Vocabuo

Vocabuo is a mobile and web app for learning foreign-language vocabulary. Users create flashcards from content they already read or watch, including websites, YouTube videos, eBooks and text, and review them with a spaced-repetition algorithm that schedules cards by difficulty. The app also offers ready-made word lists aligned with CEFR levels (A1 to C2), grammar cards, example sentences, an AI tutor and progress statistics. Courses are published for English, Spanish, French, German, Italian and Swedish.
