Let X be a space with free loop space LX and let R denote the mod two cohomology of X. We construct a functor of R together with a natural algebra homomorphism into the mod two cohomology of the circle homotopy orbits of LX. When X is 1-connected and R is a symmetric algebra, we show that this is an isomorphism.
