Show HN: Struct – A Feed-Centric Chat Platform
Hi HN! I’m Jason, a product designer at Struct Chat.<p>At Struct, we're frustrated by the clutter, distractions, and inefficiencies plaguing existing chat platforms like Slack and Discord.<p>We've built a radical new chat platform that leverages threads, feeds, and AI to help alleviate these problems, and give you back more time in your day.<p>Struct uses a thread-first approach to keep conversations on-topic. It applies AI-generated titles and summaries to help you decide what's worth your attention. Threads are then organized in a real-time feed, keeping all your conversations up-to-date and at the ready, eliminating the need for channel hopping.<p>Comprehensive search tools make finding things a breeze, and Strucbot, our AI assistant can answer questions based on what it’s learned from prior threads. It can even proactively respond when it notices repeat requests, providing quick answers so you don’t have to. Structbot is fully GPT-4 enabled, so you can riff with Chat GPT and your peers (generate code, ask questions, all the good stuff) without ever switching apps.<p>Struct is available on Linux, Windows, Mac, and even works as a Slack interface. Give us a try and let us know what you think.

Show HN: Workout Tracker – self-hosted, single binary web application
I tried some web tools to track my workouts (specifically, running); some (like FitTrackee) came close, but I always found annoyances. So I decided to build my own. Specifically geared towards distance-based workouts, such as walking, running or cycling.

Show HN: I made an app to use local AI as daily driver
Hi Hackers,<p>Excited to share a macOS app I've been working on: <a href="https://recurse.chat/" rel="nofollow">https://recurse.chat/</a> for chatting with local AI. While it's amazing that you can run AI models locally quite easily these days (through llama.cpp / llamafile / ollama / llm CLI etc.), I missed feature complete chat interfaces. Tools like LMStudio are super powerful, but there's a learning curve to it. I'd like to hit a middleground of simplicity and customizability for advanced users.<p>Here's what separates RecurseChat out from similar apps:<p>- UX designed for you to use local AI as a daily driver. Zero config setup, supports multi-modal chat, chat with multiple models in the same session, link your own gguf file.<p>- Import ChatGPT history. This is probably my favorite feature. Import your hundreds of messages, search them and even continuing previous chats using local AI offline.<p>- Full text search. Search for hundreds of messages and see results instantly.<p>- Private and capable of working completely offline.<p>Thanks to the amazing work of @ggerganov on llama.cpp which made this possible. If there is anything that you wish to exist in an ideal local AI app, I'd love to hear about it.

Show HN: AI dub tool I made to watch foreign language videos with my 7-year-old
Hey HN!<p>I love watching YouTube with my 7-year-old daughter. Unfortunately, the best stuff is often in English (we're German). So I made an AI tool that translates videos directly, using the original voices. All other sounds, as well as background music, are preserved, too.<p>Turns out that it works for many other language pairs, too. So far, it can create dubs in English, Mandarin Chinese, Spanish, Arabic, French, Russian, German, Italian, Korean, Polish and Dutch.<p>The main challenge in building this was to get the balance right between translating the original meaning and getting the timing right. Especially for language pairs like English -> German, where the target ist often longer than the source ("bat" -> "Fle-der-maus", "speed" -> "Ge-schwin-dig-keit").<p>Let me know what you think! :)

Show HN: AboutIdeasNow – search /about, /ideas, /now pages of 7k+ personal sites
Hi HN!<p>It’s hard to find interesting people to work with on your ideas.<p>Our solution: index the /about, /ideas, /now pages of 1000s of personal websites. There are thousands of cool personal sites out there, with amazing ideas on them, but there’s nowhere to easily search through. So we built a simple site that indexes 7k+ personal sites [0]. We were inspired by Derek Sivers’ Now page movement [1] and other IndieWeb directories [2], but we figured that it would be more useful if we:<p>* Let you search directly across personal sites without having to visit them<p>* Take the content from 3 specific pages, /about, /now and /ideas, to structure everything<p>* Define /ideas pages as a space to articulate things you want to work on<p>We hope this’ll be a cool place for people to find others to collaborate with - would love your feedback. If you’d like your site to appear at the top, add it via the form and add a last updated date of today (any format). It’s completely open source (MIT) and open to contributions [3]!<p>Peter & Louis<p>[0] gathered from: 1) <a href="https://nownownow.com" rel="nofollow">https://nownownow.com</a> and similar sites 2) checking all HN posts since 2020 with more than 100 upvotes<p>[1] <a href="https://nownownow.com" rel="nofollow">https://nownownow.com</a><p>[2] <a href="https://personalsit.es" rel="nofollow">https://personalsit.es</a><p>[3] <a href="https://github.com/lindylearn/aboutideasnow">https://github.com/lindylearn/aboutideasnow</a>

Show HN: Reverse-Engineering a Switch Lite with 1,917 wires
Hey Hackers. This is a project I solo-developed that turns completed PCB assemblies into an easy to use boardview with some accompanying boardscans. There are lots of easier and better ways of doing this, but this is an experimentation to do it as cheaply as possible, with the highest quality and lowest chance of errors. The technical details are in the link.<p>Most public boardviews are almost entirely the result of industrial espionage, other than a few encrypted subscription based software platforms that provide extensive access. The process output is released as donationware, as my main concern is that even released as a low-cost purchase, there is a very strong culture to share this type of information at no cost. I would like to have a more sophisticated suggested donation system adaptive to user country, but I wasn't able to find a good solution.<p>In terms of 'good startup ideas', I don't think this is one of them. The very high level of soldering skill required makes it difficult to scale, and the prevailing piracy culture makes it challenging to monetize. My main advantage is that costs are very low now that I have the entire thing working. Other than forge ahead at a loss and hope for the best, or to pivot hard leveraging the imaging technology, I'm not sure what other options I have. It feels too complicated and repetitive for shoft-form video content. If you have any feedback, questions, suggestions, etc., I'd love to hear them.

Show HN: OK-Robot: open, modular home robot framework for pick-and-drop anywhere
Hi all, excited to share our latest work, OK-Robot, which is an open and modular framework to perform navigation and manipulation with a robot assistant in practically any homes without having to teach the robot anything new! You can simply unbox the target robot, install OK-Robot, give it a "scan" (think a 60 second iPhone video), and start asking the robot to move arbitrary things from A to B. We already tested it out in 10 home environments in New York city, and one environment each in Pittsburgh and Fremont.<p>We based everything off of the current best machine learning models, and so things don't quite work perfectly all the time, so we are hoping to build it together with the community! Our code is open: <a href="https://github.com/ok-robot/ok-robot">https://github.com/ok-robot/ok-robot</a> and we have a Discord server for discussion and support: <a href="https://discord.gg/wzzZJxqKYC" rel="nofollow">https://discord.gg/wzzZJxqKYC</a> If you are curious what works and what doesn't work, take a quick look at <a href="https://ok-robot.github.io/#analysis" rel="nofollow">https://ok-robot.github.io/#analysis</a> or read our paper for a detailed analysis: <a href="https://arxiv.org/abs/2401.12202" rel="nofollow">https://arxiv.org/abs/2401.12202</a><p>P.S.: while the code is open the project unfortunately isn't fully open source since one of our dependencies, AnyGrasp, has a closed-source, educational license. Apologize in advance, but we used it since that was the best grasping model we could have access to!<p>Would love to hear more thoughts and feedback on this project!
