In plain words
Fixkey is a native macOS application that assists with writing using AI, designed for keyboard-focused workflows. It operates across all macOS applications including Notes, Obsidian, Notion, Gmail, and Slack. Users can select from common prompts or create custom ones using keyboard shortcuts, then fix selected paragraphs with a single key combination. The app supports local model running in beta and emphasizes minimal disruption to writing flow compared to traditional grammar tools.

Demo: https://www.youtube.com/watch?v=sRFOWNpb3U4 Imagine having the CMD+K functionality of Cursor.sh but instead of code you edit natural language. *Introducing Fixkey:* - Native Swift macOS app (no Electron) - Keyboard-centric - Select common prompts with keyboard shortcuts - Press one shortcut to select and fix the current paragraph - Create custom prompts just in time - Works in every application on macOS (Apple Notes, Obsidian, Notion, Gmail, Slack…) - Support for local running models (Beta) *Why not using Grammarly?:* I always feel that traditional grammar correction tools like Grammarly distract me from my flow of writing and thoughts by requiring me to actively select words to autocorrect with my mouse. Fixkey introduces a new mental model for writing; Just hammer down your thoughts and fix your sentence with one shortcut. Using this method boosted my typing speed from 90 to 120 words per minute. Typing feels effortless. I was able to write this paragraph without looking at my screen, just focusing on what I want to say.

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…
