Flashcards World
Learn smarter, remember longer.
Flashcards World is a free spaced-repetition flashcard app built to help anything you study actually stick. Instead of cramming, it uses the modern FSRS algorithm to schedule each card right before you would forget it, aiming for a target retention of around 90% so you spend your time on what matters.
Study your way with five distinct modes: classic flip cards, multiple choice, writing, drawing, and audio. Cards can carry images, audio, and text-to-speech, and you can study fully offline with seamless sync across web, iOS, and Android.
It is completely free with an ad-free web experience, and you can bring decks you already own. Import from Anki, Quizlet, CSV, and Excel while keeping your existing scheduling intact, or start from the public library of community decks.
What you can do
- FSRS-powered scheduling— Reviews are timed by the FSRS algorithm to hit a target retention near 90%, so you see each card right when you are about to forget it instead of wasting reps.
- Five study modes— Switch between classic flip, multiple choice, writing, drawing, and audio to match how you learn and to reinforce material from more than one angle.
- Import without losing progress— Bring decks from Anki, Quizlet, CSV, and Excel. Existing scheduling is preserved on import, so you pick up exactly where you left off.
- Community deck library— Browse a public library of decks shared by other learners and start studying a topic in seconds instead of building everything from scratch.
- AI card generation— On the mobile apps, generate cards automatically from your own text or PDFs, turning notes and documents into ready-to-study decks.
- Rich media and offline sync— Add images, audio, and text-to-speech to your cards, study completely offline, and sync your progress across all your devices.
