Powerful Features for Language Learning
GenDeck combines AI-powered flashcard generation, stunning images, and proven spaced repetition science to help you master any language faster.
AI-Powered Flashcard Generation
GenDeck uses advanced AI to create flashcards that are perfectly tailored to your learning goals. No more manual card creation — just provide a topic and let AI do the work.
Topic-Based Generation
Simply provide a topic like "ordering food in a restaurant," "travel vocabulary," or "medical terminology." GenDeck's AI analyzes your request and generates contextually relevant flashcards with accurate translations, usage examples, and grammar notes. The AI understands nuance and context, so you get vocabulary that's actually useful for real conversations.
OCR Notes-to-Cards
Take a photo of your handwritten notes, textbook pages, or classroom whiteboard. GenDeck's OCR technology extracts the text and converts it into perfectly structured flashcards. This means you can digitize your existing study materials in seconds, turning physical notes into interactive, AI-enhanced learning cards with images and spaced repetition.
Stunning AI Images
Every flashcard can include a beautiful, contextually relevant AI-generated image. Visual association is one of the most powerful memory techniques — seeing a vivid image alongside a word creates stronger neural connections. GenDeck's images are tailored to each vocabulary word's meaning and context, making learning both effective and visually engaging.
Science-Backed Spaced Repetition
GenDeck uses the FSRS (Free Spaced Repetition Scheduler) algorithm — the most advanced open-source spaced repetition algorithm available.
FSRS Algorithm
Unlike older algorithms like SM-2, FSRS adapts to your individual memory patterns. It calculates the optimal time to review each card based on your performance history, ensuring you review just before you're about to forget. This means you spend less time studying while retaining more — the most efficient path to fluency.
Adaptive Difficulty
The algorithm adjusts difficulty ratings based on your responses. Cards you find easy appear less frequently, while challenging vocabulary gets more attention. Over time, GenDeck builds a personalized model of your memory, optimizing every review session for maximum retention with minimum effort.
Optimized Review Timing
Every review is scheduled at the mathematically optimal moment. Too early and you waste time; too late and you've already forgotten. FSRS finds the sweet spot, dramatically reducing the total time needed to permanently learn vocabulary. Most users see 90%+ retention rates.
