It has been a long time since I was last interested in a collaborative “document” creator. I have been exclusively been using Google Docs for years now. Notion is making me think twice about this decision. It is a breath of fresh air, and so long as it continues to develop, I think it could be a really interesting way to collaborate in the future:

Documents reimagined

Beautiful. Lightweight. Always organized. Notion is an expressive and collaborative document editor that gives your ideas a place to grow.
