Language Learning Flashcards | RememberFast - Smart Spaced Repetition

RememberFast is a straightforward flashcard app that uses the SuperMemo SM-2 spaced repetition algorithm to help you learn and retain vocabulary. No account is required — you just open the app, add words or phrases, and start practicing. Everything is saved locally in your browser, so there’s no sign-up friction and your data stays private. The app is completely free right now, with premium features (like cross-device sync and advanced stats) planned for the future.

The core experience is simple: you create flashcards with a word on one side and its translation or definition on the other. RememberFast schedules reviews based on how well you know each card, showing weak items more often and spacing out the ones you’ve mastered. Beyond that, it includes audio pronunciation for most languages, a progress tracker showing your learning history and success rate, and offline support so you can study without an internet connection. The AI extras — text translation and grammar/style correction — are optional and currently in preview. You can use them without a key, or bring your own OpenAI key for more consistent results.

RememberFast is ideal for language learners who want a no-fuss, research-backed study tool without any sign-up hassle. It’s great for building vocabulary in any language, preparing for exams, or simply picking up new words during daily commutes. Because it works offline and saves progress locally, it’s also a solid pick for learners who are frequently on the move or have limited connectivity.
