Best Knowledge Base Software in 2026: Pricing & Comparison
We compared four knowledge base platforms on published pricing, free or trial options, public vs private content and AI features so support and internal teams can shortlist faster.
- Atlassian teams: Confluence β Free up to 10 users; Standard from about $6.70β$7.15/user/month.
- Flexible docs and wiki: Notion β Free plan; paid from roughly $10/user/month.
- Dedicated customer help center: Helpjuice β flat $249/month for up to 30 users.
- AI knowledge agents: Guru β currently quote-based enterprise packaging.
Knowledge base software lets teams create, organize and search internal or customer-facing documentation so answers are findable without repeated tickets or Slack messages.
We evaluated every vendor on the same fields: published pricing, free plan or trial, core focus and main limitation. The order is not a quality ranking. Sort rule: public $0 / published price first, quote-led last.

Does Helpjuice charge per reader?
No. Helpjuice plans include unlimited readers. The published caps are on credentialed users (authors, editors, viewers who log in).
Will Confluence prices rise in October 2026?
Yes. Atlassian has announced Cloud list-price increases effective 13 October 2026 PT for Confluence Standard and Premium. Confirm the exact band on the pricing page.
Is Guru still available self-serve?
Current public packaging is quote-based. Prior self-serve pricing is no longer listed on the marketing site.
