Ha cool, literally vibe coded this today for the page I was working on! But much simpler of course, it would just pick up the DOM path + a description I write, no screenshots or drawing or anything. I am sure I could also use this on a page I am working on locally currently and hosting on localhost:8000 let's say, right? Because that is probably the main way I would use, I don't see much need to use it on a live page since that is not where I am iterating on it.
Also, how I put it up for myself was that all the annotations would get saved into annotations.md on my disk (browser would ask once for permissions to write to disk), and I would tell Claude Code to run file watcher on that file and automatically respond to anything I add. Then it would checkmark them when they are done, and I could also edit them either via the tool in the browser or directly in the file if I wish.

Btw doesn't work for me at the moment, I tried both in Chromium and Chrome, nothing happens when I press Activate or Open panel. I am on Linux though.

@martin_sosicย Thank you for the heads up. I did just submit a new version. But, I will definitely looking into the Linux compatibility as well.
