Open-source, self-hosted AI chat and enterprise search over your own docs.

It is self-hosted via Docker/Kubernetes and supports local models, keeping data on your own infrastructure. The core is MIT-licensed and free; an open-core model puts optional enterprise features under a separate license, and the vendor also offers a managed cloud.
