Built on the study methods research ranks highest — active recall and spaced repetition.

Making flashcards by hand is the worst part of studying.

You already have the notes, the slides, the PDFs. Turning them into cards is an evening of typing before you have learned a thing — which is exactly why almost nobody does it.

How it works

From notes to memorized in three steps

1Step 1

Add your material

Type a topic, paste your notes, drop in a PDF, share a YouTube link, or photograph a page of handwriting.

2Step 2

AI builds your deck

It reads the material and writes one clear question per idea — the cards you'd have made yourself, minus the evening.

Review until it sticks

Swipe through the deck. Cards you fumble come back sooner; the ones you know get out of your way.

Why not just use a free app?

“Free” usually costs you something

Cram is a paid app with a free trial — no ads, no data-selling, just your cards. Here's the trade most free apps ask you to make.

  • Ads between your study cards
    No ads, ever — the review screen is just your cards
  • Your data monetized behind the scenes to pay for it
    No data-selling — your notes are used to build your cards, nothing else
  • A stranger's deck that might be wrong or incomplete
    Cards built from your own notes, PDFs, and topics
  • Daily "lives" that lock you out when they run out
    Study as much as you want — no lives, no lockouts

Making the deck is the easy part

Spaced repetition

Every card returns at the moment you were about to forget it, and the gap widens each time you get it right.

Exam countdown

Every deck shows the days left, so you always know whether you're on track or behind.

From PDFs, notes, links & photos

Lecture slides and textbook chapters, yes — but also a YouTube lecture, a web article, or a photo of a friend's handwriting.

Tuned to your goal

Tell Cram you're revising pharmacology and it writes pharmacology cards, not vocabulary drills.

Offline & synced

Decks live on the device and sync to your account, so the tube and the plane still count as study time.

Walk into your exam ready.

Set your exam date and Cram paces every review so the material is locked in before test day.

Questions, answered

How does Cram make flashcards?
Paste your notes, drop in a PDF, share a link, or just type a topic. Cram's AI reads your material and writes clear question-and-answer cards for you in seconds — so you can start reviewing instead of building.
What can I turn into flashcards?
Lecture notes, textbook chapters, PDFs, web articles, YouTube videos, a photo or scan of your notes, or any subject you type in — from Spanish vocabulary to organic chemistry to a professional certification exam.
What is spaced repetition?
It's a study method that shows you each card right before you'd forget it, at gradually increasing intervals. It's one of the most efficient, research-backed ways to move information into long-term memory.
Is Cram free?
No. Cram is a paid app — no ads and no data-selling, just a simple subscription with a free trial on the annual plan. You can cancel anytime from your Apple account.
Is my data private?
Yes. There are no ads, we never sell your data, and your study content is never used to train AI models. Your decks sync securely to your account on EU-hosted servers, and you can export or delete everything from the app. See our Privacy Policy for the full details.
Which devices does Cram support?
Cram is built for iPhone and launches on the App Store first.
