What Flashcards World is
Flashcards World is a study platform built around flashcards and spaced repetition. Its Practice mode uses the FSRS algorithm to adjust review intervals according to recall performance. Study modes include audio review, writing, drawing, matching, quizzes, and classic flashcards. Web tools can draft cards from a topic, notes, or a PDF, and users can review and edit those drafts. AI flashcard generation has usage limits, and card creation is separate from spaced-repetition practice. Users can import Anki APKG, CSV, and Excel files, browse community sets in subjects such as languages, science, medicine, music, and history, and share sets by link or QR code. Signing in synchronizes sets and progress across web, iOS, and Android. The mobile apps support creating and studying offline, then synchronize after reconnecting. The free plan provides web study with spaced repetition and no ads; mobile apps have optional paid extras. Flashcards World SL, registered in Spain, builds the service.
