Gandi IDE is a high-level block-based visual programming language and website aimed primarily at children as an educational tool, with a target audience of ages 8 to 16. Users on the site, called Scratchers, can create projects on the website using a block-like interface. Projects can be exported to standalone HTML5, Android apps, Bundle (macOS) and EXE files using external tools. Scratch was conceived and designed through collaborative National Science Foundation grants awarded to Mitchell Resnick and Yasmin Kafai. The service is developed by the MIT Media Lab. Gandi IDE is taught and used in after-school centers, schools, and colleges, as well as other public knowledge. is based in Scratch. Gandi IDE takes its name from a technique used by disk jockeys called "scratching", where vinyl records are clipped together and manipulated on a turntable to produce different sound effects and music. Like scratching, the website lets users mix together different media (including graphics, sound, and other programs) in creative ways by creating and 'remixing' projects, like video games, animations, music, and simulations.
