Show HN: Polaris – Training On-Device AI Agents with Real User Data

[archiv]

I built Polaris to bridge the gap between AI models and real-world user interactions on macOS. It's a Swift toolbox that lets you collect data (screen capture, keystrokes, mouse movements) through official Apple APIs for training and deploying macOS AI agents, with the ability to control your computer programmatically. Still a WIP but looking for feedback!
