Notion
Slab
Notion and Slab both target teams building internal knowledge bases, but their pricing philosophies are radically different. Notion bundles AI exclusively in its $20/user Business tier after a major May 2025 restructuring, while Slab offers the cheapest paid tier in the category at $6.67/user with no AI features at all. This comparison breaks down what you actually get at each price point — and whether either tool is truly worth the spend.

Strengths & Weaknesses
Deep Dive Analysis
An in-depth look at the three most critical pricing dimensions for teams evaluating Notion and Slab — value for money, scalability costs, and hidden costs and limitations.
Slab wins on raw affordability — $6.67/user/month is genuinely the cheapest paid wiki in the category. For teams that only need a clean internal wiki with good search and real-time editing, Slab delivers on its promise without overpaying. Notion's value proposition is more complex. At $10/user/month (Plus), you get unlimited blocks and databases but essentially no AI — just a 20-response one-time trial. Real value only emerges at $20/user/month (Business) where full GPT-4 and Claude 3.7 AI, AI Agents, and Enterprise Search are bundled. If your team actually uses AI writing assistance, Notion Business at $20/user can justify itself. If not, you are paying double for features you won't use.
Per-user pricing models punish growth, and both Notion and Slab operate on this model. A 50-person team on Notion Business pays $1,000/month (annual) just to access AI — before any enterprise add-ons. Slab scales more gently at $333/month for the same 50-person team on Startup, but Slab's Business tier immediately goes to custom pricing, meaning larger teams face sales negotiations with no pricing transparency. Notion at least publishes Business tier rates. Neither tool offers workspace-based pricing that keeps costs predictable as headcount grows. Teams adding contractors, clients, or seasonal staff will see costs inflate linearly with every seat added.
Notion's biggest hidden cost is the AI cliff. Teams adopting Notion expecting AI capabilities will quickly discover that Plus tier AI is a 20-response dead end — not a functional AI tool. Upgrading from Plus to Business doubles the per-user cost. For a 30-person team, that is an unplanned $300/month increase. Notion also locks version history to 7 days on Plus — inadequate for any serious documentation governance. Slab's hidden limitation is what it cannot do regardless of price. No API, no custom domains, no SSO below Business, and no AI means teams will eventually need a second tool to fill capability gaps — adding a separate cost that makes Slab's low per-user price misleading when total stack cost is calculated.

Pricing Verdict
Slab is the clear winner on price — $6.67/user/month is the most affordable paid wiki available, and the free tier for up to 10 users is genuinely the best in class for small teams. Notion costs 2–3x more at equivalent tiers, and full AI access requires the $20/user Business tier — a significant commitment for teams expecting AI to be a standard feature. However, Slab's low price reflects its limited scope. Teams that need AI writing assistance, API integrations, external delivery, or compliance features will eventually outgrow Slab and face costs of adding separate tools. Notion offers more capability ceiling but charges premium pricing for it. Neither tool offers workspace-based pricing that keeps costs truly predictable at scale.
Our Recommendation
Notion and Slab occupy opposite ends of the internal wiki spectrum. Notion is a feature-rich all-in-one workspace where AI capability requires a $20/user Business commitment, making it expensive for teams that need AI but over-featured for those that don't. Slab is the most affordable and simplest wiki available, but it offers no AI at any price point and lacks the API access, custom domains, and compliance features that growing teams eventually require.

Winner: Docsie
Both Notion and Slab are internal-only tools with no external documentation delivery, no multi-tenant portals, and no video-to-docs conversion at any price tier. Docsie fills every gap both tools share — workspace-based pricing with AI credits instead of per-seat inflation, custom domains and branded multi-tenant portals for external client delivery, 100+ language auto-translation, and the ability to convert any video or PDF into structured searchable documentation — all starting at $199/month for teams of up to 15 users with 300,000 AI credits included.
Common Questions
Q: Does Notion include AI on the Plus plan?
A: No. Following Notion's May 2025 restructuring, full AI access is exclusively available on the Business tier at $20/user/month (annual). Plus plan users ($10/user/month) receive only a one-time 20-response AI trial — not an ongoing AI feature. If AI writing assistance is part of your workflow, you must budget for the Business tier. Legacy users who purchased the standalone AI add-on before May 2025 were grandfathered in.
Q: Is Slab really free for 10 users?
A: Yes, and it is one of the most genuinely useful free tiers in the internal wiki category. Slab's free plan supports up to 10 users with unlimited posts, real-time collaboration, and 90-day version history — features that Notion's free tier reserves for individual use only. The trade-off is that Slab's free plan has no AI features, no API access, and no SSO, and it hard-caps at 10 users with no pathway to scale without upgrading to the Startup paid tier.
Q: How much does Notion cost for a 25-person team that needs AI?
A: A 25-person team on Notion Business (the minimum tier for full AI access) costs $500/month billed annually, or $600/month on monthly billing. This is a significant commitment compared to the Plus tier at $250/month annually — but Plus effectively provides no AI for team workflows. Teams should budget for Business tier from the start if AI writing assistance is a requirement, rather than upgrading later and absorbing the doubled per-user cost.
Q: Does Slab offer enterprise pricing?
A: Yes, but with no published rates. Slab's Business tier — which includes SSO, advanced security, and dedicated support — requires contacting sales for a custom quote. This lack of pricing transparency makes it difficult to budget for Slab at enterprise scale. The only public pricing is the Startup tier at $6.67/user/month (annual). Teams evaluating Slab for organizations above 50 users should expect a sales process before seeing any numbers.
Q: Is there a better alternative to both Notion and Slab for documentation?
A: Yes — Docsie is purpose-built for teams that have outgrown internal-only wikis. Unlike Notion and Slab, Docsie offers workspace-based pricing starting at $199/month (not per-user), full AI features included without tier restrictions, multi-tenant portals for external client delivery with custom domains, 100+ language auto-translation, and the ability to convert existing training videos and PDFs into structured documentation. For teams needing to deliver documentation to clients or operate across multiple languages, Docsie addresses every gap that Notion and Slab share.
Q: Which tool has better version history — Notion or Slab?
A: Slab wins on version history at the free tier — 90 days versus Notion's 7 days on its Free and Plus plans. At paid tiers, Slab's Startup plan ($6.67/user) includes unlimited version history, while Notion requires the $20/user Business tier to reach 90 days and Enterprise for unlimited history. For teams where version control and auditability matter, Slab provides better value at lower price points specifically on this feature.
