WebWhat is HoTT? Homotopy Type Theory is an extension of Martin-Lof's intensional type theory. Martin-Lof is a fairly vanilla flavor of dependent type theory which is able to "talk about" pi types, sigma types, the natural numbers, identity types and equality, and can be extended with inductive and coinductive types.
