Tettra

Tettra is an internal knowledge base and knowledge-management tool designed to capture company knowledge and make it instantly answerable — especially inside Slack and Microsoft Teams. Teams document processes, answers, and policies in Tettra, and its AI-powered bot (Kai) answers employees' questions directly in chat using that knowledge, so people get answers where they already work instead of interrupting colleagues. Its focus on reducing repetitive questions and keeping knowledge current makes it popular with support, operations, and growing teams.

The platform pairs a simple knowledge base with curation and Q&A workflows. A clean editor and categories organize docs; a Q&A feature lets employees ask questions, route them to experts, and turn answers into reusable knowledge; and content-verification and "knowledge management" features flag stale pages and assign owners to keep information trustworthy. Tettra integrates tightly with Slack (and Teams), Google Workspace, and other tools, and its AI search/bot surfaces the right answer with its source. This combination targets teams that want knowledge to live where work happens.

Tettra serves small and midsize teams — especially support and operations — wanting an easy, Slack-friendly knowledge base. Pricing is per user with tier minimums: a Basic plan around $4 per user/month (minimum 10 users), a Scaling plan around $8 per user/month (minimum 10 users), and a Professional plan around $12 per user/month (minimum 50 users), with a 30-day free trial and ~20% off annually. It competes with Slite, Guru, Notion, and Confluence, differentiating on Slack-native AI Q&A and lightweight knowledge management.
