Recipes

Jobs that take more than one tool

A recipe is a fixed list of steps for something people do often: paste once, run, and read every intermediate result. Text recipes run on the page. Image and document recipes walk you through the tools in order, handing the file forward. Either way, nothing leaves your browser.
