Morso

Morso is a free AI study app designed to help you learn more efficiently. You can type any topic, upload a PDF, or provide a YouTube link to generate a structured course in just 30 seconds. This platform helps you master new subjects through interactive lessons, quizzes, and progress tracking, providing a complete educational experience tailored to your interests or study materials. The design is intentional. Rereading notes feels productive but produces weak retention. What actually works is active recall — being forced to retrieve information before seeing the answer. Morso builds this into every session: each lesson ends with quiz questions you have to answer before advancing. Cognitive science research consistently shows retrieval practice produces 50–80% better long-term retention than passive review. Progress is tracked with XP, streaks, and a mastery percentage per topic. You see exactly which concepts you have nailed and which still need work — not vague "time spent" metrics. Free tier: 2 courses lifetime, 3 lessons per month, no credit card required. Premium: Unlimited courses, 25 lessons per day, PDF upload, YouTube lecture conversion, priority AI generation, and advanced quiz modes. Plans start at $1.99/week, $4.99/month, or $34.99/year. Available on web, Android, and iOS.
