Cliperado works like a search engine spider. But instead of extracting the contents, it takes full page screenshots.
You decide of which pages it may take screenshots. This can be pages behind a login screen. Because you can let Cliperado fill out forms or click on buttons just like a normal user would.
Once you have the screenshot, you can clip sections from it and add some markup, like arrows or a highlights. This makes it easy to create step by step instruction clips for your help guides.
Every clip has its own, unique url, this url never changes. So when the screenshot changes, the images on your site are up-to-date as well.
Cliperado compares the old and the new screenshot and highlight the changes. So you don't have to hunt down changes.
