Would anyone notice if you spell-checked or got narrow feedback about grammar? No. I'm not dang, but perhaps a very reasonable interpretation of the rules is: If the AI is generating the words, don't. If it tells you something about your words and you choose to revise them without just copying words the AI output, it's still your words.

(As an experiment, I took that paragraph and threw it into gemini to ask for spell and grammar checking. It yelled at me completely incorrectly about saying "I'm not dang". Of its 4 suggestions, only 1 was correct, and the other 3 would have either broken what I was trying to say or reduced the presence of my usual HN comment voice. So while I said the above, perhaps I'm wrong and even listening to the damn box about grammar is a bad idea.)

That said, I often post from my phone and have somewhat frequent little glitches either from voice recognition or large clumsy thumbs, and nobody has ever seemed to care except me when I notice them a few minutes after the edit button goes away.
