Tettra

What is Tettra?

Tettra is an AI-powered internal knowledge base built for teams that keep answering the same questions in Slack. Instead of digging through old threads or pinging a colleague, teammates ask a question in Slack or the Tettra app and Tettra's AI bot — named Kai — searches your documentation and replies instantly with an answer plus a link to the source page. When Kai can't find an answer, it routes the question to a subject-matter expert and prompts them to document it, so your knowledge base gets more complete the more it's used. The company was founded in 2015 by Andy Cook and Nelson Joyce in Boston and was acquired by GSoft (now Workleap) in 2023.

The product is organized around a tight knowledge loop: capture content in a simple page editor (importing from Google Docs, Notion, or PDFs), answer questions automatically with Kai, and keep everything accurate with scheduled verification by content owners. A reusable Questions & Answers library stores responses to recurring questions, page requests let anyone flag a gap for an expert to fill, and content suggestions surface stale or unowned pages that need cleanup. Usage analytics show which content gets read and where knowledge gaps remain, which helps teams prove the ROI of documentation work.

Tettra is priced at $8 per user per month on the Scaling plan (10-user minimum, with roughly 20% off on annual billing) and a custom Enterprise tier that adds SSO, SCIM provisioning, custom onboarding, and dedicated support. There is a 30-day free trial but no permanent free plan. The main trade-off in 2026 is scope: Tettra is deliberately lightweight and Slack-centric, so it's fast to roll out and easy for non-technical teams, but it doesn't try to be a sprawling documentation platform like Confluence or a workspace like Notion. For small and mid-size teams that live in Slack and want repetitive questions answered without a heavy setup, that focus is the point.

Pros & Cons
