Eon's dad built something special for learning Chinese: a tool where Eon draws a character's strokes with a digital pen, and an AI turns them into a vivid picture. It makes a brand-new character impossible to forget.

The simplest character

The Chinese word for one is (say it like "ee" — ). It's the easiest character there is: a single horizontal stroke, left to right.

The real trick: imagination

Writing one line over and over is boring, and boring things slip out of your memory. So Eon's dad asks the magic question: "What does this stroke look like?"

Eon's answer: a snake! (His dad first guessed a fallen tree.) So Eon draws the single stroke, and the AI renders it into a cute blue snake — with a little tongue. Now, whenever Eon pictures that snake, he remembers .

Turning a fact into a picture is called a mnemonic — and it's one of the best memory tricks there is.

Same stroke, different picture

Want it to be a fallen tree instead? Just change the words you give the AI — and the color (brown for a tree trunk). One stroke, many memory-pictures. You choose the one that sticks for you.

Try it

Look at . What does that single line look like to you — a snake, a stick, the horizon? Draw your own version. The picture you invent is the one you'll never forget.
