I love this extension! It does a good job of finding content that might have been plagiarized from somewhere else. It does a good job of finding AI-generated text, too. This extension is also easy to use and integrates with Google Docs. I would highly recommend it to anyone who writes often.

This really helped. However, I uploaded original work and it still highlight what could be marked as AI. That was a little confusing, but overall it was useful
