It’s overkill for this audience. HN is pretty forgiving of spelling and grammar mistakes, so long as the main information is clear. I’d encourage anyone that wants to share a comment here to not use an LLM to help, but just try your best to write it out yourself.
Really - your comment on its own is good enough without the LLM. (And if you find an error, you can always edit!)
If we really wanted ChatGPT’s input on a topic (or a rewording of your comment), we can always ask ChatGPT ourselves.
