One of its strengths is that it provides a variety of starting templates. These include UML class diagrams, entity relationship diagrams, sitemaps, wireframes, and much more. You can produce almost any chart or diagram you would need in planning the user experience and data model of your application within the Creately web application.

As we started to write the report, we had to decide what UML tool to use. Our most important concern was that the tool has to be cross-platform. Since Creately is web-based, our concern about cross-platform support is taken care of. It can be used to create informational diagrams, flowcharts, organizational charts, UML designs, mind-maps and many other diagram types. The best part of it is its collaboration capabilities.
