What are some text editing sites geared toward Mandarin grammar?

I've usually just written in Google Docs but I dislike how it will always highlight pinyin as an error and won't always format or count characters correctly since it's geared toward English.

What are some text document editors that are geared toward Mandarin? Ones that allow you to save various documents and have character counters and could correct bad grammar with autocorrect. Preferably ones that don't have a lot of GenAI, since that's what I've mostly found so far, but just any options would be nice.
