Looks to my like an effort to pivot from an AI embedded Browser after the ChatGPT Atlas release into a local system Browser.

I still don't see the advantage I get for my local system? Nearly all of the actions on the demo page are doable with chatGpt in one or three interactions.

The big difference UX wise between chatbots and Surf is that Surf is built entirely on editable documents that you can mold / craft into an output (vs chat).

We actually had a chatbot, but our explorations showed that notes were a more effective in many cases!

An example of local data is that "Applets" made in Surf can be opened / updated from your local code editor, they're just HTML files.

Umm -- not being tied to ChatGPT? Like, that's huge. I personally do not consider consistently using any AI tool unless it has a local option. I've been air-quotes "paranoid" about things like this my whole life and it's served me QUITE well.
