There is a free trial version which works like the Pro version for 30 days, then it reverts to the free version. There is very little to dislike about the program itself, but there is a lot to dislike about the jingoistic documentation, marketing and support, also there is a lot to dislike about the licensing. TheBrain Technologies have brought out a mapping program which exceeds the capabilities of Cayra in every way, but it is not free. Today I don’t think there is anywhere you can still download Cayra. NET 3.5 broke something in Cayra and it started crashing every few seconds.

The author didn’t release the source code and abandoned the development. Sadly Cayra is no longer viable, it was not being maintained by its author and the original download site lapsed. One of the results of this type of organisation was that your map could be any size and only the things which were one or two connections away from the node you had selected would be shown. It was not organised into a hierarchical tree, anything could be connected to anything else and the map moved to position the selected node into the centre of the screen. It is my opinion that in a mapping program moving the map to keep the node of interest in the centre of the screen is a very useful feature which should be more widely available than it is.Ī long time ago I used a free mapping program called Cayra, it was unlike any of the mind mapping program which I had used before.
