Description: Hey HN! Checkout Flect, a modern AI powered search engine for YouTube podcasts. Describe the content not the keywords.
Flect lets you describe a moment in a podcast and it returns a list of relevant YouTube podcast clips with links to the exact timestamp in the episode. So far I have the top 40 podcasts, 16k episodes, 30k+ hours of content, all searchable by context.
Lex Fridman (3+ years ago) - “one of the things that sucks with podcasts is it’s hard to find stuff…” https://flectai.com/link/?id=677d98e4bb1e4ace8a95598df6cefbb…
Background: I love podcasts but I can never find the clips I’m looking for. Podcasts are exploding in popularity but theres no good search tools out there to find what I’m looking for. I feel like I’m in the pre-search engine age of the internet again but for podcasts. I tried a ton of tools out there but was unable to find anything that worked well. All I could find was naive keyword title searches or AI transcript summarization apps. I want to type in the context of what I remember the hosts talking about and I want it to return a list of relevant clips for me to choose from. Sometimes I don’t know the exact keywords, episode, or even podcast itself. I wanted it to link me to the exact clips I’m looking for and allow me to save or share with friends. Why doesnt this already exist? We deserve a better way to search podcast content.
I’m aware this is a common hobby project idea but nobody seems to have actually built an app that works well yet (as far as I could find, please share if it exists!). YouTube seems to be the most popular way to listen/watch podcasts these days plus it’s accessible and easy to share links, so I started with that.
You can try out a few suggested searches on the landing page or write your own. Flect currently has capabilities to search with arbitrary text, filter for keywords or podcasts, save clips, share, etc.
I’m building this on the side so its built to be extremely lean and efficient. My tech stack: YouTube transcripts, AWS lambda, dbt and Athena for processing data, OpenAI embeddings small, MyScale for vector DB, supabase for auth and backend, nextjs and FastAPI. I’m working on the AI chat feature, taking search to the next level, allowing you to chat with a podcast, summarize, find relevant content, etc.
Would love to hear your thoughts and feedback! Thoughts? Suggestions? I’m all ears!

Description: I often hear people talking about reading old books that stands the test of time. When I picked them up, it’s just so hard for me to get through them. They are hard to really hard to read.
So I made an mobile app where you can read with AI. Select any text/phrase/paragraph, AI will explain in simple terms with the context of the book.

Description: I recently began putting silly posters up on telephone poles, inviting people to text or call me.
I turned a bunch of the voicemails that I’ve received over the past few months into a kind of interactive VM artwork, which you can check out — and contribute to? — by dialling 778-825-0778.
How it works: I’m using voip.ms, who offer a “digital receptionist” or “interactive voice response” (IVR) feature — i.e., a phone tree.
I periodically vet the voicemail recordings that are left, then upload them to voip.ms’s servers, to be used as the outgoing messages of the phone tree. Twice a day on average I re-randomize the database; i.e., I run a script that, through the API, updates the IVR files’ pointers to create a new random order.
What I’ve learned:

Description: What’s the problem, and who is this for?
Writing unit tests can be tedious for some developers. Current tools often fall short because they lack context, leading to inaccuracies, especially in languages like C# and Java. My solution is aimed at developers who want to save time, dislike writing unit tests, need to stick to a strict project structure, or don’t have access to tools like Github Copilot and VS Code extensions.
What sets my idea apart from other AI solutions?
My product focuses on understanding the code context better than existing solutions. It aims to generate tests that align with the current test suite, keeping consistency in patterns, naming conventions, and testing approaches, which existing tools struggle with.
Currently as a WebApp, maybe in future as an IDE extension.

