QuickDeck Study
Flashcards with real FSRS-6 spaced repetition — free, in your browser, no paywall ever
Make decks and cards, study with Again / Good / Easy, and let the open-source FSRS-6 scheduler decide when each card comes back. Import a Quizlet CSV or paste cards, track your streak and retention per deck. Everything is saved in this browser and nothing is ever gated.
Stored in your browser only. Nothing you do in the web version is sent to our servers. Clear your browser data and it's gone — so export a backup from the in-app menu if you want to keep it.
This app is a community proposal.
Try the full browser version now. We build the iPhone and Android app once 100 people upvote it.
We'll email you once, when it ships. Unsubscribe anytime.

What you can do in QuickDeck Study on the web
FSRS-6 scheduling, faithfully ported
The 21 default FSRS-6 weights, 90% target retention, stability and difficulty per card, lapses on Again — the same maths as the iPhone app.
Study with three buttons
Tap to reveal, then Again / Good / Easy. Each button shows the interval it would schedule before you press it.
Decks and cards in seconds
Name a deck, add question and answer, edit or delete any card, reset a deck’s scheduling, export a deck as CSV.
Quizlet CSV import and pasted cards
Pick a CSV/TSV export or paste one card per line — commas, tabs, semicolons and quoted fields all work.
Stats that say what you actually know
Day streak, retention rate, minutes studied this week, reviews per day for the last 7 days and retention per deck.
Due badges everywhere
Home says how many cards are due today; each deck shows its due count; every card shows NEW, DUE NOW or DUE IN n DAYS.
