Notion

Notion is the best tool in this list at the thing none of the others do: keeping your projects and your knowledge in one place. A project in Notion sits next to the meeting notes that spawned it, the spec it implements and the wiki page it updates — connected by relations, not links to another app. For teams whose real problem is scattered context rather than complex scheduling, that is decisive.

As a pure project manager it is deliberately lightweight. Databases with board, timeline and calendar views cover standard tracking, and the 2025-era Projects templates plus Notion AI (bundled into Business at $15/user/month) close some gaps — AI summaries of sprawling pages are genuinely excellent. But there is no native time tracking, no workload management and no true portfolio roll-up; dependencies are manual. Ambitious PM setups in Notion become beautiful systems that one enthusiast maintains and everyone else tolerates.

Our guidance: choose Notion when documentation is the center of gravity and project needs are moderate — startups, content teams, small product orgs. The free tier is excellent for individuals, Plus at $10 suits small teams. Pair it with Linear (their integration is first-class) when engineering outgrows it, rather than forcing Notion to be something it is not.