Description: Hello Everyone! I start this project a while ago. It’s about a all-in-one automation tool such as auto clicker, screen clicker, keyboard remapper and more in a single app. This work using AutoHotkey, so what this project do basically is taking input from user then create an AutoHotkey script from that. The goal is to made a software that can do almost all automation task while also can be used as AutoHotkey script manager.
I made this at first for my personal use like gaming because creating AutoHotkey script every single time i play new game is bit inconvenient. But then it start getting audience so i decided to develop it further. AutoHotkey is powerful script to do this and it make my project lightweight that’s why i decided to use it.
Another specialty is use script or remap on specific keyboard or mouse. To do this, i use AutoHotkey wrapper, AutoHotkey Interception by evilC and Interception Driver by oblitum.
I would like to ask opinion and suggestion about this and if you don’t mind, help me test it out. While the basic feature i can say it’s working perfectly fine, i am still not sure about the assign script on specific device feature. As for now i only test it with my keyboard laptop and my mouse and it work (I only have that to test it). Also i would like to ask whether windows show any warning or not (Untrusted source or false positive) because i use pyinstaller to compile it. I use onedir function so i hope it didn’t trigger windows warning. Also does my documentation is clear or it can be improved?
Thank you everyone. I really appreciate your support!

Description: Hey HN,
I’ve been working on SaleSnip, an AI-powered negotiation chatbot that helps websites boost their revenue by enabling customers to haggle for discounts.
The bot engages users during crucial moments - like right before they abandon their cart and offers them personalized deals through a negotiation flow. This approach has been shown to increase conversion rates, recover carts, and even increase average order value with upsells.
I’d love to hear your feedback!

Description: After months of using Google Analytics I realized only about 50% of people accepted my cookie-popup. I had months of incorrect data for my website. I started looking for alternatives and eventually found Plausible, which is great (and open-source). Problem is, I didn’t feel like paying 9$ a month to see the amount of visitors on a website i didn’t even earn anything on, it was just a hobby project.
Eventually I started making my own web analytics. Which actually isn’t that hard. It took me about a month of working on my spare time every now and then. Being GDPR compliant basically means to not save any personal identifiers. At first I thought it would be easy since something like a public IP adress can’t count as a personal identifier right? I was very wrong.
How it works: When a user visited my website I saved the IP and Header for 24 hours. Then if they visited again I checked the combination of IP and Header against the ones saved in my DB. If they were the same I simply added 1 view to my data. If they weren’t the same I added 1 unique daily user and 1 view.
That’s in short how it works. A few weeks later I realized if I had this problem then other would also have it. So I started working on Simplytics.dev. I had to do a lot of new stuff and re-build my code from the ground-up twice. Small things like OAuth was completely new to me and took up a lot of time.
But eventually I got here and just launched something that with the knowledge I have today wouldn’t even take a third of the time recreating today. It’s my first real “Launch” and it feels really good finally creating something AND publishing it. Instead of a montly fee I opted to make it a pay-once service. Right now it’s priced at 49$ but I’ll see how it works out.
If you got any questions on how it works Id love to answer them.

Description: I was frustrated with the complexity and size of existing diagram libraries, so I wrote a new one from scratch. Box-N-Weave.js generates box-and-arrow diagrams from text definitions, with a focus on maintainable technical documentation.
Key features:
- Zero dependencies, tiny footprint (16.2kb gzipped vs 745kb for Mermaid.js)
- Clean separation of diagram content, styling, and animations
- Git-friendly text format that can live alongside your code
- Streamlined syntax for common technical diagrams (architecture, flows, state machines, etc.)
Built-in animation support
Examples: https://box-n-weave-026ffb.gitlab.io/#examples
Repo: https://gitlab.com/andrewfulrich/box-n-weave
I’d love feedback on bugs, the API design, and use cases you’d want to see supported. The goal is to keep it focused on doing one thing well - making it dead simple to maintain box-and-arrow diagrams as code evolves.

Description: Hi HN!
I’ve been building browser automation tools for several years now [0] so when Anthropic came out with Computer Use, I made a Chrome extension to try it out: https://autobrowser.ai
My takeaways from building on Computer Use is that it’s unfortunately not yet reliable for real-world usage and is quite expensive (“go to youtube and play a video about orcas” costs around $0.05). But it’s certainly a promising look at what the future of automation could look like and is really fun to play with.
This was an experiment so it’s free to use with your own API key. Try it out and let me know what you think!

