ChatterMate is an open-source AI support platform built for teams who want automation without handing their conversations to a third party. It reads your existing docs, PDFs and web pages, indexes them automatically, and answers customer questions around the clock with citations back to the source material. Setup is a single line of embed code.
The whole stack is Apache-2.0 licensed and self-hostable with Docker, and it is not tied to one LLM vendor: OpenAI, Anthropic Claude, Gemini, Mistral, xAI Grok, DeepSeek and Groq are supported, plus any OpenAI-compatible endpoint, so you can point it at a local model via Ollama, vLLM or llama.cpp and keep conversations on your own infrastructure — a practical alternative to Intercom, Zendesk Chat, Tidio and Drift.
Beyond chat: one shared inbox spanning nine channels, one-click handoff with full context, a no-code workflow builder, AI ticketing, lead capture, a help center, and integrations for Slack, Shopify, Jira, REST API and MCP tools.
