Tettra review

Tettra is built for teams whose questions start in Slack. Its AI answers questions in DMs and channels, summarizes threads and can mine existing Slack answers into wiki content, so a repeated question becomes a page instead of another message. Inside the wiki, the Scaling plan includes questions and answers, page requests, verification and reports on stale, unowned and public pages, which gives a knowledge owner a clear cleanup list. Permissions cover guest and read-only users, invite-only categories, page locking and groups. The price is $8 per user per month on yearly billing or $10 monthly, with a 10 user minimum, and a 30-day free trial. The weaknesses are in the extras: SSO and SCIM are paid add-ons on Scaling and only included on Enterprise, and the app itself is English only, although content can be in any language.
