The Chern character is a central construction which appears in topology, representation theory and algebraic geometry. In algebraic topology it is for instance used to probe algebraic K-theory which is notoriously hard to compute, in representation theory it takes the form of classical character theory. Recently, Toen and Vezzosi suggested a construction, using derived al-gebraic geometry, which allows to unify the various Chern characters. I will explain what it me-ans to categorify the Chern character. In the categorified picture algebraic K-theory is replaced by the category of non-commutative motives.
