Slab is the best pick for small teams that want to start free — its free plan covers up to 10 users with verification and unified search, and AI features arrive on paid tiers from $8 per user per month. Slite is the best pick when you want AI doing real maintenance work — its Pro plan adds an agent that finds stale docs across 20+ connected tools and routes every fix through human approval, though Slite removed its free plan in June 2026 and starts at $10 per user per month. Both replace the shared drive where answers go to die with a wiki that keeps docs verified and searchable.
The two, in one line each
Slite is a team wiki with doc verification, AI answers, and an agent that flags stale docs for human approval, with paid plans from $10 per user.
Slab is a team knowledge base with verification and unified search, free for up to 10 users, with AI features on paid plans.
Where each one actually wins
Slite wins on AI depth. Following a June 2026 relaunch it sells a "self-maintaining knowledge base": Basic is $10 per user per month billed yearly and includes Ask, an AI search and answers feature limited to 30 questions per seat per month within Slite docs, plus doc verification workflows. Pro is $20 per user per month billed yearly and adds Ask across connected tools, a Slite Agent that detects stale docs across 20+ tools and proposes fixes with human approval, doc fact-checking, and a pooled credit allowance of 50 per seat. MCP and API access come on all plans. There's a 14-day trial with no card, and no free plan.
Slab wins on cost of entry. Its free plan supports up to 10 users with verification and unified search but no AI. Startup is $8 per user per month on monthly billing ($6.67 annual) and adds AI Autofix; Business is $15 monthly ($12.50 annual) and adds AI Predict and AI Ask plus premium integrations; Enterprise requires at least 100 users. It offers a 30-day money-back guarantee rather than a free trial. Its Microsoft Teams integration requires the Business plan, and whether AI Ask works inside Slack or Teams is worth confirming before you buy.
If you want the cheapest way to start, or you're under 10 people and don't need AI yet, Slab is the more direct fit. If you want an agent keeping your docs current across your tools, Slite is the better match.

FAQ
Does Slite still have a free plan? No. Slite replaced its free plan with a 14-day, no-card trial in June 2026. Paid plans are $10 (Basic) or $20 (Pro) per user per month, billed yearly.
What about Guru? Guru's pricing page now shows only a custom quote-based package, with no public per-seat price or trial, so it's aimed at mid-market and enterprise teams rather than small ones.
What about Tettra? Tettra is a Slack-first wiki with AI answers in Slack, listed at $8 per user per month with a 10-user minimum and a 30-day free trial; the page doesn't make clear whether that price is monthly or annual, so confirm before buying.
How many AI questions can I ask? On Slite Basic, Ask is limited to 30 questions per seat per month, and Pro raises usage through a pooled credit allowance plus cross-tool search.
Does an AI knowledge base replace documentation habits? No. Both rely on verification workflows so someone owns each doc. The AI helps people find answers and flags stale content, but accuracy still depends on keeping owners assigned.
