   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.

   DeepL Write vs Grammarly Comments

   Negative comment by Guest · Feb 3, 2025

   DeepL write isn't an extension. This significantly reduces productivity, and can make it look like you've AI generated your whole document.

   Positive comment by AndrewIaz · Jan 29, 2023

   DeepL Write is made by the awesome DeepL company that has also made DeepL Translate, both tools being by far more efficient and capable than competitors. They use Deep Learning extensively to continuously improve their products. Being free and privacy-focused, your documents are your reputation are safe. ;)
