What about AI-assisted writing? e.g. improving style, grammar, readability, making explanations clearer and better structured? especially for non-native writers this is a challenge and not many can hire an editor or even a proofreader. I wonder if such use gets “penalized” by search engines the same way AI-generated content might?
