In-depth: why these tools made the cut

Confluence logo

Confluence is built for large engineering organizations: strict permissions, integration with Jira, page templates, governance features. For 1000+ person companies that need structured documentation with controls, Confluence is the rational default.

The UX feels heavier than Notion's modern blocks model. Younger companies often resist Confluence specifically because of this. Use Confluence when scale and governance matter more than UX delight.

How to choose knowledge base software

  1. Identify audience

    Internal team docs: Notion, Confluence, Slab, Slite. Customer-facing help center: Zendesk Guide, Intercom Articles, Helpjuice, Document360. Developer docs: GitBook, Mintlify, ReadMe, Docusaurus. Don't try to use one tool for all three.

  2. Plan for SEO and discoverability

    Customer-facing knowledge bases need to rank on Google for support queries, your customers Google before contacting support. Verify the platform handles SEO basics (custom URLs, meta tags, structured data) before committing.

  3. Audit AI/search depth

    Modern KBs need good search; AI-powered Q&A is increasingly expected. Intercom's Fin AI, Notion AI Q&A, and dedicated KB AI search tools differ in quality. Test search on your real content before assuming.

Honorable mentions

Tools that didn't crack the headline list but deserve a look depending on what you optimize for.

  • Slab logo
    Slab Best for mid-market internal wikis

    Slab targets mid-market companies that find Notion too loose and Confluence too rigid. Solid pick for 50–500 person teams.
