|A browser-based mind-mapping application that supports simultaneous, multi-user editing with chat amongst users online. It has an organic appearance and allows nodes to be positioned manually without the program jumping in and reformatting the map when you release a dragged node. This is one of its most useful points - some other mind mapping programs give this freedom, but most do not.
Control of the appearance of text in nodes uses Markdown, and it also supports LaTeX for mathematical notation. Nodes can also have web links and images attached.
Coggle can make a new map from an existing FreeMind (.mm) file, and it will retain the basic structure and any colors in the FreeMind map, but not much else.
The most important thing to know about Coggle is that there is a hidden help area. Once you have signed in and opened a map, or new map page, you'll see that there is a very (very) faint gray bar down the left edge of the window. Click on that, and a narrow information panel appears with a guide to basic operation.
There is a 'How To' guide to all the features here: http://bloggle.coggle.it/category/how-to/
Markdown usage is described here: http://bloggle.coggle.it/coggle-markdown-reference/
Source of other help text, the delightfully-named Coggle Bloggle: http://bloggle.coggle.it/
There's an example map here: http://bit.ly/15dpiyD
Maps are editable on an iPad when opened in Safari, though it needs time to get used to it.
Maps can be embedded on web pages.
