Tettra review

Tettra solves a specific problem: the same internal questions asked again and again in Slack. Its Scaling plan, at $8 per user per month on yearly billing or $10 monthly with a ten user minimum, includes an AI bot that answers in Slack DMs and channels, summarizes threads and can mine existing Slack answers into pages. It also has question and answer flows with page requests, AI page tagging and FAQ generation, Google Workspace integration, usage analytics and API access. For upkeep it offers verification plus reports on stale, unowned and public content, which help an operations lead keep the knowledge base honest. The limits: there is no free plan, the seat minimum means the real starting cost is $80 a month, SAML SSO and SCIM are paid add-ons below Enterprise, and teams that do not use Slack lose much of the appeal. For Slack-centric companies, it turns repeat questions into documented answers with little effort.

Who it is for
