Storybird - storybird.com

This tool reverses visual storytelling by starting with the artwork and creating a story from the images. The website has a library of artwork to chose from and a very clean, easy to use interface. There is also the option for teachers to manage students and create a class library of stories. 

This tool could be used in creative writing and enhancing the use of imagination at any grade level. 

Students that have difficulty finding a starting place would find this approach helpful. It would also reduce barriers for students who have a hard time keeping themselves on track. The student has the ability to choose and write about whatever artwork interests them. 

There is no required age of users and an email address is not required.
