PolyTex

PolyTex is a collaborative LaTeX authoring application. More precisely, it lets several people write course notes in LaTeX format, live.

The document is divided into slides, each of which is managed by one person. The central editor lets you enter your own LaTeX code, and the preview is displayed in real time in the top left-hand corner. There's also a chat function.

I took charge of developing the client side of the project, in HTML, JavaScript and using WebSockets.
