Nice idea.

Is 'plucking' something and pasting the prompt into Claude the same as taking a screenshot and uploading it to Claude?

I tend to upload screenshots a lot. If 'plucking' essentially does the same thing, without cluttering my desktop with screenshots, I'd be interested in trying it out.

It's not, it actually currently doesn't even take screenshots. It actually looks at the html and includes actual structure and values from the webpage.

Thanks for asking, maybe I should make it clearer on the website I would also add a screenshot functionality later, if people feel like current approach is not enough.

Depending on your OS/screenshot tool, you can bind a key to select an area and copy it to the clipboard, then paste directly into Claude (Ctrl/Command+V). No cluttering.
