This is how to make a new sentence generator:
Let's say you want to call your new generator "blue sky", so write "blue sky" in the textbox "Name of new generator" and click the button "Make new generator". Then in the first box that appears at the bottom of the screen write a few beginnings of your sentence, each beginning on a new line. Like this:
The sky The heaven The atmosphere
Then click the symbol for inserting a new part (which will give you a new box), and there you write a few alternatives for the next part of your sentence, each alternative on a new line. Like this:
is blue, has a blue color, is sometimes red,
Then continue to create a new part again, in the same way, and write for example:
which is my favourite color which i like and it is very beautiful
Then finish by clicking one of the disk icons to save it all. The generator is now ready and you can test it and also modify and improve it. In a similar way you can also modify existing ones.
Note that you can protect your sentence generator with a password so that nobody else will be able to edit it.
