Enjoyed using it to start with but soon returned to Chrome. Now I have a personal browser/terminal hybrid I use. Lots of the ideas from arc were good. Sidebar tabs, splits, page editability.
Obviously more interesting if I'd thought to screenshot prior to going to bed but you can have multiple tabs in a 'stream' and they can be terminal or web tabs. The relay (which I'm pentesting in the screenshot) transports the AI chats to a paired phone where they're adapted to have a common UI across the Claude / Codex / Oh My Pi that I use. You can obviously see the Arc lineage to the ideas here.
