Type a sentence, get an animated chart. Drag a slider, watch the wave change. For kids 8–15. Built on a library that an AI agent (Claude, ChatGPT, Gemini) can call directly.
↑ This is the exact bytes an AI agent gets back from one call to glyph_story.
A wave, a spiral, a wiggly heartbeat, a circle that becomes a line. All made by an agent — no drawing skills required.
A figure-eight
Two waves, one sideways, one up-and-down. Together they draw a loop.
A spiral, drawing itself
The line writes itself onto the page like a pen — same trick a math teacher uses on a chalkboard.
Foxes and rabbits
When the rabbits boom, the foxes boom. Then the rabbits crash, then the foxes do. Forever.
A swing that slows down
Push a swing once and let go. Each swing is a little smaller. This is what that looks like in math.
You type something like "show me a sine wave" — to an AI helper like Claude or ChatGPT.
Behind the scenes, the AI calls glyph_story and gets back a JSON recipe — like a cooking recipe but for a picture.
{
"intent": "show me a sine wave",
"audience": "kid"
}
The recipe gets turned into an animated SVG — like the one at the top. Same recipe = same picture, every single time.
The same math behind the sine wave above looks completely different in three dimensions. Drag to spin. Pinch to zoom.
Tap a shape · drag to spin
Plato thought these were the building blocks of the universe. Mathematicians later proved there are EXACTLY 5.
Drag to spin · watch the formula
z = sin(r − t) · e−r/10
The same sin from the hero at the top — but now in 3D, making water-like ripples that radiate outward.
Sliders let you change the shape of the wave. Move them around — see what happens.
Three short math stories. Each one plays out over a few seconds — like a comic strip, but the panels animate themselves.
Watch the circle unwrap. Its edge is exactly 2 × π × radius — every time, no exceptions.
The highest point of a curve. Math has a word for it ("maximum"). So do we — "the peak."
A wave never stops being a wave. The dot rides it forever — that's what "cyclic" means.
Type what you want to see. We'll send you to the playground with the recipe pre-filled.
Glyph is open-source software an AI assistant uses to draw math. Everything here was generated by a deterministic recipe — no surprise behavior, no telemetry, no ads, no tracking, no account required.

This page has no analytics, no third-party scripts, no cookies. The address bar's URL is the only thing that knows you visited.
Every chart on this page comes from a JSON spec that an AI can write. The same spec always renders the same bytes — no model drift.
Glyph ships as a 50-verb MCP server Claude / ChatGPT / Gemini can call directly. The hero animation up top is one MCP call.
