This is quite cool! Very excited for this concept. Kudos to launching on HN!

some genuine feedback on a frustrating early experience:

- I ran the suggested "Group all my tabs by topic" in productivity agent mode. It worked great.

- I then asked it to remove all tab groups and reset things, but was told this:

    This is a browser automation task. Please use **Agent Mode** for web interactions like clicking, filling forms, navigating sites, or extracting web content.

- Tried "agent mode" and was told:

    This is a productivity task. Please use **Chat Mode** for tab management, bookmarks, sessions, history, and content analysis.

- Basically was being sent back and forth. Went back to productivity mode and argued with it for a bit. The closest I could come to it removing all tabs groups was creating a new tab group encompassing all tabs, but couldn't get it to remove groups entirely. I'm guessing it might lack that API?

Overall, it'd be nice if every browser level action it took had an undo button. Or at least if it was smart enough/able to remove the tab groups it just created.

Will keep playing with it more.

edit1: one more weird issue: While running the chat interface on chrome internal pages like chrome://extensions, it would randomly browse me to google.com for some reason.

edit2: confirmed that productivity mode lacks a tool to ungroup tabs, just a tool to create tab groups.
