Only invited users who accept count as licenses, deactivated users do not, and Slack-only users are free. SAML SSO and SCIM are add-ons on Scaling with no published price. Enterprise is quote-only and includes SSO, SCIM, onboarding, custom reporting and discounts past 250 licenses.

Is Tettra worth the price?
Tettra is good value for Slack-centered teams of 10 or more that want a cheap internal wiki with AI answers, and the free Slack-only seats help. It gets awkward for teams under 10 users because of the minimum, and for buyers who need SSO, SCIM or group permissions, since those add cost beyond the $8 list price. It is not meant for customer-facing help centers.
Worth it if
- Small and mid-size teams living in Slack that want a cheap internal wiki.
- Teams of 10 or more who want a published monthly price.
Look elsewhere if
- Teams under 10 users (10-user minimum on Scaling)
- Buyers who need SSO and SCIM included in the base plan.
- Customer-facing help centers.

Pricing details most reviews leave out
- SAML SSO and SCIM are paid add-ons on Scaling, and group permissions need the SCIM add-on.
- 10-user minimum on Scaling.
- Seats are counted only after an invite is accepted; Slack-only users are free.
- Competitor comparison pages (Docsie) claim no SOC 2 report; not confirmed by the vendor from Tettra itself.
Our verdict on Tettra
Tettra is an internal wiki and AI Q&A tool built around Slack, and its pricing is simple on the surface: $8 per user per month on the Scaling plan, with a 10-user minimum. That means the lowest possible bill is $80 per month before any discount, and teams under 10 users pay for seats they do not have. The AI answers and the Slack bot are included on Scaling, which helps the value case.
The bigger cost issue is identity. SAML SSO and SCIM are paid add-ons on Scaling, with no published price, and group permissions need the SCIM add-on. G2 reviewers rate Tettra 4.7 from 159 reviews, but one recurring complaint is that SSO and SCIM cost extra on the entry plan. Budget for a quote if your security team requires either.
