User reviews

Life-changing

This app is life-changing if you are trying to learn a foreign language. It lets you read interesting material like web novels quickly with low effort, so you can actually enjoy the story while learning new vocab and grammar, instead of getting tired out from having to use too much effort to read. There are other apps that do dictionary lookup and translation but none have such a streamlined interface and the dual language view. I use it to read Japanese web novels and my vocab and reading speed have been improving a lot. I use the google cloud api key feature to get the best audio and translation quality.
