Sometimes, asking Generative AI to help proofread your paper can be a useful tool. AI can catch spelling and grammar mistakes well, although it sometimes struggles to recognize discipline-specific terminology.
One danger with Generative AI proofreading is losing your personal "voice" in your writing. Sometimes, AI will overdo the editing suggestions, so by the time you're done it won't event sound like you wrote it. Don't automatically accept every change an AI tool recommends, take the time to think about if the suggested changes make sense.
Using spellcheck in Microsoft Word or similar tools is not Generative AI, although some editing tools have started adding Generative AI options to their products.
