Chatty is an open-source, production-grade AI customer support platform. It unifies web chat, real-time voice, document grounding, and an MCP server under a single deployment.
- Embeddable Chat Widget: Drop-in web component with session persistence, lead capture, and custom theme overrides.
- Real-Time Voice Agent: Sub-500ms conversational audio powered by LiveKit WebRTC and speech-to-speech pipelines.
- Document RAG Engine: Instant knowledge grounding via PDF, TXT, DOCX, and live website crawling.
- Model Context Protocol (MCP): Native FastMCP server providing external AI coding tools direct access to bot auditing and knowledge management.
- Conversational Actions: Automated calendar booking (Google Meet and Zoom) and webhook dispatch.
- Hybrid Self-Hosting: Deploy application containers on your own host while keeping Supabase Auth and Postgres managed.
