Creately - Online Diagramming and Design is a joy to use. Its designed for ease of use and collaboration. It takes 'easy' to a whole new level by intelligently adapting to the kind of diagram you are drawing. Creately has been designed so you can draw just about anything, fast and easy.

If you want to plan out a project, share code design, or craft a funny flowchart, Creately is a free webapp that offers a no-software tool with a nice and easy learning curve.

Most of Creately's diagram and illustration tools, ranging from dead-simple flowcharts to circuit diagrams, are free for signed-up users and allow sharing, embedding, publishing, commenting, and other collaboration tools for up to five people on publicly available works (paid accounts get more shared users and private postings). Like so many web tools, it strips down the interface of desktop offerings like Visio and makes it easier for first-timers to get a grasp on things. Click on a shape or line in your Creately chart, and a context menu offers all the options of moving, reshaping, resizing, or whatever else you can do with it.

Creately is free to sign up for and use. Creately [via TechCrunch]
