Upload your course material for a subject, and Learnex breaks it into topics, then generates explanations, quizzes, flashcards, and lessons from what you actually uploaded — not generic content about the subject.

Most uploads are processed within a few minutes. The AI generates topic explanations, quizzes, flashcards, and audio or video lessons automatically — you can start studying shortly after uploading.

A Trail is a complete study path for a subject — a structured sequence of topics, each with explanations, quizzes, and flashcards generated from your uploaded material. You progress through topics as you hit mastery.
