    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. "

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

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