Today, sorted for you
Today shows what's due in each deck. The longest-overdue cards come first, and Review all runs every deck in one session.
Flashcards with spaced repetition
Review today's cards. Ruled remembers the rest.
A flashcard deck that lives in your browser. Each card comes back just before you'd forget it, scheduled by the SM-2 method. No account, no settings, nothing to install.

The schedule
One day, then six, then longer every time.
Every time you remember a card, Ruled waits longer before showing it again. Grade it Good seven times and it comes back after 1 day, 6 days, then 15, 38, 95, 238 and 595. That's seven reviews across nearly three years. Forget it once and it starts again tomorrow, so you relearn it before it slips.

How it works
Three steps, and only one of them is daily.
-
Make a deck.
Type cards in, front and back, with line breaks kept. Or import a CSV from a spreadsheet or a classmate.
-
Review what's due.
Open Ruled once a day. See the front, recall, show the answer, grade it. Space and keys 1 to 4 do it all.
-
Ruled does the scheduling.
Each grade sets the card's next date with SM-2. Cards you know drift away; cards you miss come back tomorrow.
What's in the box
Small on purpose.
No pile-ups
At most 20 new cards per deck a day, so a 2,000-word import arrives a little at a time.
Grades that show their result
Each button tells you when the card would come back before you press it.
CSV in, CSV out
Import any CSV with front and back columns. Export keeps every card's schedule, so a backup brings your progress back exactly.
Yours, on your device
No account and no server. Your decks live in this browser's storage, and nothing is sent anywhere.
Keyboard and screen reader ready
Space to show, 1 to 4 to grade. Focus never gets lost, and every save is announced.
Easy on the eyes at night
Light and dark follow your system. With reduced motion on, the card just appears instead of flipping.
The real thing
This is the app. Go on, make a deck.
It runs right here, the same as at app/index.html. Anything you make is saved in your browser and will be waiting when you open Ruled.

What it doesn't do
- No sync between devices. Export a CSV to move or back up a deck.
- Text only: no images, audio or cloze cards.
- No undo for a grade, and no stats or charts.
- No settings to tune. The 20-new-cards limit and SM-2 are fixed.
