Direct answer
What is Slab?
Slab is a modern knowledge base and wiki platform designed to help teams create, organize, and discover documentation using structured Topics, clean editing, and unified search across external tools.
Slab provides a purpose-built knowledge base and internal wiki engineered to facilitate clear documentation across technical and non-technical teams. Instead of positioning itself as an all-in-one project management system, the platform concentrates entirely on knowledge sharing, integrating with surrounding task managers, spreadsheets, and file storage. Content creation is powered by an intuitive editor designed to produce clean, well-formatted documents by default with real-time collaboration. Organization is handled through Slab Topics, which provide structured context to company policies, meeting records, and guides rather than relying solely on traditional folder hierarchies. For information retrieval, Slab incorporates Unified Search, pulling relevant query results from internal Slab posts as well as integrated third-party platforms like Slack, GitHub, and Google Drive. Higher-tier plans incorporate AI capabilities including AI Autofix, AI Predict, and conversational AI Ask, alongside administrative features such as post verification cycles, custom domains, SAML SSO, and SCIM provisioning.
Slab focuses strictly on knowledge management rather than trying to replace an entire workplace stack, pairing standardized document formatting with Unified Search that indexes both internal posts and connected tools like GitHub, Slack, and Google.
