RanGen is described as 'Welcome to RanGen, a space that offers writing prompts and inspirational bursts creators of all shapes and sizes. I'm your host, Ameronis, and I'll be happy to take you on a wonderful, magical journey with the help of my many Gens'.

Other great sites and apps similar to RanGen are Seventh Sanctum (Free Personal), Drawzer (Free), Springhole.net (Free) and Generator Land (Free).
Generator Land is a community of people who enjoy playing with and building random generators. Anyone can use and share the generators they like, but members can also build their own and save what they create. How cool is that?
