How to use

  1. Add cards one by one or paste a list: term ; definition.
  2. Study: reveal the answer and rate how easy it was. Hard cards come back sooner.
  3. Take a quiz with multiple choice, and check Progress to see what is mastered.

FAQ

Where are my cards stored?

Only in this browser on your device. Nothing is sent to a server. You can export a JSON backup and restore it later or on another device.

How does the schedule work?

Each card has a level. A good answer moves it up and increases the pause before the next review; a wrong answer sends it back to the start.

Do I need AI or an account?

No. The trainer works offline without AI and without sign-up.

Can I use it for any subject?

Yes: words, dates, formulas, laws, medical or IT terms. Anything with a term and an answer.
