Notion is a note taking app. With a shared note feature. (You are right.)

And then it has a ton of more features, almost too many too mention.

Anything apart from simple unformatted text is (in summary) called a component.

It has a wide variety of components. Some of these components have a level of intelligence to them. Some of these components are references and links to information in other notes. Some of them are intelligent components that selectively show information in other notes. Some of them are intelligent components that selectively show information in other components.

Components can be tables, formatted headers, lists, dynamic content, charts, “views” similar to sql views, etc.

That is all I know.
