Stop rereading the same chapter and hoping it sticks. Unfog turns lectures, PDFs, and videos into real understanding — you explain in your own words, and the app shows exactly what still needs work. The Feynman method, built for your phone: add material, explain it simply (as if to a friend), get honest feedback on gaps, then revise with quizzes, flashcards, and mind maps. WHAT YOU GET ▸ Learn by explaining — voice or typed answers ▸ Honest gap feedback — strengths and weak spots, so revision stays focused ▸ Smart notes — clear summaries from your source material ▸ Quizzes and flashcards — generated from your topic, in your language ▸ Mind maps — see how ideas connect at a glance ▸ Many sources, one place — PDFs, scans, recordings, YouTube, links, pasted text ▸ Shared study spaces — revise with others, like a group session before exams ▸ Built for real sessions — mobile-first, dark mode, English and Polish HOW IT WORKS 1. Add material — a chapter, lecture, or lesson 2. Read smart notes to get oriented 3. Explain it simply, as if to a friend 4. Identify gaps and retry until it sticks 5.
