Tettra review and pricing

Slack-native team wiki with knowledge requests and verification workflow.

By Tettra · Founded 2015 · Boston, MA · private

Tettra is the Slack-native wiki, founded 2015 in Boston and built around the conceit that knowledge requests should start where the team already lives. The product surfaces inside Slack as a bot that captures questions, routes them to subject-matter experts, and converts answers into wiki pages with a lightweight verification workflow. Strengths: tightest Slack integration in the category, lightweight knowledge-request and verified-answer workflow that fits how distributed teams actually ask questions, transparent flat per-user pricing, clean editor, and a focused product that has not chased scope creep. Trade-offs: smaller vendor footprint than Notion or Confluence (procurement pushback at large enterprises), no doc-database hybrid features, AI features lighter than category leaders, integration depth outside Slack is narrower than Slab or Notion, and the brand sits in the long-tail of buyer awareness next to Notion and Confluence.

Visit Tettra Vendor pricing Compare to Slab
Best for

Distributed and remote-first teams that already live in Slack and want a wiki that meets them where they are. Particularly strong for support, customer-success, ops, and people teams of 20 to 500 employees that ask and answer questions inside Slack channels.

Worst for

Teams not on Slack (Notion or Slab better), teams wanting a doc-database hybrid (Notion or Coda better), large enterprises needing deep admin and audit (Confluence better), or teams wanting the most aggressive AI features (Slite or Notion better).

    Tettra AI answers launched inside Slack
    AI-powered answers from the wiki surfaced inside Slack; useful for teams already routing knowledge requests through Slack, lighter than Notion AI in capability.

    Steady customer growth in support and customer-success segment
    Customer references across support, customer-success, and ops teams; positions Tettra as the focused Slack-native wiki for distributed teams.
Vendor Trust is scored independently of product quality. A great product from an unfair vendor still earns a low trust score.
