Knowledge first. Guesswork last.

Gwen is powered by your own Open WebUI and local AI setup. She can use roofing reference knowledge when the chosen model and API route make it available. Always check cited sources and confirm the exact specification.

This is a separate website interface. Existing Open WebUI chat history, uploaded files and Knowledge controls are not automatically mirrored here.
