Truly great app. It covers exactly what I need right now because I’m studying Chinese and always checking for grammar mistakes. The tool helps a lot. And the Pass AI feature represents a solid part of my workflow too. Not sure why, but the corrections just feel more accurate than other things I've tried. Best app for this and definitely useful for my studies.

I hate not being unable to turn off dutch, polish and italian in language options. Like ah yes I can totally speak all those language like why can't I turn them off specifically. Language English US I understand not being able to turn off but why these three.

Those languages are only listed as available options. They are not enabled by default and won't be used unless you explicitly select them. There's no need to turn them off because they remain inactive until you choose them. You can write to us via the contact section at any time.
