Notion

Notion is an all-in-one workspace from the US company of the same name that brings notes, a team wiki, databases, and project management together in one place. Over a hundred million people use it — from individuals building their own "second brain" to startups and large enterprises. It's the ideal tool for anyone whose information is scattered across dozens of files, chats, and spreadsheets and who finally wants order.

It works like a set of building blocks: you assemble each page from text, lists, images, tables, or databases exactly the way you want. You add information by hand or by importing it from other apps, link pages to each other, and your databases then show tasks by status, deadline, or owner — as a calendar, a board, or a list.
