the problem

Drilling words doesn't stick.

Stacks of cards. Front, back, repeat. You ace the quiz on Monday and blank on Friday — because the word never had anywhere to live.

how it works

A word, a scene, a click. Done.

phase 01

The word arrives in a scene.

Not on a card. Inside a moment your brain can picture.

new · phase 01
perfunctory
/pəˈfʌŋktəri/
your professor scribbled "perfunctory" across your essay in red.
phase 02

You guess from context.

Feel out the meaning. That guess is what makes it stay.

she said the apology was perfunctory — and walked away.
Awarm, full of feeling
Bgoing through the motions
Cfurious and cutting
phase 03

It returns when needed.

Right before you'd forget. Fresh scenes, never the same twice.

But how?

Those give you a word and a definition. Your brain gets nothing to attach it to. Dopus drops the word into a tiny scene — a text, a headline, an awkward moment — and you guess the meaning from context. The scene is what makes it stick.
