Hey, developer here.
Thank you for the feedback.

Here is the reason why this might add some value for the users: Personally, I take screenshots of web designs from time to time. So, when I design, I should be able to ask questions like, "What was the website that had a fancy gradient button?" This will return screenshots + website address(OCR) for reference.
I am not sure how useful this will be for everyone, though. I am still talking to users.
