Show HN: Patina, an AI that learns your judgment, not just your tasks

Patina, a new AI tool that learns a user's judgment and priorities over time rather than just completing tasks, launched today. The system builds a persistent belief model from Slack exports and other data, tracking context and beliefs while gradually earning autonomy based on accuracy. The local-first, model-agnostic tool provides immediate value from day one by surfacing missed information and prioritizing tasks, with capabilities expanding as it learns the user's judgment.

An AI that learns you — the longer you use it, the less you need to tell it. Your cognitive ceiling isn't set by your intelligence. It's set by your cognitive load. Patina is a persistent extension of your cognition: it holds your context, tracks your beliefs about your world, mirrors your judgment, and improves with every interaction. Day 1: Export your Slack. In 5 minutes, see everything you've missed, forgotten, or let slip. Day 30: It knows your priorities, drafts in your voice, and dismisses noise automatically. Day 90: It predicts what you'd do, catches contradictions across conversations, and operates silently.
