Question Base vs Tettra (2026): which should you pick?

Pick Question Base if

• Fits if your team asks the same questions in Slack all day and your docs are already in Confluence, Drive or Notion
• Works for departments that can commit to a yearly plan

Look elsewhere if

• Skip it if you want a free plan or a self-serve trial, as there is neither
• Pricey if you are one person or a small team, because Annual Pro starts at $6,000 a year
• Not for you if you don't use Slack, since that is where it works
• Watch out: the proof of concept is a 2-month commitment, and HIPAA and AWS deployment need Enterprise+

Pick Tettra if

• Fits if your team works in Slack and keeps fielding the same questions
• Works for teams whose knowledge already sits in Google Docs and could become a wiki

Look elsewhere if

• Skip it if you're a team of three or four, as the plan has a 10-user minimum, so $80 a month at least
• Not for you if you want a free plan, because there's only the 30-day trial and then a card
• Not for you if you need the app itself in another language, as the interface is English-only
• Pricey if you need SAML SSO or SCIM, which are paid add-ons on Scaling and included only in Enterprise
• Skip it if you want a desktop or phone app, since it runs in a browser and through Slack only

Question Base

Tettra

• Single sign-on (SAML) and SCIM provisioning are paid add-ons on Scaling and are included only in Enterprise.
• The app interface is English-only, although content can be written in any language.
• Tettra's site lists no desktop or mobile apps; it is used in a browser and through its Slack integration.

Internal knowledge base

Pages are written in Tettra's editor or built from existing Google Docs, Markdown files and other content, then grouped into categories with unlimited version history.

AI answers from Kai

When someone asks a question in Tettra or Slack, the Kai bot searches the knowledge base and replies. If it finds nothing, it helps assign the question to the right person.

Questions and answers

Questions and their answers are stored alongside pages, so a question that has been answered once can be found again instead of asked again.

Verification and content reports

Subject-matter experts verify pages on a set schedule, teammates can request new pages or updates, and reports list stale, unowned and public content.

Slack integration

From Slack, teammates can search Tettra, get AI answers in channels and direct messages, summarize threads and turn existing answers into knowledge base content.

Sharing and permissions

Single pages can be shared by link and whole categories published as external sites. Read-only users, guest users, invite-only categories and page locking control access.
