This is basically mad libs where you fill-in the words using the parts of speech as a guide.

The variables are on the right under the "Customize" tab which allow you to fill in your own word. If you are writing a chapter and want to add a blank which is able to be filled-in, look at the variables on the right bottom area of the screen. You can write the code between the { } marks. If you want a new code, for example, a 3rd noun, you can always just write in the code in the story and someone might write it in the variables section later.

Example

Once upon a time there was a person. And they lived in a house. One day he fucked many moist melons quickly. They also had a/an monkey named Asshat as a den of lions. Their annoying neighbor named Pal-ina fucked at the mall when they were hovering too.
