Tettra
AI-powered internal wiki that answers questions from your docs.
About
Tettra is an internal knowledge management system that gives teams a central, searchable wiki for processes, policies and how-tos. Its standout feature is Kai, an AI assistant that lives in Slack and Microsoft Teams: employees ask questions in chat, and Kai answers from the team's documented content with links back to the source pages. When it cannot find an answer, it routes the question to the right expert, which captures tacit knowledge instead of letting it evaporate in threads.
The platform fights documentation decay, the reason most wikis die, with a verification system where subject-matter experts periodically re-approve pages and a stale-pages report that flags outdated content. Teams can build pages in the native editor or import from Google Docs, Notion and PDFs, use templates for onboarding guides and SOPs, and manage knowledge gaps through a Q&A and page-request workflow. An experimental REST API is available on Scaling and Enterprise plans.
Tettra holds a 4.7 rating on G2 across 161 reviews and offers both free and paid tiers, with paid plans reported around five euros per user per month. It is aimed at startups and mid-size teams that live in Slack; larger enterprises with complex knowledge governance needs may find its simplicity limiting, which reviewers note as the main tradeoff.
