About this app

Master any language without the friction. Welcome to Flevro—the modern, AI-powered flashcard app designed for efficient, long-term retention.

If you love the powerful spaced repetition of Anki but are tired of dealing with outdated interfaces, complex setups, and tedious manual card creation, Flevro is built for you. We kept the absolute best parts of advanced cognitive science and combined them with a sleek, intuitive mobile experience enhanced by artificial intelligence.

Because learning a new language is already challenging enough—your study tool shouldn’t be.

🧠 Advanced Science Meets Modern Design
Flevro is built from the ground up on the next-generation FSRS-5 (Free Spaced Repetition Scheduler) algorithm. Unlike traditional flashcard apps that rely on older algorithms, Flevro customizes review intervals with pinpoint accuracy based on your unique memory patterns. You spend less time reviewing what you already know and more time mastering what you don't.

⚡ Powered by AI: Create Cards in Seconds
The biggest hurdle in language learning is the time it takes to make quality study materials. Flevro eliminates that friction entirely with powerful, built-in editor tools:

Automatic Translation: No more copying and pasting between translation apps. Type your target word, and Flevro’s integrated AI handles the translation instantly.

Built-in Text-to-Speech (TTS): Master perfect pronunciation from day one. Flevro automatically generates high-quality, natural audio for your flashcards right inside the editor.

🌍 Learn Anywhere, Anytime
Your learning shouldn't stop when the internet does. Flevro offers a seamless Full Offline Mobile Experience. Study on the subway, in the air, or off the grid. The moment you re-connect, your progress seamlessly syncs across the web and all your mobile devices.
