Dipity is a great timeline creation tool that allows users to incorporate text, images, and videos into each entry on their timeline. Like most good web tools, Dipity has a collaboration option and has multiple options for sharing your timelines publicly or privately. Each entry to a Dipity timeline can include multiple types of media which allows users to add more detail and information than can be included in a traditional timeline.
