Pretty good for language practice
I’m in need of an AI language exchange program, and this seems to be the closest to fitting that. This is expensive. If you could copy the text it would have more value, or if it integrated automatic translations. As it stands I need to remember what it typed in one language, open my translation dictionary, correctly input and see what it meant. Even an ability to copy the text would help. However it does allow testing questions and audio at any time you want, as repetitive as you need to be, and as basic or advanced.
Update February 2023: I used to have a paid subscription to this app. However I discovered how great alternative chatGPT apps are for translation. And many of the apps allow you to copy and paste. The developers here have an opportunity to jump ahead of the competition but will probably lose out.
