Tettra

Tettra is a web-based internal knowledge base and knowledge management platform for teams that want organized documentation and AI-assisted answers to repetitive questions, especially in Slack.

Key capabilities include:

• AI Answers in Slack: an AI bot can respond to questions in channels and DMs, and support thread summarization when teammates ask repeat questions.
• Wiki-style knowledge base: create pages with a built-in editor, keep unlimited storage and version history, and use page requests to capture missing documentation.
• AI-assisted curation: generate FAQs, apply AI page tagging, and maintain trusted content with Q&A workflows.
• Integrations and access: connect Google Workspace (including training from Google Docs); usage analytics and API access are available on Scaling+ plans.

Pricing: Paid. Basic starts at $4/user/month (annual, 10-user minimum), Scaling at $8/user/month (annual, 10-user minimum), and Enterprise starts at $7,200/year (50-user minimum). 30-day free trial is available for Basic and Scaling.

Notable for combining a curated internal wiki with an AI Slack bot that answers common questions where teams already work, plus Enterprise options such as SSO, , and custom integrations.
