A lecture is only useful if you can review it efficiently. Most lecture formats make that hard.
Lectures come in many formats: live classes with handwritten notes, recorded audio, video captures, uploaded slide PDFs, or typed notes from a session. Each format requires a different effort to review — re-watching video, re-listening to audio, re-reading slides. The result is that most lecture material is reviewed once and not retained.
Learnlo accepts all lecture formats and converts each into the same study pack: a structured summary, key ideas, study notes, flashcards, a quiz, and a practice exam. Whatever format your lecture arrived in, your study pack arrives in 90 seconds.
