Do you have, use, or recommend alternatives to Grammarly?

If you are unfamiliar with Grammarly, it is a spelling, grammar, and tone checker and suggester. The free tier is very useful.

I looked into alternatives, and what I found is:

Grammarly is a US-based company. For accounts created in the EU or UK, no content is used to train models. Others have a choice. Targeted advertising (email address to unique identifier) can be disabled.

LanguageTool is owned by a German business (GmbH), but operates under an international business called Learneo (Inc.). The privacy policy is with Learneo and does include data transfer to the US. It's unclear to me whether they operate [with the data] in the US or if that is only for specific or secondary operations and support.

LanguageTool uses third-party US analytics (Google Analytics and Amplitude.

LanguageTool is Open Source, but self-hosting does not include any of the AI features/rules.

DeepL is a German business. The free tier processes your data for training, and you must not submit any personal data.

Do you know of other alternatives that go beyond simple dictionary spell-checking, similar to these services? Ready-for-use service, local, or self-hosted.
