LanguageTool vs Grammarly Comments
Comment by Jan Klass · Apr 20, 2025
Note: Despite being listed here as "Country of Origin: DE, EU", while the website imprint does list a GmbH (German business), the privacy policy does not mention it; it mentions only the parent org Learneo and it includes data transfer to outside the EEA and into the US.

It works anywhere, just fine
Positive comment by cherriesravenclaw · Sep 27, 2021
Open source. Works just as good, if not better than Grammarly, and it's cheaper if you do opt for one of the paid plans.
