## What is Unfog?

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. Revise with quizzes, flashcards, and mind maps

Whether you are preparing for exams, learning a new skill, or revising after a meeting, the loop stays simple: capture → explain → fix gaps → revise.

Unfog Pro unlocks full access to study features.
