Notion review

An incredibly flexible all-in-one tool with a best-in-class editor for building custom internal wikis.

Verdict

Notion makes the list for its unparalleled flexibility and beautiful editor, making it the best option for teams who want to build a custom internal knowledge base that lives alongside their projects, notes, and databases.

What customers praise

The block-based editor and database functionality allow for the creation of dynamic, interconnected documents that are impossible in most other tools.

What customers criticise

It lacks the core features of a dedicated knowledge base, such as advanced analytics, version history for public pages, and ticket-deflection workflows.

Best for

Startups and SMBs that want a single, highly flexible workspace for their internal wiki, project management, and docs.
