Spaced repetition is a learning technique that shows you flashcards at increasing intervals based on how well you know them. Cards you struggle with appear more often; ones you know well appear less. It's backed by decades of cognitive science research.
FSRS (Free Spaced Repetition Scheduler) v6 is the most advanced open-source scheduling algorithm available — the same one used by Anki. It personalizes the forgetting curve per user and optimizes review timing based on your memory patterns, improving retention by up to 30% compared to traditional methods like SM-2.
Forgetless supports OpenAI, Anthropic, Google Gemini, and Mistral for flashcard generation. All four produce high-quality cards — pick whichever you prefer.
