Tettra review (2026): features, pros and cons, and what to check before you buy
Internal wiki and AI Q&A tool built around Slack, with a published per-user price and SSO sold as an add-on.
Our take for buyers
Tettra is an internal wiki and AI question-answering tool built around Slack, with a Google Workspace integration and API access. It fits small and mid-size teams that already live in Slack and want a quick knowledge base. The Scaling plan includes AI answers, the Slack bot and usage analytics. G2 reviewers rate it 4.7 from 159 reviews and praise easy setup and responsive support.
The main buying issue is identity and permissions. SAML SSO and SCIM are paid add-ons on the Scaling plan, and group permissions require the SCIM add-on, so a security-conscious team effectively needs the add-on or Enterprise. Tettra publishes no security certifications, so a formal review will need documents from the vendor.

- Small and mid-size teams living in Slack that want a cheap internal wiki.

What to test in a Tettra demo or trial
Test the Slack bot first, since that is the core use: ask it real questions from your team and check whether the AI answers point to correct pages. Import a sample of your existing docs and see how much work onboarding takes. Check usage analytics on Scaling, and try the Google Workspace integration. If you need permissions by group, ask to trial the SCIM add-on, because group permissions depend on it. Confirm how licenses are counted, as only accepted invites count and Slack-only users are free.
