I have been looking for something like this for some time and what would you know - I just have been contacted to test it! And boy oh boy I like it so freaking much!
This is what the developer wrote on Reddit about it:
Hey, Civitians! I have a problem with some cool images not showing a prompt!
To bypass it I had to save the image to my PC, right-click it, and open it in Notepad. If I am lucky, it is encoded in proper text format. If I am lucky again it is a PNG, and not a JPG, meaning that it has the generator metadata, then I would see the prompt. After I would have to copy it, clean spaces, sanitize it, and finally use it. I hated it, it took so much of my time!
So I have developed a Chrome extension that allows users to copy any prompt in any image in civitai space that has a prompt.
Super easy to use! Just right-click an image and select "Copy Prompt if Any" - and that's it, it's copied in your clipboard!
Doesnt matter if it is hidden or not. As long as the image has not been converted to another format or has been enhanced with external graphic tools, you will be able to get the prompt!
Would you be interested to test it? If so, just grab it from this link!

In the next update, I plan to add an automatic sanitation tool to filter it to positive and negative and show other generation data as well.
P.S.: This is a public beta, so some exceptions apply - I am working on solving them! It would help out a lot if you test this extension and share your findings with me!
Here is the Developer on Civitai - just write him a message if you want this tool to get better: https://civitai.com/user/digitalego
And I am getting on the hunt for these juicy images I have been longing for so much time to generate, mwahahah!
