Slab and Notion can both serve as a team wiki or internal knowledge base, but their scope is quite different.
Slab is built mainly around company knowledge. Notion combines documentation with databases, project workflows, websites, and a much broader AI product.
Slab vs Notion at a glance
| Slab | Notion | |
|---|---|---|
| Best for | Internal knowledge bases and team wikis | Docs combined with broader work management |
| Free plan | Up to 10 users | Unlimited pages for individuals; block limit with 2+ members |
| Lowest paid plan | $6.67/user/month | $10/member/month |
| Knowledge verification | Included | Included in wikis; broader verification on Business+ |
| Cross-tool search | Unified Search | Enterprise Search on Business and Enterprise |
| AI | Writing and knowledge features depending on plan | Broader AI suite on Business and Enterprise |
| Databases | No general-purpose database system | Built in |
| Project management | Mostly through integrations | Built in |
| Public publishing | Public posts and topics; custom domains on Business+ | Notion Sites; custom domains available as a paid add-on |
| Version history | 90 days on Free, 365 on Startup, unlimited on Business+ | 7 days on Free, 30 on Plus, 90 on Business, unlimited on Enterprise |
The biggest difference is scope. Slab puts most of its product around documentation and knowledge sharing. Notion can become a much broader system for how a team works.
Slab vs Notion: Key differences
Knowledge management
Slab organizes content as Posts and Topics, while Notion uses pages and database-backed wikis.
A few differences affect how the two feel in everyday use:
- Structure: Slab Topics can contain subtopics, and the same Post can appear in more than one Topic. Notion gives teams more freedom to shape the hierarchy themselves.
- Verification: Slab includes verification on every plan. Notion supports verification inside wikis, with broader page verification available on Business and Enterprise.
- Ownership: Notion wiki pages can have owners who are notified when verification expires. Slab can assign a verifier responsible for reviewing a Post.
- Reading: Slab keeps published Posts separate from the editing interface, giving the knowledge base a more conventional reading mode.
Slab gives teams more of the knowledge-base structure upfront. Notion leaves more room to adapt the wiki around other workflows.
Search and integrations
Slab's Unified Search can search Slab alongside connected services such as Google Drive, GitHub, Slack, Zendesk, Dropbox, and Linear. Teams can keep documentation in Slab while continuing to use dedicated tools elsewhere.
Notion's Enterprise Search is available on Business and Enterprise. It searches Notion and connected apps and can return AI-generated answers based on the information it finds.
Slab treats cross-tool search as a knowledge-base feature. Notion ties it much more closely to its AI product.
AI
The AI comparison has changed considerably in the past few years.
| Slab | Notion |
|---|---|
| AI Autofix on Startup+ | Limited AI trial on Free and Plus |
| AI Predict and AI Ask on Business+ | Notion Agent on Business+ |
| Advanced AI Ask on Enterprise | AI Meeting Notes and Enterprise Search on Business+ |
| No separate credit system listed for these features | Custom Agents use separate Notion credits |
Slab keeps AI close to writing and knowledge retrieval. Notion uses AI across more of the product, including meeting notes, connected search, and automated work through Custom Agents.
Databases and project management
Notion is considerably more capable here. Its databases support custom properties, formulas, filters, dependencies, and different layouts. Teams can use them for project tracking, CRM-style workflows, content planning, or task management.
Slab has no equivalent general-purpose database system. It integrates with tools such as Jira, Asana, Linear, and GitHub, allowing project information to stay in those products while related documentation lives in Slab.
For teams already happy with their project-management stack, that separation can work well. If consolidating documentation and structured project work is part of the goal, Notion has much more to offer.
Permissions and admin controls
The plan requirements differ more than the basic feature lists suggest.
| Feature | Slab | Notion |
|---|---|---|
| SAML SSO | Business+ | Business+ |
| SCIM provisioning | Business+ | Enterprise |
| Audit logs | Enterprise | Enterprise |
| API | GraphQL API on Business+ | Public Notion API |
Slab also controls viewing and editing at the Post and Topic level. Notion layers permissions across pages, teamspaces, and databases, with more detailed database permissions available on Business.
Public publishing
Both tools can publish documentation outside the company, but the experience is different.
Slab can make individual Posts or whole Topics public, and external readers do not need an account. Business and Enterprise also support custom domains.
Notion has gone further with Notion Sites. Pages can be published as websites on every plan, with paid plans adding more customization. A custom domain requires a separate paid add-on.
If public content is only an extension of an internal wiki, Slab covers the basics. Notion gives teams more options when the public site itself is an important part of the use case.
Slab vs Notion pricing
Slab is cheaper at both of its publicly priced paid tiers.
| Plan level | Slab | Notion |
|---|---|---|
| Free | $0, up to 10 users | $0 |
| First paid plan | Startup: $6.67/user/month | Plus: $10/member/month |
| Business | $12.50/user/month | $20/member/month |
| Enterprise | Custom pricing | Custom pricing |
Prices above use annual billing, and the similarly named plans are not direct feature equivalents.
Slab Free supports up to 10 users, unlimited Posts and Topics, verification, Unified Search, and 90 days of version history. Startup removes the user limit and extends version history to 365 days.
Notion Free is more generous for a solo workspace, where pages and blocks are unlimited. Shared Free workspaces eventually hit a block limit. AI can also raise the cost of Notion: Plus only includes limited trial access, while the core AI suite requires Business at $20/member/month.

Slab or Notion: Which should you choose?
Choose Slab if
- You mainly need an internal knowledge base or company wiki.
- You want a more structured documentation workflow with built-in verification.
- Your team already uses dedicated tools for projects and development.
- You want lower per-user pricing for a shared team wiki.
Slab is the more focused choice. It does less than Notion overall, but the product is built much more directly around creating, maintaining, and finding company knowledge.
Choose Notion if
- You want documentation and databases in the same workspace.
- You plan to manage projects or other structured workflows alongside your wiki.
- You want a much broader set of built-in AI features.
- You prefer a highly configurable workspace and do not mind spending more time setting it up.
Notion is the more flexible option. It can replace more tools, but that broader scope also makes it more complex than Slab.
