Lessons You'll Actually Want to Play

Reviewing the same card format two hundred times in a row is how studying starts to feel like a chore. Interact mixes five interactive types in one queue and makes every one of them quick and satisfying to play.

Five types, one queue

Flashcards are the workhorse. They're the fastest to make and the most effective per minute of review, so most of your queue will be cards. But an all-card diet gets monotonous, and monotony is what makes people quit.

So every type lives in the same queue. When a quiz or an image occlusion shows up between runs of cards, it feels like a breath of fresh air, and the session keeps its momentum.

Flashcards

Front, back, flip, rate. The spaced repetition classic, and still the most efficient way to memorize almost anything.

Fill-in-the-blanks

A passage with pieces missing. Fill every blank, then check the whole thing at once.

Quizzes

Multiple choice with plausible distractors. Answer with a tap or a number key.

Image occlusion

A diagram, map, or chart with the labels masked, so each region becomes its own recall moment. There's a whole page on image occlusion.

Type the answer

Produce the answer instead of recognizing it, with grading that forgives typos. More on the type the answer page.

Small touches that keep you going

Animations

Cards physically flip. Answers light up the moment you check them. The next lesson arrives instantly, with no page load in between.

Sound effects

A flip sound on the way over and a pop when you land a correct answer. Small, satisfying, and easy to ignore with the volume down.

Keyboard shortcuts

On the web, arrow keys flip and advance, number keys answer quizzes and fill-in-the-blanks, and Enter always does the next sensible thing. You can clear a whole session without touching the mouse.

From desk to couch

The same queue plays everywhere: on the web with the keyboard, in the iPhone and iPad app with a thumb, and on Apple TV with the Siri Remote. Wherever you happen to be sitting, your due reviews are one tap from starting.

Common questions

Do I have to use every type?

No. Plenty of people study with cards alone. The other types earn their place when the material fits, like a diagram that wants to be an image occlusion, or when a long run of cards needs a change of pace.

Who decides what I play?

The built-in spaced repetition system. Each interactive is scheduled individually, and the Learn queue serves whatever is due today.

What are the keyboard shortcuts?

Arrow keys flip the current card and move between lessons. Number keys select quiz and fill-in-the-blank options. Enter flips, checks, or continues, depending on where you are.

Is playing lessons free?

Yes. Playing your queue is unlimited on every plan, and so is creating interactives by hand. AI generation includes 10 free runs a month.
