Shipped: WACrew

Open-source (Apache 2.0) WhatsApp AI automation for people who serve clients in group chats. I built it to run my own ~200 client groups and DMs.

Every chat lands in one queue sorted by how long it has waited. The AI drafts replies in the owner's own voice, measured from their past messages, and a code-level review blocks robotic phrasing before anything is sent. Delivery is human-paced: seen, typing and pauses, and it stops if the client writes again.

Also ships a client CRM, a live 2D pixel-art office and an MCP server with 36 tools for Claude Code, Codex and Cursor.
