I made a Chrome Side Panel note to beat context switching
Hey HN I read and research multiple things, both for work and personal curiosity. But I realized that in doing so, I have to frequently switch among many reading tabs and note-taking pages, which breaks my reading flow. That's why I teamed up with my friends to build Saner.ai Chrome Extension. It’s a side panel note that appears across tabs, and we can toggle it on and off whenever we like. Also, we can highlight any text and then use keyboard shortcuts to save it along with its URL. This has made my reading and research experience smoother :) I hope it will be helpful to people like us out…
In plain words
Saner.ai is a Chrome extension that keeps a persistent side panel note accessible across all tabs, helping researchers and readers avoid constant context switching. Users can highlight text and save it with its source URL using keyboard shortcuts. The tool is designed for anyone who manages multiple reading and research tasks simultaneously.

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…
