Slab AI

Slab is a company wiki from Slab Inc., and it sells itself as a knowledge base, pure and simple, not a replacement for the rest of your stack. Content lives in posts organised into Topics rather than a folder tree, so a topic carries structure and context, and Unified Search pulls answers from Slab pages plus connected tools — the site names Google, Slack, GitHub, Asana and Okta. The AI sits on that retrieval: AI Autofix tidies posts, while AI Ask and AI Predict are the question-answering layer that makes a fair comparison with Confluence AI or Notion AI. What it is genuinely good at is a small-to-mid company handbook that stays findable.

Slab is not a document vault, a tracker or an intranet portal, and its answers are as current as the posts someone maintained last quarter. Pricing sharpens the judgement: free forever for up to 10 users, which makes a small-team trial cost nothing, but the paid self-serve tiers I read were $6.67 and $12.50 per user per month billed annually, and the assistant features, GraphQL API, webhooks, SSO and SCIM only appear from Business upward — the entry tier gets AI Autofix but not AI Ask. A 15-person team wanting an AI wiki lands on the second-highest plan. Two checks before buying: bulk export, since the pricing page advertises import help and not a way out; and permissions, because Slab states plainly that it has no inherently read-only user account. Non-profits and schools get Startup free, and there is a 30-day money-back guarantee.
