrete steps to get the reliability you need. (Interestingly, this has also proven useful not just for the agent, but also for the human trying to create, verify and edit the automation.)
- When the model is unsure it asks for clarification. For example, if you are in editing mode and the model thinks that an element looks meaningfully different than before, it will ask you to verify that it is the same element.
- The agent has access to a memory system that lets it recall information from past runs as well as instructions and feedback from the user.
Here’s a short video of Autotab Instruct in action: https://www.loom.com/share/ccf4e9d8c798450da3324a6cff024971?…. There are a few more demos at https://twitter.com/autotabai/status/1852393973165199425 a75f06f82cab521bc78672ed35d85e8a.

URL: https://massapply.io
Author: kylem866
Description: Finding a new SWE job sucks. I know from going through several grueling job hunts myself how exhausting it can be—especially if you’re juggling a day job or coursework.
One of the biggest pains in the process is having to send out endless applications. In 2024 many candidates have to submit hundreds of applications in order to land a role. Filling out applications is a time-consuming chore that could be better spent on interview prep, networking, or watching paint dry.
I created MassApply to relieve SWEs of this tedious duty. MassApply handles the bulk of applications for job-seekers. Candidates fill out a form with their preferences (title, location, minimum TC, etc.), and we submit applications on their behalf.
We’re offering a free beta of 40 applications to select users. Sign up on our website if you’re interested!

29. Show HN: Exploring Russian Election Interference with Graphiti
URL: https://blog.getzep.com/russian-influence-operations-graph/
Author: roseway4
Description: Hi HN, we’re Jack and Daniel from Zep. We’ve built a visual exploration tool and AI assistant for analyzing Russian election interference in the run-up to next week’s US elections.
The Explorer uses Graphiti, Zep’s open-source temporal Knowledge Graph library. Graphiti autonomously creates dynamic, temporally-aware knowledge graphs representing complex, evolving relationships between entities.
To offer users a detailed view of Russian state operations and related topics, we populated the graph with over 50+ sources. These include US DOJ indictments, research by US and foreign governments, research by non-governmental organizations, and media articles.
Using the graph, you can explore which US organizations and individuals are implicated in these efforts and learn how private entities (such as OpenAI, Meta, and others) have responded.
Two operations stand out in this dataset: Doppelganger and Tenet Media.
- Doppelganger: A campaign that used AI-generated content and fake accounts to spread anti-Ukraine propaganda and influence Western public opinion.
- Tenet Media: a media company secretly funded by RT (Russian state television), paid popular American influencers to create pro-Russian content across social media platforms.
The Doppelganger operation’s multinational scope required us to draw from both US and European sources to capture its full impact. For Tenet Media, we used diverse sources, ranging from federal government reports to Variety magazine’s industry coverage, to detail the company’s collapse and its broader implications for the media landscape.
To build the app quickly, we used FastHTML and LangGraph, a fun combination. The linked article explains how we built the Explorer and some of the challenges we faced, particularly around ingesting data.
Explorer: https://russia-elections24.getzep.com/
How we built it: https://blog.getzep.com/russian-influence-operations-graph/#…
We’ve spent hours delving into the data. We hope you find it as fascinating as we did.

URL: https://hackernewsexplorer.com/
Author: mahin
Description: The HN frontpage can feature stories that aren’t that relevant to me, and some good ones don’t get enough traction on the new submissions page. So I thought of building something that personalizes the stories you see.
This is done by getting the 500 newest and top stories and comparing them against your likes, building your own personalized homepage.
Also, when I find something I like, I usually want to explore similar stuff. So I created embeddings for 500k historical stories (all above 20 points) and added a ‘similar’ button that shows you the closest stories.
I thought of making this a web app, but I wanted something that integrated as seamlessly as possible with HN, so I decided on a browser extension.
I would love your feedback!

