No — you can tap “Try it — no account needed” and start scanning straight away.

An account is what makes your study packs follow you: it backs your work up and syncs it to your other devices. Without one, everything lives only on the device you created it on, and it goes away with the app.

Yes. Open Settings → Link Account and sign in with Apple or with an email and password. Your existing packs, cards and progress move over to the account rather than being replaced. Do this before you delete the app or switch phones — an unlinked guest session cannot be recovered afterwards.

Sign in with Apple, or an email address and password. Google sign-in appears in the app but is not switched on yet — if you tap it you'll see a message saying so. If you forgot your password, use “Forgot password?” on the email screen and we'll send a reset link.

Make sure you're signed in to the same account on both devices — guest sessions don't sync. If you are signed in and something is still missing, the device may have been offline when you created it; open the app with a connection and give it a moment.

Credits are what the AI work costs — scanning pages and generating flashcards, quizzes, summaries and tutor replies. The app shows the cost before you confirm, so nothing is ever spent by surprise.

Your monthly allowance resets on the 1st. Paid plans also top up a smaller amount every day at midnight. Credits sit in buckets with their own expiry dates, and the oldest ones are always used first — Settings shows your balance, the next refresh, and anything about to expire.

You can wait for the next refresh, buy a top-up, or move to a plan with a bigger allowance. Everything you have already generated stays readable and studiable while you're out — only new AI work needs credits.

Open the plans screen in the app for the current numbers. We tune allowances and costs from time to time, so the app is always the accurate source rather than this page.

Tap “Restore Purchases” on the plans screen, and check you're signed in to the App Store with the same Apple Account that made the purchase. If it still doesn't appear, email us with the receipt and we'll sort it out.

Settings → Manage subscription takes you straight to Apple's subscription screen, where upgrades, downgrades and cancellation all happen. You can also get there from the Settings app → your name → Subscriptions. Cancelling stops the renewal; you keep the plan until the period you already paid for ends.

Purchases go through Apple, so refunds do too — request one at reportaproblem.apple.com. If something in the app went wrong, tell us as well and we'll help.

Photos of textbook pages, handwritten notes, printouts, and PDFs. Good light and a flat page make a real difference to what the AI can read. How many pages you can put through in one go depends on your plan.

Usually that traces back to the source: blurry photos, cropped edges, or a page that's mostly diagrams give the AI little to work with. Rescanning that page more carefully is normally enough. If a specific pack keeps coming out wrong, send it to us — that's genuinely useful for improving the app.

One person creates a room from a study pack and shares the six-character code; everyone else taps “Join with Code” and plays a live quiz built from that material. On the free plan, hosting a room costs credits; paid plans host for free. Joining someone else's battle never costs anything.

The app is translated into 52 languages and follows whatever your device is set to. The AI works from your material in its own language too — you don't have to study in English.

iPhone and iPad on iOS or iPadOS 18 and later, with a layout built for the bigger screen. Your subscription covers every device you sign in on.

Pages you scan are sent to our servers to be processed into cards, quizzes and summaries, and your study packs are stored with your account so they can sync. The Privacy Policy has the full detail.

Email us from the address on the account and we'll delete it along with your packs and scans. You can remove individual study packs yourself at any time from the pack menu.
