Features
Weakness Decks
Automatically builds a focused deck from the flashcards you struggle with most: low retention, high lapse count, the ones that keep catching you out. Stop wasting time on what you already know.
Gap Detection & AI Study Prompts
Identifies the decks and cards you struggle with most, ranked by fail rate. Generates personalized study prompts you can use with ChatGPT, Claude, or any AI assistant, targeting exactly what you need to review.
AI Flashcards from PDF
Upload your lecture slides, PDFs, or documents. AI reads the material and creates study-ready flashcards in five styles: terminology, conceptual, applied, mixed, and cloze. From a 50-page PDF to a study deck in seconds.
MCQ Quiz Generator
Automatically generate multiple-choice quizzes from your flashcard decks. AI creates plausible distractors from your actual course material. Single and multi-correct formats with partial scoring. Practice in real exam conditions.
AI Answer Evaluation
Type your answer in your own words and get a percentage score based on key concepts covered. Pro users get full AI evaluation that checks understanding, not just keyword matching.
Study Analytics & Forecasting
Track your retention rate, study streaks, rating distribution, and card states over time. FSRS workload forecasting simulates your review schedule and estimates when you'll master each deck.
Know what to focus on before the exam
Gap detection ranks the decks and individual cards you struggle with most by fail rate. Then it generates ready-to-use AI study prompts targeting your weak areas. Paste them into ChatGPT, Claude, or any AI assistant for a focused tutoring session on exactly what you need to review.

1 credit spentWhat is the primary function of mitochondria?
To produce ATP through cellular respiration, providing energy for cell processes
Define oxidative phosphorylation
The metabolic pathway where electrons transfer through the ETC to generate ATP
What role does the inner membrane play in ATP synthesis?
Houses the electron transport chain and ATP synthase for chemiosmotic coupling
Compare aerobic and anaerobic respiration
Aerobic uses oxygen, yields ~36 ATP. Anaerobic does not, yields 2 ATP
