Notion

Notion combines documents, a team wiki, project tracking and lightweight databases in a single tool. Every page is made of blocks that teams arrange to fit the way they work, so the same workspace can hold meeting notes, a product roadmap and a company handbook. Databases can be viewed as tables, boards, timelines or calendars, and Notion AI helps write, search and answer questions across the workspace. It is used mostly by startups and by product, engineering and operations teams that want to replace several separate tools with one.
