Notion

Notion is an all-in-one workspace for notes, documents, wikis, and project management that helps teams and individuals plan, write, and stay organized. Create pages with rich content, build databases for tasks and projects, and collaborate in real time with comments, mentions, and sharing. Use templates to set up workflows quickly and connect your knowledge with linked pages so information is easy to find. It replaces scattered tools with a single, flexible system for managing ideas and getting work done.