Description: Storytelling is a wonderful human faculty that challenges generative AI, particularly when it comes to long, original works. One thing missing from these discussions is a rigorous definition of good storytelling, a standard that determines whether one story is better than another. Here, our Publishability Index™ (PI) might be useful. It offers a comprehensive criterion for humans to judge a story’s quality. In so doing, it specifies what makes a story not so good, good or great.
The PI is the cornerstone of Bardsy’s efforts to help our members write effectively. It was developed as part of a PhD thesis to evaluate creative writing instruction. We use it to judge Bardsy’s writing contests and in other formative and summative evaluations.
It also provides a more precise language to give more feedback and to discuss the relative merits of stories. Scientifically speaking, it’s an intersubjective criterion designed to increase the reliability and precision of coders’ evaluations. We have had good results concerning intercoder reliability thus far.
In looking at the PI, you’ll see it organizes the conventional wisdom regarding good storytelling into 23 dimensions - covering seven familiar elements, like character and plot. Use the PI as a checklist to evaluate a story. Start at the top and move down, dimension by dimension. Read the criteria for each, first “good,” then “great,” reflecting on whether or not that criteria is present or absent.
To illustrate, the character backstory dimension calls for characters to have a “past that contributes to their identity” to be considered good. If, after reflection, the author determines that this statement applies, they’d check it. If not, they’d move down to the next dimension. If the author checks “good,” they can consider the “great” criterion, defined as “relevant histories that spur individual development and action.” If their character lacks such relevant history, they should seriously consider this omission when revising.
When finished, the author (or judge) can tally the goods and greats to identify a story’s strengths and also find its weaknesses. There’s a tab for notes, too
The PI is intended to be used iteratively, to identify and correct problems with each successive draft until none remain. The name comes from that outcome. Should a story receive 23 greats, we’d consider it to be publishable. More explanation can be found here: https://bardsy.com/forums/blog/the-publishability-indextm-an….
AI seems to have difficulty with this kind of holistic reflection, let alone being able to apply this kind of multi-part standard to creative writing. Our question is whether you would find this useful, either as an adjunct to your own writing or in AI development.
We welcome your thoughts,

Description: Hey fellow hackers!
I’m the creator of the GLB 2 PNG screenshot API: https://www.flowkit.app/glb2png
I aimed to create a fast and easy-to-use API to create screenshots/renderings of 3D models.
Example: https://www.flowkit.app/s/demo/r/rh:-45,rv:15,s:512/u/https:…
This URL renders a 3D model (specified at the end of the link) with:
- -45° horizontal rotation
- 15° vertical rotation
- 512px size
Feel free to tweak these values in the URL and see the results!
Use cases where this could be valuable:
- Configurators: Generate images or thumbnails for different material variations or add-ons (my background).
- Marketplaces: Automate the rendering process for uploaded 3D files.
- IP Protection: Safeguard your 3D files by displaying only rendered images.
- AI Integration: Combine with APIs like OpenAI’s Vision API to categorize or analyze 3D files.
Thanks for reading! I’d love to hear your feedback or suggestions from the HN community

Description: We built a new CSP reporting endpoint service because we couldn’t find existing solutions that met our specific compliance needs at work. We were frustrated with the lack of a clean and efficient dashboard to visualize and analyze policy violations.
So, we decided to take matters into our own hands and built a solution that leverages modern technologies like Bun, Redis, MongoDB, Next.js, and Laravel with Inertia. This tech stack allows us to optimize report collection and provide a smooth user experience.
To use our service, simply set up a report-uri or report-to endpoint on your website. You’ll then receive policy violation reports in our dashboard, enabling you to identify and fix misconfigurations and detect new resources loading on your website.
We’re excited to share our project with the community and eager to hear your feedback and suggestions.

Description: Hello HN!
I was thinking of gift ideas for my special someone. I wanted to create a personal gift that could be both experienced in the moment and treasured forever. A custom word search puzzle, filled with our special memories, inside jokes, and shared moments — seemed like a great idea. I thought hard to come up with the words, used an online tool to generate the puzzle, and put it on a page I designed on Photoshop.
After seeing my partner’s face light up as she discovered each word in that puzzle, I decided to create a delightful app to help others surprise their partners!
Wordamour’s features: (1) Easy-to-use word search puzzle maker (2) 25+ questions to help you come up with words (3) Beautiful, high-quality PDF (A4/A5/Letter) download (4) 100% secure (your data is never stored) (5) 100% free (you can buy me a coffee if you like!)
Try out Wordamour and let me know if it brought a smile to your special someone’s face! :D
