Create an unlimited number of dual card binders, with an unlimited number of dual cards.
A dual card is a card with 2 sides. For each side, you can upload an image, and/or add text in plain text, markdown or HTML. You can choose to have swappable sides.
For a binder of dual cards, you can generate speech for the text appearing on side 1 or 2 of the cards in bulk (text-to-speech feature).

Create an unlimited number of multi card binders, with an unlimited number of multi cards.
A multi card is a multiple choice question. It has 3 parts. The first part is for the question. You can upload an image, and/or add text in plain text, markdown or HTML. The second part is the multiple choice part. You can add 1 to 9 propositions with text (plain text, markdown or HTML). You set the correct propositions by clicking on the corresponding checkboxes. The third part is for an optional explanation of the answer. You can upload an image, and/or add text in plain text, markdown or HTML.

In any binder, you can create dozens of card at once.
You can name and rename your binders.
You can also name and rename your cards if you want to. Card names are practical for sorting your cards by name within a binder. However, card names do not appear in practice sessions.

Each card saves a mastery score.
For dual cards: you indicate whether you master the card or not, by clicking either on the "To review" or "I master" button.
For multi cards: we automatically detect if you got the right answer or not, based on the checkboxes you clicked and submitted.
All these scores are saved and used by specific practice strategies that prioritize cards based on mastery scores.

All of your cards and binders are private by default. No one else can see them.
If you have credits, you can export or import your binders of cards via CSV files. It's simple way for OptiLeague users to share cards.
The format of the CSV to import cards is detailed on the import page when you are logged in with your account.

Practice your cards in your favorite web browser, on your favorite device: Google Chrome, Safari, Firefox and all Chromium-based web browsers such as Brave or Opera. As long as you have internet, you're good to go.

You can tag your binders with 1 or several tags. You can target the binders to practice with by tag.
You can set cards or binders to inactive, so that they are not used in your practice sessions.
You can customize your practice session by setting the practice strategy you want to use.
In practice sessions for multi cards, we also automatically randomize the order of the propositions.
You can see what practice sessions look like on the quizzes page.
