Show HN: Jq-Like Tool for Markdown
There have been a few times I wanted the ability to select some text out of a Markdown doc. For example, a GitHub CI check to ensure that PRs / issues / etc are properly formatted.<p>This can be done to some extent with regex, but those expressions are brittle and hard to read or edit later. mdq uses a familiar pipe syntax to navigate the Markdown in a structured way.<p>It's in 0.x because I don't want to fully commit to the syntax being stable, in case real-world testing shows that the syntax needs tweaking. But I think the project is in a pretty good spot overall, and would be interested in feedback!
Show HN: Japanese City Name Generator – Using a Simple 3-Layer MLP
I trained and deployed my first model: a Japanese city name generator using just a 3-layer MLP under the hood. It runs in the browser fully locally on the onnx runtime.<p>Trained on <2,000 real Japanese city names, what's interesting is that on this simple task the simple MLP performed better than more complex models which tended to overfit and generate existing names.
Show HN: BookWatch – Animated book summaries for visual learners
Hey HN! I’m Miran Antamian, founder and CEO of BookWatch, and I’m thrilled to introduce BookWatch.com. The first AI-powered Visual Library for learners who hate reading but love growing.<p>After 1.5 years of building, 65,000+ mobile app users, and countless animated summaries, we’re launching our New Web App to make learning even more effortless.
The Problem: Visual Learners Can’t Learn from Books in Text or Audio Formats
Did you know that 65% of people identify as visual learners? Yet most book knowledge remains trapped in text format. Many of us want the wisdom of great books but struggle with:
- Finding time to read entire books
- Maintaining focus through hundreds of pages
- Remembering key concepts without visual reinforcement
- Traditional reading is slow, boring, and leaves millions of learners behind.<p>Our Solution: Learn by Watching, Not Reading<p>BookWatch uses proprietary AI technology to transform non-fiction bestsellers into animated video summaries that capture the core ideas in a visually engaging format.<p>Some animated book summaries you might like:<p>- Hackers and Painters by Paul Graham: <a href="https://www.bookwatch.com/videos/aGtpl1QLtyzN6JlqRze7" rel="nofollow">https://www.bookwatch.com/videos/aGtpl1QLtyzN6JlqRze7</a><p>- Zero to one by Peter Thiel: <a href="https://www.bookwatch.com/videos/rSvhERHHBoF8bpTlXnyi" rel="nofollow">https://www.bookwatch.com/videos/rSvhERHHBoF8bpTlXnyi</a><p>- The lean startup by Eric Reese: <a href="https://www.bookwatch.com/videos/dTwT3JdLWvpAsOVGbePa" rel="nofollow">https://www.bookwatch.com/videos/dTwT3JdLWvpAsOVGbePa</a><p>- Blitz Scaling by Reed Hoffman and Chris Y: <a href="https://www.bookwatch.com/videos/ogoFpks8aRGn8OgmKP2F" rel="nofollow">https://www.bookwatch.com/videos/ogoFpks8aRGn8OgmKP2F</a><p>What Makes BookWatch Special?<p>(1) AI-Powered Personal Book Expert
Every video comes with an AI expert that knows everything about that specific book. Ask how to apply concepts to your unique situation: "How can I use these ideas to improve my startup?" or "How would this apply to my leadership role?". Our AI expert will give you specific advice based on the book on how to apply it in your life or business situation.<p>(2) Smart Note-Taking System
Our one-click note system captures what's being said at that exact moment in the video. No need to pause or get distracted - just click and continue watching! Review and organize your notes later.<p>(3) AI Book Recommendation Engine
Don't know where to start? Tell our AI what you want to learn ("I want to be a better public speaker" or "I want to be more productive" or “I want to learn b2b sales”), and it'll recommend the perfect books from our library.<p>(4) Progress Tracking & Gamification
Stay motivated with achievement badges, learning streaks, and a visual representation of your growing knowledge base. See how many days have you been learning and which books helped you more.<p>Business Model<p>We've adopted a freemium approach:

Show HN: Willpayforthis.com – Ideas people will pay for
Ah, there's a dumb easy hack to figure out what ideas people will pay for. Search "I'd pay for" on Twitter and you'll find hundreds of posts from people talking about pain points and products they'd pay for to solve them.<p>Do this enough and you realize you have to filter through a lot of slop. slop. slop.<p>I created willpayforthis.com to accumulate high signal, high quality posts and save you some time.<p>I love thoughts from the community on how I can make it better, save you time, and help you work on the best ideas.

