Ai is ai regardless of the brand name. Whether it is CHAT GPt or Quillbot, they are both simply different means to the same end. I just looked up Quillbot and it is an AI paraphrasing tool. Meaning you feed in one input, and out comes another.

Actually, there is no difference between Quillbot and Chat GPT.

Quillbot is an advanced AI writing tool that utilizes cutting-edge GPT-3 technology to enhance your writing and editing experience

If Quillbot isn't rewriting your work, then what is the problem with using something like Grammarly since it does not get you flagged?
