Flashcards

Create your cards in seconds

Write your own question and answer. No uploads, no waiting.

Real spaced repetition

A box system (the Leitner method) decides when it’s time to review each card, based on whether you knew it or not.

Track your progress

Flip the card, decide whether you knew it, and the system adjusts how often you’ll see it again.

No sign-up, no waiting

Your cards are saved right in this browser, ready to use instantly. No accounts, no passwords.

Say goodbye to boring study sessions.

Flashcards aren’t just notes: they’re a mental training tool. By forcing your brain to actively recall the answer before seeing it, you lock in knowledge far more deeply than with traditional reading. It’s the most efficient way to memorize dates, formulas, vocabulary, or complex concepts, without the hassle.

What do you get out of it?

  • Smart repetition: the system shows you the cards you find hardest to remember more often.
  • Visible progress: see how many cards you’ve mastered and how many you still have to review each day.
  • Backup: export your cards anytime so you don’t lose them if you switch browsers.

For Secondary Students:

The easiest way to learn vocabulary, dates, or formulas without even trying.

For University Students:

Master technical terms, formulas, or key authors from your toughest subjects, at your own pace.

For Any Exam:

Prepare for any test by reviewing exactly what trips you up, without relying on scattered notes.

Frequently Asked Questions (FAQ)

Do I need to create an account?

No, never. You can use the tool right away, no sign-up or passwords required.

Where are my cards saved?

Right here in this browser, on your device. Nothing is sent to any server.

Will I lose my cards if I close the browser?

No, they stay saved. You’ll only lose them if you clear this site’s browsing data or switch browsers/devices — for those cases, use the “Export backup” button and save the file.

How does the app decide when I need to review a card?

It uses a box system (the Leitner method): if you say you knew the answer, the card moves to a box with a longer interval; if you didn’t know it, it goes back to the first box so you’ll see it again soon.

Can I move my cards to another device?

Yes, export a backup from the device where you created them and import it on the other one using the corresponding button.
