Put a real, interactive, correct calculus visual on any page — your class site, an LMS, a blog, a Notion doc. Type a function, copy one line of HTML. Free, no account, no tracking of your readers.
The link underneath is the attribution — please keep it. It is the only thing we ask in return, and it is what lets other people find the tool.
The picture is drawn by a deterministic engine from the actual function — not sketched by an AI. Intersections, areas and tangents are solved, not guessed.
Curves draw themselves in, Riemann rectangles refine, points ride the curve. It is a live widget, not a screenshot of a graph.
One iframe. No script to install, no account, nothing to configure. It resizes to whatever box you put it in.
The widget is driven entirely by the URL, so you can generate embeds programmatically.
The s parameter is a base64-encoded scene: a small JSON object with
functions, an optional domain,
and optional extras like shade, riemann,
polar, field or
analysis. Build one here, then read the URL to see the shape.
