is the study system built around how you naturally learn — write with Apple Pencil, then let spaced repetition and AI-powered scaffolding guide you to long-term mastery.
Notes pile up across classes and subjects but nothing connects to a study method. You capture everything and retain nothing.
Hundreds of pages of handwritten notes with no way to find specific content or link ideas across them. Your best insights are lost in the pile.
No tracking, no consistency, no way to build good study habits. You cram before exams and forget everything after.
Handwritten notes across classes and notebooks but no way to turn them into structured study material without retyping everything.
Passive rereading is one of the least effective study methods. 70% of material is forgotten within 24 hours without active review.
GoodNotes for writing, Anki for flashcards, Notion for organizing. Context-switching between three apps breaks the learning flow.
— one continuous flow. No app-switching. No retyping.
Take notes naturally with Apple Pencil. Full-feature handwriting with the tools you'd expect — connected to everything that follows.
Smart tagging links ideas across notes and decks. Find everything related to a topic instantly. Your knowledge, organized.
One tap to create a study-ready flashcard from your handwritten content. No retyping. No context-switching.
FSRS spaced repetition schedules your learning at the optimal moment — just before you'd forget. 20-30% fewer reviews needed.
AI surfaces connections across your notes and prompts you to see patterns you might miss. The understanding is yours — AI just lights the path.
is built to help you learn.Full-feature handwriting with the tools you'd expect — connected to everything that follows.
AI surfaces connections, suggests structure, and prompts you to think deeper. Your notes, your thinking — AI just asks better questions.
Select handwritten content, tap once, get a study-ready card. No retyping required.
Tag concepts across notes and decks. Find everything related to a topic instantly.
The most advanced open-source scheduling algorithm. A 21-parameter model trained on 500M+ reviews — timed to when you're about to forget.
Handwriting activates deeper cognitive encoding than typing — engaging motor, visual, and spatial systems simultaneously. doesn't replace how you naturally learn. It amplifies it.

Get started with the basics.
The full experience.
For power learners who want it all.
is built Apple-first. Your notes, flashcards, and learning data live on your iPad and iPhone — not on our servers.
Your notes, flashcards, and learning history are stored locally on your iPad and iPhone. We never have access to your learning content.
Sync across your devices via your personal iCloud account. Your data travels through Apple's encrypted infrastructure — we're never in the middle.
We only collect what you explicitly provide — name, email, and account preferences. Nothing more. No tracking, no profiling, no selling data.
You are a learner, not a data point. Our business model is a subscription for a great tool — not monetizing your information.
AI in is a learning assistant, not a shortcut. It prompts, transforms, and challenges — but the thinking is always yours.
AI takes your existing flashcards and transforms them — asking the same concept in different ways. You wrote the card. AI finds new angles to test your understanding.
AI analyzes an entire deck and generates a multiple-choice quiz — connecting ideas across cards to test deeper comprehension, not just memorization.
For Pro-tier learners, AI offers coaching insights — explaining why a card is scheduled when it is, suggesting study strategies, and helping create smart learning events.
AI doesn't do the work for you. It helps you see your own knowledge from new angles, surfaces what you're missing, and schedules the right challenge at the right time. The learning — the writing, the recall, the thinking — that's always yours.
