Math playground

The TileDown math engine, compiled to WebAssembly, running in your browser. Type TeX; it renders to SVG. No server.

Running math live needs a one-time ~18 MB download of the Swift engine, compiled to WebAssembly. Nothing loads until you ask.

This page downloads a ~18 MB gzipped WebAssembly build of the pure-Swift engine (MathTypeset + TileDown). That weight is exactly why the rest of this site renders math to static SVG at build time: readers never download the engine. Here, you opted in to run it live.