Show HN: I built an AI voice agent for Gmail
Hello again, HN! I’ve been using my DSL to create new voice experiences.<p>I’ve made an AI-powered email client for Gmail that you talk to, using your microphone. (I <i>highly recommend</i> using earbuds or headphones! Or the best is with Ray-Ban Meta glasses.)<p>Some fun things: Every user’s agent has a slightly different personality. You can train it by asking it to remember things for next time. And it presents some generative UI while you use it.<p>This is the first time I’m showing this publicly. I’d love your feedback! What works well, and what doesn’t?<p>I previously did a Show HN for ‘D&D meets Siri’: <a href="https://news.ycombinator.com/item?id=41328794">https://news.ycombinator.com/item?id=41328794</a>. I’m thinking of releasing the framework/DSL that I’m using to craft these experiences. Would that be interesting? Would you want to build voice apps?

Show HN: One year of bewCloud (a simpler Nextcloud alternative)
It's been over a year since I started working on bewCloud and 11 months since I posted the first Show HN [1].<p>Many things changed (check the commits [2] or the video updates [3] for more details), we've got one recurring sponsor, and recently the GitHub repo [4] passed 400 stars! We also just launched a new option to buy access to a managed instance.<p>If you have any suggestions, comments, or recommendations, I'd love to hear about it.<p>Thank you for your attention and kindness. I really appreciate it!<p>[1] <a href="https://news.ycombinator.com/item?id=39726172">https://news.ycombinator.com/item?id=39726172</a><p>[2] <a href="https://github.com/bewcloud/bewcloud/commits/main/">https://github.com/bewcloud/bewcloud/commits/main/</a><p>[3] <a href="https://www.youtube.com/@bewCloud" rel="nofollow">https://www.youtube.com/@bewCloud</a><p>[4] <a href="https://github.com/bewcloud/bewcloud">https://github.com/bewcloud/bewcloud</a>
Show HN: Slime OS – An open-source app launcher for RP2040 based devices
Hey all - this is the software part of my cyberdeck, called the Slimedeck Zero.<p>The Slimedeck Zero is based around this somewhat esoteric device called the PicoVision which is a super cool RP2040 (Raspberry Pi Pico) based device. It outputs relatively high-res video over HDMI while still being super fast to boot with low power consumption.<p>The PicoVision actually uses two RP2040 - one as a CPU and one as a GPU. This gives the CPU plenty of cycles to run bigger apps (and a heavy python stack) and lets the GPU handle some of the rendering and the complex timing HDMI requires. You can do this same thing on a single RP2040, but we get a lot of extra headroom with this double setup.<p>The other unique thing about the PicoVision is it has a physical double-buffer - two PSRAM chips which you manually swap between the CPU and GPU. This removes any possibility of screen tearing since you always know the buffer your CPU is writing to is not being used to generate the on-screen image.<p>For my cyberdeck, I took a PicoVision, hacked a QWERTY keyboard from a smart TV remote, added an expansion port, and hooked it all up to a big 5" 800x480 screen (interlaced up from 400x240 internal resolution).<p>I did a whole Slimedeck Zero build video ( <a href="https://www.youtube.com/watch?v=rnwPmoWMGqk" rel="nofollow">https://www.youtube.com/watch?v=rnwPmoWMGqk</a> ) over on my channel but I really hope Slime OS can have a life of it's own and fit onto multiple form-factors with an ecosystem of apps.<p>I've tried to make it easy and fun to write apps for. There's still a lot broken / missing / tbd but it's enough of a base that, personally, it already sparks that "programming is fun again" vibe so hopefully some other folks can enjoy it!<p>Right now it only runs on the PicoVision but there's no reason it couldn't run on RP2350s or other hardware - but for now I'm more interested in adding more input types (we're limited to the i2c TV remote keyboard I hacked together) and fleshing out the internal APIs so they're stable enough to make apps for it!
