An internal wiki that works inside Slack and uses AI to answer team questions.
About Tettra
Tettra keeps internal knowledge in a wiki and brings it to the place employees already ask questions: Slack and Microsoft Teams. People can request an answer and get one from the wiki, or have the question routed to an expert.
Its AI answers from existing pages and suggests new content when the same question keeps coming up. Verification workflows keep pages from going stale.
Tettra has paid plans per user with a trial. It suits teams that want a lightweight knowledge base tied to chat.
