AI-powered learning tool turns books, PDFs, and topics into personalized quizzes to improve long-term retention

The tool lets users import books, upload PDFs, or select curated topics, then generates AI-created multiple-choice questions from the source material to enable active recall practice.

Features include spaced repetition (revisiting hard questions at optimal intervals), progress tracking with score trends and feedback, and daily practice to build durable knowledge.

Pricing is pay-as-you-go with no subscription: Starter pack ($2 one-time, 50 credits), Growth pack ($9 one-time, 300 credits), and Scale pack ($25 one-time, 1000 credits), where 1 credit equals 1 quiz question.
