User defined class in helper

Hi, I defined my own class in a helper, but the class does not seem to be available in my view. I am assuming that only the helpers methods are available in my view. really what I should do is make the class available to the controller, and initialize my class from there, but I would still like access to the class for its class methods So my question is: where should I put the class?

well I figured something out, I made the class a model.
