A spaced repetition app that starts from your notes
The method works; the setup is what kills it. Cardemio removes the typing: upload a chapter, get a deck, and let your score history tell you what to review next.
MAKE A DECK FREECARDS WITHOUT TYPING
PDFs, slides, and pasted notes become decks in minutes, so the method survives contact with a busy week.
REVIEWS ON A SCHEDULE
Learning paths show the last time you opened each deck, so the one you are avoiding is obvious.
PROOF IT IS WORKING
Score history, streaks, and time spent per deck turn retention into something you can see.
THE METHOD, IN FIVE INTERVALS
- Review new cards the same day you learn them.
- Again the next day.
- Three days later.
- A week later.
- Two to three weeks later, then retire what stays easy.

COMMON QUESTIONS
Is spaced repetition really better than rereading?
Yes, and it is not close. Retrieval practice at growing intervals produces far better long-term retention than rereading, which mostly builds familiarity. Our spaced repetition guide covers the research in plain language.
Do I need to make cards by hand first?
No. Upload a PDF or paste notes and Cardemio generates the deck, so your time goes into reviewing rather than typing.
Is it free?
Yes. The free plan includes deck generation and study modes. Paid plans add larger PDFs and more decks per month.
START THE SCHEDULE TONIGHT
One chapter is enough. Upload it and run your first review before bed.
