Software for chess problems can be used for creating and solving problems, including checking the soundness of a concept and position, storing it in a [[database]], printing and publishing, and saving and exporting the problem. As such they can not only solve direct mates, helpmates and selfmates, but at times even problems with [[Fairy chess piece|fairy pieces]] and other [[fairy chess]] problems.

Natch is a command line utility, but there is a [[Java (programming language)|Java]] based graphical interface. iNatch also provides moves with fairy conditions: [[Monochromatic chess|monochrome chess]], Einstein chess, vertical cylinder.
