A knowledge base is the most cost-effective way to scale customer support. Instead of answering the same questions thousands of times, you write the answer once and let users find it themselves.
We evaluated the top knowledge base tools based on features, pricing, search quality, and integration with broader support workflows.

- Powerful search — Users find answers instantly

The 7 Best Knowledge Base Tools
1. feedto.me — Best for Product Teams
Pricing: Free plan; Starter at €19/month
feedto.me's KB is designed for product teams that want a help center connected to their feedback boards and support inbox. When users can't find an answer, they can submit feedback or start a support conversation — all within the same platform.
- ✅ Rich text editor
- ✅ Category organization
- ✅ Built-in search
- ✅ "Was this helpful?" feedback
- ✅ Connected to feedback + inbox
- ✅ Free plan with 10 articles
2. Notion
Pricing: Free plan; Plus at $10/user/month

Best for: Teams already in Notion that need a quick public KB
3. GitBook

4. Intercom Articles
Pricing: Included in Intercom plans (starting at $74/month)
Intercom's Articles feature is well-integrated with their chat widget and support inbox. Articles are suggested to users before they chat, reducing ticket volume.
