Anti Noise Feynman: AI Study turns scattered information into knowledge that sticks. Save an article, drop a note, snap a screenshot — Anti Noise distills each capture into a Feynman-style summary, then automatically generates spaced-repetition flashcards from the ideas worth remembering. Open the app each day to a fresh set of skills worth learning, and review just the cards due today. — DAILY KNOWLEDGE Every day, Anti Noise hand-picks 3 "skills worth learning in the AI era," matched to your interests, role, and experience. Tap any one for an instant explainer and turn it into flashcards — a reason to open the app and grow a little every day. — FEYNMAN AI SUMMARIES Every capture gets a clear, five-part breakdown: a simple explanation, an analogy you'll remember, knowledge gaps to fill, real-world examples, and a deeper question to keep thinking. Powered by advanced AI vision (URLs, text, and images). — LAYERED FLASHCARDS The AI builds each deck along Bloom's taxonomy — Recognize, then Recall, then Apply — so you move from spotting a concept to actually using it. SM-2 spaced repetition (Anki-classic) schedules reviews so you only see what you're about to forget. New here? You start with sample decks ready to review on day one. — DEEP LEARN (PRO) Turn any deck into a 7-day mastery course. Each day is a short lesson: a plain-language explanation, a few new flashcards (Recognize → Recall → Apply), and a prompt to use the idea for real. Go at your own pace — all seven days are open from the start. — DAILY DASHBOARD See today's picks, your captures, your streak, and what's due to review. One screen, no clutter. — PRIVATE BY DEFAULT Captures live on-device first (SwiftData). Optional Firebase sync mirrors across your devices. AI runs on our secure servers — no API key to manage, and we never sell your data. — SHARE EXTENSION Send a link from Safari, share an image from Photos, drop text from any app — Anti Noise captures it without leaving the source app. — FREE & PRO Free: 3 captures/day, 10 AI summaries/month, plus daily learning picks. Pro: unlimited captures and summaries, 7-day free trial on first launch. Pro monthly and annual options available. Anti Noise is built for solo learners, knowledge workers, and students who want to absorb the web instead of drowning in it.

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. Download Unfog and find out whether you truly understand what you just read.
