Write in your unique voice, with AI critique
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!

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:…

Writing is hard, and it's tempting to just let AI do the whole thing So I built an Obsidian plugin that keeps AI in its place Highlight a sentence, get some options, pick the one you like Sharpens your writing instead of automating it

I really struggle to keep my notes organised, and often can't make any sense of hand written notes after meetings. I did some experiments with Claude and ChatGPT where I blast random thoughts at them during a meeting or brainstorming session and then have them output a nice document that pulls it all together at the end. It worked incredibly well but it was a bit cumbersome to keep sending messages to the chat and telling the ai each time what to do. So I took the idea and built a tool, it makes it easy to throw random notes and voice recordings (images and document support on the way) and…

Hi HN! Me and my buddy made this in a weekend as an experiment in 1. building something quickly and putting it out there and 2. using AI in an interesting way; in this case a poetry judge. Our “judge” isn’t perfect, but the hope is that at least it’s a relatively fair system that everyone can be sure evaluates their work. Anyway, we wanted to see what the lovely people of HN think of it. Some background on the idea; I like poetry and thought it would be cool if there was a big competition with a large financial incentive that scales with the number of participants. Using AI as a judge allows…

This is the first version of an app idea I had last month as a way to dip my toes into some of the AI APIs. The idea is you can record yourself answering and rehearsing what you'll say to common interview questions, and receive AI feedback on how you did and how you can improve. In the future I may expand into other subject areas, but wanted to scope it to the behavioral interview format for the time being. Super open to feedback and suggestions!

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 trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
