PowerChat

PowerChat is an experimental, local-first chat app for exploring how people and AI agents can share a working channel. Built with SolidStart, PowerSync, Supabase Postgres, Drizzle, and Mastra, it provides real-time channels, offline-capable local SQLite writes and sync, and @mentions that trigger agents and persist streamed replies. Each channel also has a server-side workspace whose file metadata is synced into the UI, with raw text-file inspection. It is a prototype rather than a production service: anonymous cookie sessions and the current feature set exist to test collaborative agent workflows, not to offer a finished hosted product.
