  Motivated by the coincidence between the Hubble scale during inflation and
the typical see-saw neutrino mass scale, we present a supergravity model where
the inflaton is identified with a linear combination of right-handed sneutrino
fields. The model accommodates an inflaton potential that is flatter than
quadratic chaotic inflation, resulting in a measurable but not yet ruled out
tensor-to-scalar ratio. Small CP-violation in the neutrino mass matrix and
supersymmetry breaking yield an evolution in the complex plane for the
sneutrino fields. This induces a net lepton charge that, via the Affleck-Dine
mechanism, can be the origin of the observed baryon asymmetry of the universe.
