About Tettra

Tettra is a hosted internal knowledge base for small and growing companies, built on the idea that most wiki traffic is people asking the same questions again. Teams write pages and Q&A entries, and Tettra's AI bot answers questions asked in Slack channels and DMs from that content, routing anything it can't answer to the right expert. Page owners get reminders and reports about stale or unowned content, and suggested edits from teammates can be approved quickly, which helps keep things accurate without a dedicated knowledge manager. A Google Workspace integration and an API are available on the main plan. It is a focused tool: there are no databases or project features, and its value is highest for companies that live in Slack. Pricing is per user per month with a minimum seat count and a free trial, and larger plans add onboarding help and custom reporting. It runs in the browser and inside Slack.

Best for: Slack-centric teams tired of answering the same internal questions.
