Best Knowledge Base Tools
Notion
Best all-in-one workspace for teams willing to build their own tools.
Watch for: Steep learning curve for advanced features.
Pricing: A generous free plan is great for individuals. Paid plans start at $10 per user/month, but teams needing AI agents must choose the $20 per user/month Business plan.
More about Notion
Notion is a powerful all-in-one workspace for notes, projects, and company wikis. It's best for teams that want to customize their tools without writing code. However, its true power and new AI features are locked behind the expensive Business plan.
Check before choosing
- Meaningful AI features require the $20/user/month Business plan.
- Can feel slow with very large workspaces.
Slite
Best AI knowledge base for teams tired of stale documentation.
Watch for: There is no free tier available.
Pricing: Slite has no free plan and starts at $10 per user/month. To get the main self-maintaining AI features, you need the Pro plan at $20 per user/month.
More about Slite
