Anti Noise has one job: turn the things you save into knowledge you'll actually remember. The whole app is built around a single loop — capture, summarize, remember — with a few features that make the habit stick. This guide walks through each one, in the order you'll meet them.
The short version
Save anything with the share sheet → get a five-part Feynman summary → Anti Noise turns the key ideas into layered flashcards → review what's due each day. Spaced repetition shows you only the cards you're about to forget, and Daily Knowledge, Deep Learn, and Ascent keep the habit going. No API key, private by default.
1. Capture — save anything, from any app
Everything starts with a capture. There are three kinds, and you almost never have to open the app to create one:
- Link — reading an article in Safari? Tap the share icon, choose Anti Noise, done. The full page comes with it.
- Text — highlight a passage anywhere, or paste a stray thought straight into a new capture.
- Image — screenshot a slide, a tweet, a page of a book. Anti Noise reads the image with AI vision, so a screenshot is as good as text.
The trick is the share sheet: from Safari, Photos, or any app, send the content to Anti Noise without breaking your flow. It lands in your inbox, ready to summarize when you have a minute.
2. Feynman summary — understand it in five parts
Open a capture and tap to summarize. Instead of a flat "TL;DR," Anti Noise writes a five-part Feynman summary — the format named after the physicist who insisted that if you can't explain something simply, you don't really understand it:
- Simple explanation — the core idea in plain words, no jargon.
- Analogy — "X is like Y," so it connects to something you already know.
- Knowledge gap — the question the piece raises but doesn't fully answer.
- Real example — where the idea shows up in practice.
- Go deeper — a prompt to keep thinking.
This is the difference between feeling like you understood an article and actually understanding it. Want the full method? See the Feynman technique, explained.

A summary you read once still fades. So Anti Noise turns the ideas worth keeping into a flashcard deck built along Bloom's taxonomy, in three layers:
- Recognize — can you spot the concept when you see it?
- Recall — can you produce it from memory, in your own words?
- Apply — can you use it on a new problem?
You move up a layer only once the one below is solid, so you build from recognition to real fluency instead of memorizing trivia. New to the app? You start with a couple of sample decks so there's something to review on day one.
4. Review — spaced repetition that respects your time
This is where memory is made. Anti Noise schedules reviews with SM-2 spaced repetition (the classic Anki algorithm), which means you only see a card when you're about to forget it. After each card you rate how well you knew it — Again, Hard, Good, Easy — and the app spaces the next review accordingly. A few minutes a day clears what's due; nothing piles up if you stay consistent.
The point isn't to review everything. It's to review the right things at the right time — which is exactly what spaced repetition is for.
5. Daily Knowledge — a reason to open the app
Every day, Anti Noise hand-picks three "skills worth learning in the AI era," matched to your role, interests, and experience level. Tap any one for an instant explainer, and turn it into flashcards just like a capture. It's a small, fresh thing to learn each day — the habit loop that keeps the rest of the app useful.
6. Deep Learn — turn a topic into a 7-day course (Pro)
When you want to go beyond a single article, Deep Learn turns any deck into a seven-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. All seven days are open from the start, so you can go at your own pace — one a day, or binge a few on a slow afternoon.
7. Ascent — a 60-day climb fueled by real learning
To keep the streak meaningful, Ascent turns your learning into a 60-day mountain expedition. Reviewing due cards, completing a Deep Learn day, and keeping your streak all earn elevation; you pass camps along the way and summit a new peak each season. The one rule that matters: only real learning earns elevation — there's no points for hoarding or busywork, because that would defeat the whole purpose of the app.
Free, Pro, and your privacy
The free tier covers the core loop: 3 captures a day, 10 AI summaries a month, and your daily learning picks. Pro unlocks unlimited captures and summaries plus the Deep Learn courses, and there's a free trial on first launch so you can feel the difference before deciding.
On privacy: your captures live on-device first (SwiftData), with optional sync to mirror across your devices. The AI runs on our secure servers — there's no API key to manage, and we never sell your data.
The 60-second version
Save the next thing you'd normally bookmark and forget. Summarize it. Let Anti Noise make the cards. Tomorrow, open the app and clear what's due. Do that for a week and you'll feel the difference between a feed you scroll and a library you actually keep.
