Surf is an intelligent notebook that brings your files and the web directly into your stream of thought.

Ask anything or navigate...

The new Surf browser shows why everyone's trying to connect AI to the web

As a way to actually make sense of ... research you do around [your browser tabs], there’s nothing else like it.

Its main selling point is AI (I know, I know, bear with me), but in a way that actually makes sense.
