Chatty by PersonaliAI
Open-source AI agent trained on your store and content.Answers customer questions, captures leads, and books meetings on website, WhatsApp & Slack.
Chatty is an open-source, self-hostable Zendesk and Intercom alternative for stores and modern businesses that need autonomous AI customer support with human takeover, WooCommerce sync, and calendar scheduling.
Run the application containers on your own host while keeping Supabase Auth,
Postgres, Storage, and Realtime managed. The same deployment contract works on
a VPS, Railway, Render, or another Docker host without touching the live
Supabase project.

Why Chatty
Every hosted chatbot SaaS charges per-seat or per-message and holds your conversation data. Chatty is open-core: run it yourself for free, or use Chatty Cloud - our own hosted version of this exact repo, if you'd rather skip the ops work. Either way you get the same feature set - streaming chat, RAG over your own documents, meeting booking, lead capture, WhatsApp/Slack channels, and a full MCP server so an AI agent can run the whole dashboard for you.
