It becomes cards that test you, and every card knows where it came from.
Reviewing, exams and games are free without limit.
Where a card comes from
Cards carry their origin: what captured it, the day it arrived, and the note it came from. Weeks later, when a card surfaces and you cannot place it, you can go back to the thing it came from.
The line at the foot of the card is the source. It is on every card, in every session. The four keys print what pressing them will do before you press.
Most study apps start after the hard part
They assume the material is already typed in, already organised, already yours. Quat starts with what you already have: the page, the PDF, the lecture.
Photo
Point your camera at a textbook page, a whiteboard, a handout, or your own handwriting. Quat reads the text off it.
File
Choose a PDF, Word, PowerPoint or Excel document. Quat reads it and turns it into a note and cards.
Link
Paste a URL. Quat fetches the page, reads it, and summarises what matters. It reads the actual page, so it cannot invent what is not there.
Audio
Record a lecture, a seminar, or yourself talking through a topic. Quat transcribes it and pulls out what is worth remembering.
Study one subject at a time
Put each course in its own folder, and every card made from it stays there. When an exam is coming, sit a practice exam on just that folder, and see what needs work before you start.
Folders
When you save a capture, choose its folder or make a new one right there. Cards made from a note stay in that note's folder.
Practice exams
Pick all your material or one folder, then 10, 20, 40 or every card. Mark yourself right or wrong; the misses go back into review with one button. The exam never changes when your cards are next due.
Add to a note
When a topic continues, add the new capture to the bottom of a note you already have. Its cards join that note, and making cards again uses only the new part.
Review that ends
Spaced repetition schedules each card for the day you are about to forget it. When the day's cards are done, the session ends and tells you so. It does not invent more work to keep you in the app.
It celebrates what you actually did — a finished session, a level earned — never the mere fact that you opened the app, and nothing is locked behind a streak. Every number is set in a monospaced face with tabular figures, so counts and intervals stay legible at a glance.
Screens
Private by default
No account. No sign-up. Your notes and cards are stored on your device, not on a server.
- Nothing leaves your device unless you ask for it: a capture sends what you handed it, a tutor question sends the notes it answers from, and a shared deck is sealed on your device before it goes
- No analytics, no tracking, no advertising
- The App Store product page reads "Data Not Linked to You"
- Everything except capture works offline
What it costs
Everything that happens on your device — reviewing, exams, games, writing and editing your own notes and cards — is free without limit. A subscription raises the monthly ceilings on the parts that call a model: capture, the tutor, and card generation. $9.99 monthly or $79.99 a year, billed through your App Store account. It renews until cancelled, which you can do at any time in your account settings.

- Tags, and search across your notes and cards
- Matching, speed round, quiz and a study timer
