Cards

A card has a front (the word, phrase or sentence) and a back (its meaning). Cards you add with the extension also keep the video, the line and the second it came from.

Cards you type yourself can have an image instead of a scene.

  • Word · from a videooutfitdas Outfit, die Kleidung
  • Sentence · from a videoYou can’t wear sweatpants to a job interview, can you?Du kannst doch nicht in Jogginghose zum Vorstellungsgespräch gehen, oder?
  • Word · typedder Schlüsselthe key

Spaces

Spaces keep different goals apart, for example English from videos and IELTS Speaking. Each card belongs to one space. Cards from the extension go to the space you pick in the extension.

Review and ratings

When a card is due, look at the front, try to recall the back, then press Reveal. Rate how well you knew it. Each button shows when the card comes back.

Again
You didn’t know it. It comes back in this session.
Hard
You knew it with effort.
Good
You knew it. Use this most of the time.
Easy
You knew it at once.
Example intervals for a card you’ve reviewed a few times. Each button shows the real interval for that card.

LeitnerPlus schedules reviews with FSRS, a modern spaced repetition algorithm.

Review by source and Practice all

On Review you can pick a source: a YouTube channel, a playlist, a Netflix series or a movie. Review only shows the cards that are due from it.

Practice all goes through every card from that source, due or not. Practice doesn’t change your schedule.

Scenes and listening mode

On a card from a video, press Watch at 0:12 to play the scene in a small player, or Open in YouTube to replay the line in the extension.

Listening mode plays the scene first and hides the text until you reveal it. Turn it on in Settings or from the review menu. It applies to this device only.

Good cards

Small, clear cards are easier to rate honestly and come back at better times.

  1. One idea per card. Split “outfit” and “dress code” into two cards.
  2. Keep the back short. A meaning or two, not a paragraph.
  3. Keep the sentence. Cards from videos already have it; for typed cards, add one.
  4. Use an image when it says more. A photo of a kitchen tool beats a description.
  5. Review a little every day. Ten minutes daily works better than an hour on Sunday.

Images, tags and categories

Cards you type can have an image (PNG, JPEG, GIF or WebP, up to 5 MB). Tags and categories help you find cards later: a category can have up to three levels, such as Grammar › Verbs › Irregular.

Each space has a color, so you can tell spaces apart in lists and filters.

Review history

Each card page lists its reviews: when you reviewed it, the rating you gave and when it came back next.

Shortcuts

Use these while you review.

Shortcuts work when you review on a computer with a keyboard.
