Answers for learners who want to understand how Lango handles imports, vocabulary, review, accounts, and support before they start.

Both can use it. Beginners can import simpler screenshots or class-note images, while intermediate and advanced learners can bring in images of native material they want to study.
The app is built for multilingual reading practice and includes popular target languages such as English, Spanish, French, German, Italian, Portuguese, Chinese, Japanese, and Korean.
