I like it because:

- I can handle many many tabs in a clean, efficient and organized way

- web pages show by default full screen, without: window bar, tool bar, url box, status bar, ...

- integration with AI tools

- it can handle several identities (work, home, hobby, ...) meaning that you be logged simultaneously on an app (gmail, notion, WhatsApp, ...) with different identities

- ...

What is missing: I cannot sync with Android

I guess I'm not the target customer because I don't keep tons of tabs open and I prefer to use separate browsers for my separate accounts. I haven't looked into the AI tools though.
