Stop passive reading. Start real learning. Whether it is a 2-hour college lecture, a dense research PDF, a YouTube tutorial, or a business meeting audio, MasteryAI transforms your raw content into structured, high-retention study notes built around how the human brain actually retains information. Go beyond simple summarization. MasteryAI integrates science-backed learning methodologies like the Feynman Technique, Active Recall, and Spaced Repetition into a seamless digital study workflow. THE PROBLEMS WE SOLVE - Information Overload: You consume hours of content but retain only 20 percent a week later.

AI supports your study from setup to repeated review. Turn the materials you already use into active-recall study sheets. AI Study Sheet helps you prepare, review, and repeat by automatically finding key terms, creating masks, and keeping your study moving with Auto mode. ■ Turn your materials into study sheets with AI Import pages from your camera, photo library, or PDFs. AI finds important terms and creates study masks automatically. ■ Study with Auto mode Focus on recalling the answer instead of tapping through every question. Auto mode highlights the current mask, reveals the answer after a countdown, and moves on to the next question. ■ Import pre-marked materials Already use red text, orange text, or highlighters for studying? AI Study Sheet can detect marked areas and turn them into masks you can review. ■ Import multiple pages at once Add multiple photos or multi-page PDFs. Pages are processed one at a time, so you do not need to wait for the entire batch to finish. ■ Keep studying while imports run Return to your library and review other materials while new pages are being processed. Spend less time waiting and more time studying. ■ Built for active recall Reveal answers, check what you remember, and keep moving through your material. Rate each page as Remembered, Unsure, or Not remembered to support your next review. ■ Repeat until it sticks Keep your study materials in your library, find them again later, and return to what you need to review. ■ Share study materials Pro users can send study materials to others. Received materials can be added to the library and used for study. The free version lets you save up to 3 pages at first.
