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.
Frex is awesome! I use it to translate between French and English. Frex used more casual language in its translations that you would actually hear in the other language, instead of other translators that use overly formal or simplified language. I'm learning a whole new level of the language with Frex.
