Spaced repetition, rebuiltYou forget.
It catches you.
Cirello is a spaced-repetition flashcard app scheduled by FSRS-6. Review straight from the real page - a book, a link, a photo. Blank on something and it's back in rotation before you close the tab.
The everyday loop.
Paste a list, drop in images, or link straight to the page you're reading. No forms, no fuss.
A few minutes a day, scheduled by FSRS-6 - an open-source memory model fitted to your own review history.
Blank on something? It's offered right back to you, on the spot - the deck fixes itself.
"You highlight half a book, then never see those highlights again."
The problem with every note-taking app that isn't built to bring things back.
Not another deck to maintain.
Cards can prompt straight from a book, page, or link - not just typed text.
Progress is counted by the week against a target - a quiet day never resets anything.
Blank on a card and it's offered right back to you, on the spot.
Books. Web pages. Photos.
Notes you scribbled yesterday.
Review, without the guilt.
No confetti when you finish. No shame when you skip a day. Progress is counted by the week, against a target - so a quiet day never wipes out a thing.
The app teaches itself.
A short survey, a couple of starter decks, a guided walkthrough on the actual app - not a manual. You're reviewing real material within minutes.
Questions, answered.
Cirello is a spaced-repetition flashcard app. It schedules review of anything you want to remember - words, facts, book highlights, ideas - so it resurfaces right before you'd normally forget it.
FSRS-6 (Free Spaced Repetition Scheduler, version 6) is an open-source scheduling model with 21 parameters that tracks each card's difficulty, stability and retrievability, instead of applying a fixed interval table. Cirello uses it for every review, and the parameters are refit to your own review history once you have enough reviews (at least 1,000 scheduled reviews).
No. Paste a list to bulk-add cards with duplicate detection, or point a card at a real source - a book, a website, an image - instead of typing everything out by hand. You still organize your library into folders, capture is just faster.
It's offered right back to you on the spot, in the same session, instead of waiting for the next scheduled review - the deck repairs itself as you go.
A few minutes. FSRS-6 only resurfaces what's actually due that day - not your whole library at once.
Yes. Reverse mode asks for the front from the back, listening mode plays the front's audio, quiz mode offers four options, and a mixed session blends them. Drill adds extra practice on hard cards, and exam plans pull reviews in before a date you set.
Web today - that is the only version available. iOS and Android apps are planned, with no date yet.
No. The beta is completely free to use, no card required. Further down the road we plan to introduce a subscription to keep the project sustainable long-term - with benefits for early beta users who joined before that.
The app is fully translated into English and Ukrainian today, with more languages planned.
