Best Knowledge Base Software

Knowledge base software is where the team keeps the answer after the meeting ends: a wiki, a spec, a process page. The best one is the page people will actually update. A perfect archive that nobody opens is just another folder.

Frequently asked questions

What is the best knowledge base software?

Notion is the best team wiki in this set. ClickUp is the better choice when the wiki should live in the same workspace as tasks, docs and reporting.

Can project management software replace a wiki?

Sometimes. ClickUp lists docs and wikis. Notion is still stronger when the knowledge base is the main product and project features are secondary.

Is there a free knowledge base tool?

Notion's free plan suits an individual. ClickUp's free plan allows unlimited members, with 60MB of storage and limits on Spaces, forms and whiteboards.
