Language Flashcard Randomizer - Online Vocabulary Trainer

Randomization prevents memorizing order and strengthens true recall. By encountering words unpredictably, your brain builds stronger memory associations, simulating real-life language use where context varies.

Absolutely! Use the "Add Word" button to manually insert new words with translations, examples, and pronunciation. You can also import entire decks via JSON files for bulk uploads.

Spaced repetition schedules reviews at increasing intervals. While this randomizer focuses on active recall and immediate feedback, the "I Know"/"Still Learning" system helps you focus on weak words. For full SRS, export your mastered words and re-import later.

Your current progress and custom deck are stored in your browser's local storage. They will persist until you clear your cache. Use the Export feature to save a backup JSON file.

Many cards include phonetic transcriptions. We recommend reading the word aloud before revealing the answer, then checking the pronunciation guide. Combine with external text-to-speech for the best effect.