31. Show HN: Ratarmount 1.0.0 – Rapid access to large archives via a FUSE filesystem
URL: https://github.com/mxmlnkn/ratarmount
Author: mxmlnkn
Description: Hi HN,
Since my first posted introduction of ratarmount [0], 2 years have gone by and many features have been added.
To summarize, ratarmount enables working with archived contents exposed as a filesystem without the data having to be extracted to disk:
pip install ratarmount
ratarmount archive.tar mounted
ls -la mounted
Personally, I am using it view to packed folders with many small files that do not change anymore. I pack these folders because else copying to other hard drives takes much longer. I’m also using it when I want to avoid the command line. I have added ratarmount as a Caja user script for mounting via right-click. This way, I can mount an archive and then copy the contents to another drive to effectively do the extraction and copying in one step. Initially, I have also used it to train on the ImageNet TAR archive directly.
I probably should have released a 1.0.0 some years ago because I have kept the command line interface and even the index file format compatible as best as possible between the several 0.x versions already.
Some larger future features on my wishlist are:
- A new indexed_lz4 backend. This should be doable inside my indexed_bzip2 [1] / rapidgzip [2] backend library.
- A custom ZIP and SquashFS reader accelerated by rapidgzip and indexed_bzip2 to enable faster seeking inside large files inside those archives.
- I am eagerly awaiting the Linux Kernel FUSE BPF support [3], which might enable some further latency reductions for use cases with very small files / very small reads, at least in the case of working with uncompressed archives. I have done comparisons for such archives (100k images a 100 KiB) and noticed that direct access via the Python library ratarmountcore was roughly two times faster than access via ratarmount and FUSE. Maybe I’ll even find the time to play around with the existing unmerged FUSE BPF patch set.

35. Show HN: TotalPause – an app to suggest breaks and promote mindfulness
URL: https://tailloop.com/total-pause/
Author: damnever
Description: Hello, I created this macOS app because I often spend long hours at my computer without taking breaks. Although I’ve tried many similar apps, few really meet my needs. For instance, Pomodoro timers feel draining and don’t suit my work environment. Other apps often trigger breaks at inconvenient times, becoming more annoying.
I decided to develop my own app to try to address my own issues. My day job is as a backend engineer, primarily working with distributed systems and DevOps. I have knowledge of web development but had never developed a desktop app before. I started learning and building TotalPause in my free time last year. There is also a blog post[1] about why and how I built it.
The goal with TotalPause is to make it as unobtrusive as possible, requiring minimal interaction, making it appear less frequently as work habits improve, and avoiding the drawbacks of full-screen break reminders through technical implementations like auto-focus mode (automatically detecting applications, meetings, and games), activity analysis, and maybe other advanced features.
Hope to see if it works for others with similar needs. Thanks.

38. Show HN: Zidezi.app – A Wordle-Like app for language learning
URL: https://zidezi.app/
Author: bluemooner
Description: Hi HN! I built this app to help me stay consistent with learning a new language. It’s like “Wordle” but for language learning, with daily articles adapted to the user’s level. The app uses ChatGPT to generate fresh articles daily, and users can click on any unfamiliar word for an instant explanation. My goal was to keep it smooth and minimal — no clutter, just learning by discovery.
Each language has a distinct article, adapted to three levels: beginner, intermediate, and advanced. So all levels get the same topic, but the vocabulary and the grammar scale to match. I started with intermediate Spanish but moved to advanced over a few weeks as I progressed.
I’m thinking of adding features like an audio mode, more detailed grammar explanations (like verb conjugations and noun declensions), and spaced repetition to reinforce vocabulary you click on. The long term plan is to introduce ways to practice not only reading, but also listening and speaking. As it stands, you need a basic understanding of the language to use the app, so definitely not something for complete beginners. I’d love to hear any feedback or ideas!

42. Show HN: Serverless Apps on Cloudflare – A book on the Cloudflare dev platform
URL: https://pragprog.com/titles/apapps/serverless-apps-on-cloudflare/
Author: ashleypeacock
Description: Hello HN!
I am Ashley, author of the book Serverless Apps on Cloudflare, and I’m excited to share it with you and hopefully spread the awareness of the powerful and developer-focussed platform that Cloudflare has built, that I believe is currently flying under the radar!
For years, I’ve been building applications on Cloudflare - from websites, to APIs, to Discord bots and everything in-between. The platform has grown hugely in the past few years, to the point it has all the essential building blocks for modern applications. It’s also built with engineers in mind, the developer experience (imo) is second to none. AWS is powerful, vast and very widely used, but I don’t think anyone would shout about its developer experience in most cases.
Some of the features of the platform are incredibly unique and powerful. With a distributed architecture of many different services, you have to deal with services being down, or the network being down - with Bindings, you get a zero-cost abstraction to make inter-service calls between your different services (called Workers in Cloudflare) and they are automatically injected for you at runtime - no secrets, no credentials, no configuration - it just works. The same goes for databases, caches, queues and all the other supporting services you need - they all use bindings.
Everything runs seamlessly locally too, including databases, caches and everything else. No setup required, again, it just works and massively increases productivity and enjoyment when building applications. You don’t need to worry about failover or redundancy, your application and resources are deployed and available globally, thanks to the edge network Cloudflare runs.
The pricing is great too, you only pay for what you use. For example, the CPU time you use in a Worker, you don’t pay while your code waits on I/O (e.g. an API call), and there’s zero egress fees.
Lastly, they have a very unique concept called Durable Objects. You can think of these like mini single-threaded servers, that act as a way to coordinate multiple clients or a single entity. You write them the same way you’d write a class in your code, and Cloudflare takes care of persisting those objects and hydrating them with state - as they come with built-in state too (key-value or SQLite). They also have native WebSocket support, allowing you to add WebSockets to your application in literally a few lines of code - they are super cool.
That’s just a flavour of some of the cool offerings of the platform - if you want to learn more, it’s available in eBook format via The Pragmatic Programmers (https://pragprog.com/titles/apapps/serverless-apps-on-cloudf…), as well as available to preorder in physical format via Amazon (https://www.amazon.com/dp/B0DFNTSMHP?maas=maas_adg_968101BB2…). It’s content complete, and the beta tag will be removed in November.

