Learn a Language with Your Own Books

Learn a language by reading your own PDF, EPUB or text books: tap a word you don't know and see its meaning in your language; the word is saved with its context and moved into long-term memory with spaced repetition.

Coming soon to the App Store and Google Play.

Tap to understand
