Products that do what I created a self-typing typewriter (and connected it to an LLM) does
Hi HN! I've been tinkering on a programmatically controlled typewriter. I've got a working prototype and it's been a lot of fun to play with. Of course I connected it to ChatGPT so I can chat with it, and I also have it acting as a clock, but it doesn't just type out the time. It writes a poem about the time. I'm posting this to gauge interest in purchasing one. It's all handmade, so I can't scale it up, but if enough people are into it, I might make a small batch. Or maybe sell it as a kit for the DIY crowd. Anyway, just wanted to put it out there and see what you all think. Thanks for…

Hi, I'm a high school teacher from Australia and I've built what I'd like to think is a pretty nifty ChatGPT powered presentation tool for teachers. I'd love it if you could have a look at it and give me some of your feedback. I don't think there's much overlap with the HN crowd and school teachers, but I've been coming here for many years and thought I'd post here and see what you all think. Check it out if you have a minute and I'd be super happy to hear your feedback too. https://www.slidehero.ai/ You can jump in and have a play with the tool all you like ;) Cheers, Eli

I blew off a bunch of "serious" side work last month and built a tiny little embeddable editing tool that I've wanted to have for Ars Technica since, well, the beginning of internet time. It lets any random user make edit suggestions for writers/editors to consider and act on. I think it's pretty cool and it's gotten some good use over the last few weeks. Of note, it's uses a single-field signup form. Edit administration is currently email based, so all it needs is an email address to get people going. I'm sure I'm not the only person to ever do this, but I basically just turned it on one…

This is our entry in the "spontaneous event creation" ring. I'd love to hear what HN readers think!

I'm trying to get the motivation up to actually finish building out a "real" product, and I found myself needing a "win" to keep my momentum up. So, I hacked out a little one sentence journal app last night. I experimented with a few UI things (e.g.., the autosaving of the sentence for today and so on), so it was a good learning experience also. You can check it out at: http://osod.im

Hi HN, After watching a lot of Show HN's here, it's finally my turn to show something. This is the first real project I have shipped, so it is extra special to me. For those who will inevitably ask why I made yet another mockup editor I covered it on our blog (http://blog.mocktailsapp.in/why-build-yet-another-mockup-editor-tm). Not all the features mentioned in that post have been implemented yet. As such Mocktails is pre-beta software and very minimal. It does not even have user accounts or any actual server side component at all for that matter (yet)! Our intention is to build Mocktails…

I've been wondering how I could use LLMs to help me write, without taking my own voice away. I arrived at a workflow where the AI has strict instructions not to give me any text, just to give me tips, but it was clunky to see which parts of the text the critique referred to. To solve it, I made Lucid. I made it mostly for myself, but I added a "bring your own key" system for others to use it. I hope you like it!

I’m specifically looking for a tool a user shared on here that facilitated writing for content by scrolling up and disappearing text as new text was inputted. I believe it was a HTML/JSS only solution - a small personal project. I’ve done a lot of focused searches, but haven’t been able to find this comment. That said, I love these sorts of projects. I know they’re a self-indulgence and often a distraction. I’m celebrating that for a moment, personally. Please share your favorites writing tools, the smaller and more personal the better.

Had this idea recently and just had to get it out of my head and into a (super quick and dirty) prototype. It's like Letterboxd but for anything, and with a simpler rating system you don't have to sweat about.

Hi all, I threw together a small prototype I am calling “Notepad.ai”. A new take on UIs for interacting with LLMs. While I enjoy using LLM’s in the chat format I wanted to see what it would be like to do it in a more long form style. It let’s you write in a pretty free form, much like Window’s Notepad, but you can choose to hit ctrl+[ to analyze the text with a preset prompt of your choosing. It has a few other small features. It’s WIP and very experimental. I would appreciate any feedback or thoughts. Video: https://youtu.be/ntdlgFmSxQY Live Demo:…

Just wanted to make my first post about something interesting I've been working on for some time. Any ideas/suggestions for new hardware or software I should try out are welcome, though I will only have time for a major overhaul in a month or two where I want to redo and document everything a bit better than how it is currently. Hope this can inspire someone to start their own homelab or give some ideas to already existing ones!