44. Show HN: Block Sort, a mobile/PWA puzzle game without ads
URL: https://matthijsgroen.github.io/block-sort/
Author: thaisi
Description: I like small puzzle games to play on my mobile, (because you can put them away easily as well). But I got really annoyed that a lot of them force feed you advertisements.
To counter this I made my own puzzle game, as a progressive web app. This means you can install it on your mobile or desktop as an application, and play offline.
After the game is offline ready, no requests should be outgoing except checking for updates of the game. So there is no tracking/reporting going on. This also means I rely on old fashion email to get feedback!
The game is build in React + Typescript + Vite, and is open-source at: https://github.com/matthijsgroen/block-sort
Challenges:
- I wanted to make the game using open web standards such as HTML + CSS. The game actually features one image, the rest is done in pure CSS (the cubes, buffers and placement stacks);
- All animation is done through CSS animations;
- All levels are randomly generated, and then proven playable by a solver before a player gets the level on screen. To remove loading times for the high difficulty levels, a process was made to generate these levels offline, and the game only contains the random seeds to reproduce them (and then they are still solved by the game first before offering)
- The entire game is statically hosted, so there is no backend involved. This proved challenging for data transfer capabilities. The game now generates a QR Code image containing all encrypted/compressed game data, that can be loaded into another instance of the game.

55. Show HN: Makr.io – 15 Open-Source Utility Apps Built with AI in 30 Days
URL: https://github.com/renedeanda/makr.io
Author: iowadev
Description: Hi HN,
I recently completed Makr.io – 15 simple web apps, all open source on GitHub, created in just 30 days using Next.js, Vercel for hosting, and plenty of help from Claude and ChatGPT. Each app took me around 2-3 hours to build, with more time spent brainstorming ideas and framing problem statements.
Here’s my approach: I’d start with an idea and problem statement, then ask Claude for a detailed Python script to set up the project. Using the generated code as a foundation, I focused on refining essentials like mobile optimization and core functionality. This project was mostly built during early mornings and late nights as a personal challenge.
Here’s a sample of the apps:
SVG to PNG – Convert SVG files to PNG Email Preview – Preview HTML emails RSS Feed Reader – Read top RSS feeds DMARC Checker – Check DMARC records Event Countdown - Create countdowns for special days Email header analyzer HN client with dynamic sitemap
You can find the full collection on GitHub all open sourced.

57. Show HN: AutoSEO – Generate SEO-optimized blog posts to get more organic traffic
URL: https://autoseo.app
Author: striat
Description: Hey!
I built AutoSEO for myself since I needed a solution for my lack of SEO. As a very much non-writer, I have tried to generate something like this from the browser using Claude or in VS Code using Copilot. But neither work for the scale vs. time input I’m looking for.
There is something to be said for polluting the web with more AI generated listicles and posts. If I had built this 2 years ago I may have agreed with some ethical concerns, but I think Google search is far past the point where I would be concerned these days.

61. Show HN: Strava for Musicians
URL: https://www.musolink.com/
Author: mattfrasernz
Description: I have been working on a new app to help musicians get motivated to practice. Think Strava, but for musicians.
The challenge with music practice is that it’s invisible. It’s incredibly easy to skip a day because ‘nobody will know’. I have seen countless talented musicians stop enjoying their instrument and ultimately stop playing entirely due to this phenomenon.
MusoLink solves the problem by making your practice visible and social.
In my day job, I manage software engineering teams, and in my spare time I run Australia’s top pipe band. After using Strava to help get ready for a marathon, I realised something similar would be incredibly useful for the band. I couldn’t find anything so I started coding each night in front of the TV once the kids are in bed. This is the result!
I have had around 20-30 musicians each day helping me test and give feedback, but I’m ready to open it up to the world now! Already, a school has used it to prepare for a World Championship - which they won! And several users have won prestigious competitions.
