  We propose a large class of supergravity models in terms of a single chiral
matter superfield, leading to (almost) arbitrary single-field inflationary
scalar potentials similar to the F-term in rigid supersymmetry. Those scalar
potentials are positively semi-definite (in our approximation), and can
preserve supersymmetry at the end of inflation. The only scalar superpartner of
inflaton is stabilized by a higher-dimensional term in the Kahler potential. We
argue that couplings of the inflaton to other sectors of the particle spectrum
do not affect the inflationary dynamics, and briefly discuss reheating of the
universe by the inflaton decays.
