About Vocabuo
Vocabuo is a vocabulary-focused language learning app designed for learners at proficiency levels A1 to C1 studying English, Spanish, French, Italian, German, or Swedish. The app centers on spaced repetition (SRS) flashcards with multiple card types, including sentences, dialogs, audio, and definitions, alongside practice modes such as typing, speaking, or tap-to-reveal. Users can learn from real-world content by extracting words from YouTube subtitles, web pages via a built-in reader, and eBooks or texts, which are then converted into review cards. Vocabuo offers ready-made word lists aligned with proficiency and exam preparation standards, including frequency-based lists and the ability to skip already known words. The app includes an AI tutor feature that provides explanations, built-in dictionaries, Linguee citations, and support for grammar cards, along with detailed progress statistics. It is available on both mobile and web platforms and operates on a freemium model, offering free basic access with optional premium subscriptions.
