Watch videos with interactive subtitles
Browse thousands of videos — from kids' shows to news and sports. Every word in the subtitles is tappable, so you can look up translations and save vocabulary without leaving the video.

Listen to songs while reading along
Music is one of the fastest ways to internalize a language. Follow along with synchronized lyrics, tap words you don't know, and let the rhythm carry you to fluency.

Immerse yourself in audiobooks
Choose from a growing library of audiobooks with tap-to-translate, chapter navigation, and word saving. Stories are available at every level — from beginner to advanced.

Discover stories you'll love
Browse a curated library of picture books, chapter books, and more — all designed for language learners. Each story comes with audio narration and built-in translations.

Bilingual children's books
Perfect for kids and beginners. Read beautifully illustrated picture books with side-by-side translations. Audio narration helps with pronunciation, and every page is a new adventure.

Review with spaced repetition
Every word you save becomes a flashcard. Fluency's spaced repetition system brings words back at the optimal time so they stick in your long-term memory.

Track your progress, build a habit
See your active days on a calendar, build streaks, and celebrate your consistency. Miss a day? No worries — just pick right back up. Learning should be fun, not stressful.
