TextAI – Native SMS AI assistant for individual and group chats
Hey HN community! Like many of you, I spend most of my day in text conversations. One day I found myself switching between group chats and various AI apps, and thought, why can't AI just live where we already chat? So I built TextAI. It's an AI that works right in your SMS app. No new app to download, no platform to learn. Just text +15626840069 to start chatting or add it to any group chat! The tech and stack details: - Native SMS/MMS integration with context management across conversations - Handles multiple participants, learns group preferences, and scales for concurrent chats -…
What it does
In the maker’s words, at launch
Hey HN community! Like many of you, I spend most of my day in text conversations. One day I found myself switching between group chats and various AI apps, and thought, why can't AI just live where we already chat? So I built TextAI. It's an AI that works right in your SMS app. No new app to download, no platform to learn. Just text +15626840069 to start chatting or add it to any group chat! The tech and stack details: - Native SMS/MMS integration with context management across conversations - Handles multiple participants, learns group preferences, and scales for concurrent chats - Able to converse in multiple languages - Built with Twilio on top of a foundational LLM model, plus building my own domain logic on top Some cool things people have used it for: - A group of my friends used it to plan a weekend trip to Las Vegas last week. It was their first time there. They used it to get suggestions on the must-do activities, casinos to play at, and finding restaurants that worked for vegetarians and meat lovers. - A high school student showed the power of AI and started a group chat with their grandpa! - my personal fav - A couple who used it to find new hiking trails around where they live without arguing for their preferences I built this because I believe AI should be accessible through existing communication channels, not locked in new apps. It should be accessible to all, and frankly, it's important to keep things simple. Hope you find it useful, and I would love your feedback, the good and the bad! Thank you for reading!

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…

- TITetris in a PDF▲1,289
I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…
