    It doesn't work very well. For example, it shows all is good if I type in the following: "Can you do plan by yourself? Yoda I speak like and check grammar I do. "

    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.

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

    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. ;)

    Hemmingway is a readability tool, NOT a grammar checker. It has nothing at all in common with Grammarly.
