To start, all you have to do is set your native language and target language. Then, just start talking to it in either your native or target language. It'll catch any mistakes you make when you speak in your target language and answer any grammar/vocab questions you have.
It has a translate button, a romanize button (converts any text into the Latin alphabet), and you can highlight words/phrases you don't know in AI responses to have them explained.
I'd appreciate any feedback, thanks!
