NoteFren

NoteFren is an AI study companion for students and lifelong learners. Turn notes, PDFs, slides, recorded lectures, and YouTube videos into flashcards, quizzes, and study games. Review with spaced repetition, explain topics out loud to find gaps in your understanding, and turn notes into audio for studying on the go. Available on the web, iPhone, and iPad, with a free plan and optional Pro subscription. Students can start with their existing class materials rather than writing every study card by hand. NoteFren supports active recall through question-and-answer cards, multiple-choice and true/false quizzes, matching games, and other review modes. Its explain-it-out-loud feature asks follow-up questions to help learners notice the parts they need to practice. Handwritten note scanning is available in the iPhone app, and study materials sync between the web and mobile apps. A free plan lets learners try the core study workflow before choosing whether to upgrade.
