I have been using LanguageTool[1] for years as "an open source alternative to [old school] Grammarly". It doesn't do that fancy "make this text more professional" AI stuff like this or Grammarly can now do, but they offer a self-hosted version so you don't need to send everything you write to OpenAI. If all you want is a better spelling/grammar checker, I highly recommend it.
You can also run your own local instance for the in-browser checking, which is handy for me as I need to be careful about sending text off to another company in another country (due to both client security requirements and personal paranoia!).
You don't get the AI based extras like paraphrasing, and the other bits listed in as premium only (https://languagetool.org/premium_new), but if you install the n-gram DB for your language (https://languagetool.org/download/ngram-data/) I found it at least as good as, for some examples better than, Grammarly's free offering last time I did a comparison.
