Notion

Notion's pitch is one app that replaces ten: notes, docs, databases, and project boards, all linked and searchable. That flexibility is the whole appeal, and it holds up right until a database grows large, at which point pages can start taking noticeably longer to load. Small, technically comfortable teams who like building their own systems get the most from it; if you just want a task list that works on day one, look elsewhere on this page.
