Active Recall
Flashcards that actually work
Create and study flashcard sets with a distraction-free review experience. Build your own sets from scratch or generate cards in seconds using AI - then study with a flip-card system that builds real memory through active recall.
Create sets in seconds
Add a front, back, and optional source citation for each card. Organise sets by module or topic.
AI-generated cards
Create manual flashcards on every plan. AI-generated flashcards from topics or notes are included in Pro and Unlimited, with no monthly generation quota. Core can save one Obiter Library set per account.
Flip-card review mode
Study in a Quizlet-inspired flip-card view. Mark cards as "Got it" or "Still learning" to track your progress.
Progress tracking
See how many cards you've mastered in each set. The system highlights cards you're still working on.
Sync across devices
Your flashcard sets sync automatically between the web app, desktop, and mobile. Study on your phone on the go.
