EVERYTHING IN ONE AGENT

Not a chatbot. An operator for your support.

Drop a PDF or URL. It learns the rest.

No tagging, no training data. ChatterMate scans, chunks, and indexes your docs and pages automatically — then answers from them with citations.

PERSONALITY

Give your agent a character.

Name it, set its tone, decide when it escalates or asks for feedback — all from an editable prompt.

witty concise empathetic on-brand
HUMAN HANDOFF

Escalates with full context.

Detects frustration, loops in a human, and hands over the whole conversation. No repeating.

MCP TOOLS

Let the agent take action, not just talk.

Connect MCP tools so the agent can look up orders, trigger refunds, create tickets, and call your own APIs — mid-conversation.

Questions, answered.

How fast can I go live?

Under two minutes. Sign up, point it at your docs, and paste one line of code. The agent indexes your knowledge automatically.

What happens when the AI can't answer?

It detects when a customer is stuck or frustrated and hands off to your team with full context — or handles everything itself if you prefer.

Is it really open source?

Yes. The full platform is open source — inspect it, self-host it, and bring your own models. Or use the cloud and skip the ops.

Give your support a brain that never sleeps.

Free for your first 300 chats. Open source forever. Live in minutes.
