Slab

Slab is a team wiki and documentation tool. Teams use it to write, organize, and search internal knowledge such as onboarding guides, engineering docs, and meeting notes. An AI feature called AI Ask answers questions from your Slab content, and two more, AI Autofix and AI Predict, help with writing and formatting as you type. It is made by Slab Inc. and connects to Google, Slack, GitHub, Asana, and Okta. Every plan includes single sign-on; paid plans add unlimited version history, SAML-based single sign-on, and SCIM user provisioning, which automatically adds or removes employees as they join or leave.

This fits a company that has outgrown a shared drive full of scattered documents but does not need the size or cost of a large enterprise search platform, such as an engineering, product, or operations team that wants one clean, searchable home for how-to guides and decisions. A practical starting point is the Startup plan, around $6.67 per user per month billed annually, rolled out to one or two departments before deciding on Business or Enterprise; treat that number as an estimate. The Free plan caps at 10 users, so a broader rollout means moving to a paid tier fairly early. Watch for attachment size limits on lower tiers, and confirm the SCIM and SAML features you need are on your chosen plan, not just Enterprise.
