Phrase.it is a free image manipulation service that I tried out earlier this year. Phrase.it allows you to add speech bubbles and some basic Instagram-like effects to your pictures. When I first tried Phrase.it you could only add effects and speech bubbles to one image at a time. Now you can upload and work with multiple images in the same Phrase.it project.
To use Phrase.it just upload a picture and choose a speech bubble.
Drag your speech bubble into place then type your text. You can change
the font style in your speech bubbles. Click the "add more drama" button
to add one of four image shading effects. When you are done adding text and drama to your images click the "preview and save" button to download a strip of your pictures.
Applications for Education
Phrase.it does not require any kind of
registration to use which means that students don't have to have email
addresses to use it. Students can download their completed images and
use them wherever they like. Phrase.it could be a good service for students to use to create stories in a comic strip style.
