Patina: an AI assistant that learns your judgment and priorities from your Slack history, improving with each interaction over 90 days

Patina ingests Slack exports and builds a persistent belief graph—tracking entities, relationships, and claims with confidence decay—to learn your priorities, communication style, and decision patterns without requiring universal rule configuration.

The system operates across three tiers (deterministic scoring, local LLM via Qwen 3.x or Ollama, and frontier LLM via Claude or GPT-4o), staying local-first with all data stored in ~/.patina/store.db; users can run Tier 1 alone with zero LLM calls and graduate autonomy levels (0–6) earned by accuracy rather than configured.

Day 1 delivers a unified catch-up view; by Day 30 the tool drafts in your voice and dismisses noise; by Day 90 it predicts actions, flags contradictions across conversations, and operates silently—available now via `uv tool install patina` with Apache 2.0 licensing.
