Slab
Knowledge base and team wiki with search across connected tools
What is Slab?
Slab is a knowledge base and wiki for company documentation. Content is written as posts and organized into Topics, and a unified search returns results from Slab and from integrated tools in one place. Posts can carry a verification status with an expiry date, and the free plan covers teams of up to 10 users.
Slab has a free plan. Paid plans start at $6.67 per user / month, billed annually ($8 billed monthly). See every plan
Good for
- Teams of up to 10 that want a free internal wiki
- Companies that want one place to search docs and connected tools
- Non-profits and schools, which can get the Startup plan free
Worth knowing
- The Free plan stops at 10 users and has no private topics, no custom domain and no AI features.
- SAML-based SSO, SCIM, the API and webhooks need Business at $12.50 per user / month billed annually; audit logs are Enterprise only.
- Slab has no read-only accounts: billing counts every user who can log in, and guests are capped at 3 or 5 per user below Enterprise.
- The downloads page offers desktop apps for Mac and Windows and a Chrome extension, but lists no mobile apps.
Key features
- Posts and Topics
- Content is written as posts and grouped into Topics, which organize related posts and give readers context. Posts and topics are unlimited on every plan.
- Real-time editor and templates
- The editor applies consistent formatting by default and lets several people work on a post at once. Templates are included on every plan.
- Unified Search
- One search box returns results from Slab content and from the tools connected to it, so answers stored elsewhere surface in the same list.
- Post verification
- A published post can be given a verifier and a review interval. A banner shows who verified it and when that expires, and verifiers are reminded to recheck it.
- AI Autofix, Predict and Ask
- Slab lists three AI capabilities: AI Autofix from the Startup plan, and AI Predict and AI Ask from Business. The Free plan includes none of them.
- Integrations, API and webhooks
- Standard integrations such as Slack, GitHub and Google Workspace are capped at 10 on Free. The GraphQL API, webhooks and premium integrations start on Business.
