MaxKB

Teams that want an internal AI assistant or customer-facing chatbot built on their own documents, without sending everything to a hosted service, are the natural audience for MaxKB.

MaxKB is an open-source AI knowledge base and assistant platform for enterprises that combines large language models with retrieval-augmented generation.

The RAG pipeline grounds answers in your uploaded content, which cuts down on hallucinations.

You can connect private models or public ones, so the choice of model stays with you.

Beyond question answering, MaxKB has a workflow engine and supports MCP tool use, so an agent can do more than reply with text.

Zero-coding integration lets you place it inside third-party systems without writing glue code.

The OSS Edition is free, but it caps the number of users, applications and knowledge bases.

Larger deployments will run into those limits, and the Pro Edition requires a subscription fee.

Start with the free edition to test whether it fits.
