This tool is absolutely amazing. It is so convenient and great for learning. I love it so much!

Ken I learned Italian


It was very helpful with translating words I didn’t understand. It also gave me a chance to watch videos that were in German and make it seem fluent in my head.

Eva I learned German


This is so cool! I know Spanish (Native), English (C1) and a little bit of Italian, but will use this to learn French. Thank you so much!
