Slab: What It Actually Does, What It Costs, and Who It Fits
Slab is a lightweight, wiki-style internal knowledge base with unified search and AI features like AI Ask layered on top, built for smaller teams that want a simpler, more affordable company wiki rather than a heavyweight enterprise search platform.
Slab is the right pick for a small or mid-size team that wants a simple company wiki with unified search across its connected apps and a bit of AI layered on top, AI Ask for natural-language questions over your own docs, AI Autofix for cleanup, and AI Predict for surfacing relevant posts, without paying enterprise prices for a heavyweight platform built for large, permissions-complex organizations. Published pricing starts with a genuinely free tier for up to 10 users, with paid Startup and Business tiers reported at roughly $6.67 and $12.50 per user per month on annual billing, current as of 2026. It's not the right fit for a large organization that needs deep, permissions-aware search across dozens of enterprise systems, or a team that wants AI search to be the main event rather than a feature added to a wiki.
What Slab Is For
Slab is a company wiki built around a straightforward idea: give a team a clean place to write and organize documentation, then layer unified search and a bit of AI on top so people can find things without hunting through folders. Unified Search pulls results from Slab's own posts as well as connected integrations, with team-level search covering apps like Google Drive, Slack, GitHub, and Zendesk and individual-level search covering tools like Confluence, Jira, Asana, and Trello depending on what each user connects. On top of that search layer, Slab adds AI Ask for answering natural-language questions from your own documentation, AI Autofix for grammar and formatting cleanup inside the editor, and AI Predict for surfacing posts likely to be relevant to what someone's working on.
Where Slab differs most from a platform like Glean or Guru is scope and audience. It is not trying to be a permissions-aware search layer across dozens of enterprise systems, and it is not built around a formal expert-verification workflow. It's a lighter-weight wiki that happens to include AI search and assistance as features rather than as the entire product, which makes it a more natural fit for a smaller, less complex organization that wants one affordable tool for documentation and search, and a weaker fit for a large enterprise that needs the connector breadth or governance depth the category's bigger platforms are built around.
Key Features
- Wiki-style editor for writing and organizing company documentation, with templates and unlimited posts even on the free tier
- Unified Search across Slab's own content and connected integrations, split into team-level search (Google Drive, Slack, GitHub, Zendesk, and others) and individual-level search (Confluence, Jira, Asana, Trello, and others)
- AI Ask: natural-language question answering drawn from a team's own Slab documentation
- AI Autofix and AI Predict: in-editor grammar and formatting cleanup, plus proactive surfacing of posts likely to be relevant to current work
- Genuinely free tier for up to 10 users with unlimited posts and templates, rather than a time-limited trial only
- Published, self-serve tiered pricing with SSO, SAML, and SCIM available on paid tiers rather than a mandatory custom-quote sales process to get started
Pros & Cons
Pros
- ✔ Meaningfully more affordable than enterprise knowledge platforms, with actual published per-seat pricing and a genuinely free entry tier instead of a sales-led quote process
- ✔ Simple, approachable wiki interface that smaller teams can set up and adopt quickly without heavy IT involvement or a formal rollout
- ✔ Unified Search plus AI Ask gives a smaller team a reasonable amount of the "ask a question, get an answer" experience without needing a dedicated enterprise search product
Cons
- ✕ AI features (AI Ask, AI Autofix, AI Predict) are reported to be gated to paid tiers, so the free plan is mainly a documentation and search tool rather than a full AI assistant
- ✕ Connector breadth and search depth are considerably narrower than a platform built specifically for broad enterprise search, so it is a weaker fit as an organization grows past a smaller team
- ✕ No permissions-aware search model or expert-verification workflow the way the category's larger platforms offer, which matters more as document volume and sensitivity grow
- ✕ Some third-party reviewers describe Slab's AI capabilities as lighter than AI-first competitors, since AI was added on top of an existing wiki product rather than built as the core product
Pricing
Slab has a genuinely usable free tier.
| Tier | Price | What you get |
|---|---|---|
| Free | $0, up to 10 users | Unlimited posts and templates, and Unified Search, without AI Ask, AI Autofix, or AI Predict |
| Startup | Roughly $6.67/user/month billed annually | Everything in Free plus SSO, private topics, and Google Workspace, Slack, and GitHub integrations |
| Business | Roughly $12.50/user/month billed annually | Everything in Startup plus SAML, SCIM, a custom domain, Okta and OneLogin integrations, and the full AI suite (AI Ask, AI Autofix, AI Predict) |
| Enterprise | Custom quote | Advanced security, compliance, and support options for larger deployments |
Third-party sources report slightly different figures for Startup and Business (some cite $8 and $15/user/month instead), so treat exact numbers as approximate. Slab is reported to negotiate on price for larger commitments.
Pricing checked as of late 2026 and hedged as approximate - Slab changes plan names and limits periodically and third-party sources report slightly different figures, so confirm current figures directly on slab.com before budgeting.
Common questions
Yes, and it's a genuinely permanent free tier rather than just a trial. Slab's free plan covers up to 10 users with unlimited posts, templates, and Unified Search, though its AI features (AI Ask, AI Autofix, AI Predict) are reported to be reserved for paid tiers.
Slab publishes its own pricing. The free tier covers up to 10 users. Paid tiers are reported at roughly $6.67 per user per month for Startup and $12.50 per user per month for Business on annual billing, with a custom-quoted Enterprise tier above that. A few third-party sources cite slightly different figures (around $8 and $15/user/month), so confirm current numbers on slab.com.
Yes, layered on top of its wiki and Unified Search. AI Ask answers natural-language questions using a team's own Slab documentation, AI Autofix cleans up grammar and formatting in the editor, and AI Predict surfaces posts likely to be relevant to current work. These AI features are reported to be available starting on the Business tier rather than on the free plan.
Slab is a lighter-weight, wiki-style knowledge base aimed at small and mid-size teams, with AI search and assistance added as features on top of documentation and Unified Search. Glean is a heavier, permissions-aware enterprise search platform built for larger organizations connecting dozens of systems. Guru centers on expert-verified knowledge cards and a governance workflow aimed at teams that prioritize trust in the answer. Slab trades some of that depth for simplicity and a much lower price.
A large enterprise that needs permissions-aware search across dozens of connected systems will likely find Slab's connector breadth and governance depth too limited, and would be better served by a platform like Glean. A team that wants a formal expert-verification workflow for its knowledge base, rather than a general-purpose wiki, is likely better served by a platform like Guru.
