> I will lose the credibility

There's grammatical mistakes and then there is sloppiness. Only the second makes me disregard someone's comment.

> I will lose the credibility of my message if there is too much mistake...

The correct way to write this is "if there are too many mistakes", because mistakes are countable and plural. And it's fine to make grammatical mistakes if English is not your native language. You can only get better by practising :-)

If I was French I'd end all my badly-written comments with a little French lesson, and that would make the readers forgive my errors and make me look intelligent and cultured. A beau mentir qui vient de loin, as we say in French. Le lémurien têtu porte des cache-oreilles.

It's perfectly fine to run your English text through an LLM if you're not sure about grammar/spelling. That's also how you learn to improve.

Your post is comprehensible but has multiple mistakes and they are a distraction (which is fine in this context, but in other contexts it might hinder communication).

I'm curious, why would you use an LLM to translate French to English? Why not use a dedicated translator such as DeepL, which will not only save you tokens/energy, but will also be much closer to your personal phrasing?

Same situation here. English is not my first language and I use Claude constantly to clean up my writing. Not to sound like someone else, just to make sure what I'm trying to say actually comes across clearly. The irony is that the more polished text sometimes gets less engagement because people assume it's fully AI generated, while a messier version with obvious non-native patterns would feel more human.

I would genuinely rather read this than read an AI-generated piece. AI-generated articles read like they are trying to sell me on their scam crypto meme coin.
