PowerMockup provides a large collection of user interface elements and icons made entirely out of PowerPoint shapes. With these elements you easily can create screen prototypes of mobile, web, and desktop applications—right inside PowerPoint! PowerMockup’s instant search feature makes finding the right shapes an easy task. As you type, the list of shapes automatically filters until you get what you are looking for. PowerMockup also recognizes synonyms so that a search for “Input” yields results including “Text Box” and “Text Area” items.
