Forget about forgetting
The future of spaced repetition has arrived.
The Flashcard of Tomorrow
Synapdeck was built by seasoned spaced-repetition addicts who understand how useful flashcards can be — and how much of a pain existing flashcard software can be to use. With Synapdeck, you’ll spend less time designing flashcards and more time reviewing them.
Say Goodbye to Cramming
Synapdeck uses the power of spaced repetition to help you remember things for years to come, not just on the next quiz. Every time you get a card right, Synapdeck will increase the amount of time before you see it again — and, if you blanked on the answer, you’ll see it again a bit sooner. Spaced repetition is what allows med students, game show gurus, and polyglots to learn thousands of facts and words efficiently without forgetting them a week later. Synapdeck uses FSRS-6, the state-of-the-art spaced repetition algorithm, so you can learn more efficiently than ever before.
Intuitive Field-and-Template Architecture
Like Anki, Synapdeck lets you design custom notes with field-and-template architecture, so you don’t need to create separate cards for hortus → garden and garden → hortus. No more raw-metal HTML or JavaScript: Synapdeck lets you design cards in Markdown. Still a bit perplexed? Prompt Synapdeck’s built-in AI agent to do the busywork for you, so you can get right back to studying.
A Backup for Your Brain
Synapdeck understands that your mind stores knowledge as an interconnected web and not just a pile of random factoids. You can define which cards are prerequisites of other cards (even across different decks), so you’re not tested on buffering systems until you’ve got the basics of pH down.
Advanced Derivation Methods
No more switching keyboards or constant copying-and-pasting just to review Hebrew or Sanskrit. Synapdeck has more than a dozen built-in derivation methods so you can get <كِتَاب> just by typing <kitaab>. Not a language learner? Derivation methods can also be used to produce chemical diagrams from SMILES notation or an audio snippet from a tone sequence — or you can design your own.
