Willow – local-first AI stack, phone reads desktop KB over LAN, no cloud relay

A running Willow on Termux sent a signed command to a desktop running Willow on Linux. The response came back in under a second - 70,000 knowledge atoms, live system status, no Discord, no Telegram, no API call to a third party. Willow is a full local-first AI stack: Postgres/SQLite knowledge graph that persists across sessions and models, 40+ MCP tools, a skill system that works with any LLM (Ollama is the default, cloud keys are optional addons), and a LAN command server - HMAC-SHA256 auth, shared token, ~100 lines of Python. The knowledge graph is yours.