Recently, I found myself having to read the book "C++ primer" and I just couldn't do it. Maybe my attention span is too little now with Claude and Codex, maybe I'm lazy... but I just couldn't get myself to focus. While reading, I needed something to do. I wanted to talk to the text, I wanted to leave notes, I wanted to use to use my keyboard to quickly flip through pages. The only good available option on a Mac was "Preview" and it was ok, but definitely not there. So I built Quincy primarily for myself. With it you can - "Talk" to the page you're reading, create a quiz about the page, and…

I’ve been playing around with local LLMs for the past couple of months and decided to build something that can run on an iPhone. It’s a universal app built with SwiftUI and the excellent ggml library. The model is an SFT fine tuned and 4 bit quantised version of the RedPajama-INCITE-Chat-3B-v1 OSS LLM. It works reasonably well on recent-ish (~3 year old) iPhones, iPads and Macs. It was launched on the App Store yesterday[1] and Product Hunt today[2]. It seems to be reasonably ok at natural language interactions, but given its size, does pretty badly at coding and reasoning. Also, it…

Hey HN, I am making an 8-Bit CPU in Logisim and blogging about it.t's nothing fancy, really simple, unoptimized dumb CPU for sake of learning. I am no electrical engineer, I am just a self-taught dude who has programming as a hobby and wanted to dive deeper into abstractions. So here it is, so far I wrote 2 parts: [links redacted] I welcome any and all critique and feedback, as I can be wrong about everything for sure.

Well HN, I've finally produced something I think is worthy of sharing, but I didn't do it "in a weekend". Yeah, it's an iOS puzzle game. And yeah, it's a game I built because I wanted to play it rather than based on market research, so all this sort of makes it the antithesis of a popular HN post. But whatever. Still hoping for some of that patented (har har) expert HN feedback. Critique any part of it except the music. Also, PM me for upgrade codes, or I can post some here if there's any interest. Download (it's free):…

After reading gwern’s post two days ago about LLM Daydreaming [0], I wanted to just see how it would behave. I grabbed the top vital article titles from wikipedia [1] and made a simple next js app to try the prompt in a loop. It was pretty interesting to see the connections made between concepts. Happy to host this if people find it useful! [0] https://gwern.net/ai-daydreaming [1] https://en.wikipedia.org/wiki/Wikipedia:Vital_articles

I created a small typing game. Would love to get some feedback on it. What can I improve? Are there any features you're missing? Are you having fun playing it? I certainly did have fun :)

Hey HN, I wrote a short book about the fundamental aspects of Clojure. The target audience is programmers with at least minimal experience who want to learn how to express solutions in Clojure (and perhaps in LISP, generally). If the price is a bit too steep for you, send me an email (address in bio), and I'll provide a discount coupon. If you can't afford it all, and believe the material may help you for studying or interview preparations, I can send you a free copy.

Hi HN! Writing has been a big part of my life for the last few years. It's helped me make sense of the world around me through journaling, and my blog and technical books have made wonders for my career as an engineer. Something I've always been missing is an online community where I can practice my skills and learn from other aspiring writers. I built Tavern, hoping to solve my own problem. Its main concept is that every Monday everyone in the app gets asked the same writing prompt and you have seven days to submit your answer. You can look at what others have posted, but only after you've…

Just finished some work involving ChatGPT when I felt strong Tolkien nostalgia, so asked it to write a song in the style of Hobbit, the result was amusing, so what the heck, here it is: > Write a short song in the style of Tolkien's Hobbit that tells of a skilled programmer creating artificial intelligence Verse 1: In the land of code and screens, Where the bits and bytes do gleam, There lived a programmer so wise, With knowledge and skills that did surprise. Chorus: Creating AI, a masterpiece, A mind so bright, a true release, Bringing forth a new dawn, Of intelligence beyond what's gone.…

Hi HN! In the last couple of weeks I've been working on Cranki: Cranki = Crosswords + Anki. (It's a stupid name tbh, haha) I like doing crosswords in Spanish (to learn vocab) but none of the apps out there allowed me to use my own list of words that I come across. So I built one instead. It's entirely client-side. No server, no database, no accounts, etc. Your words and stats are stored in local storage. I built this for myself but let me know if you like it!
