  \emph{TxGraffiti} is a machine learning and heuristic based artificial
intelligence designed to automate the task of conjecturing in mathematics.
Since its inception, TxGraffiti has generated many surprising conjectures
leading to publication in respectable mathematical journals. In this paper we
outline the machine learning and heuristic techniques implemented by
TxGraffiti. We also recall its contributions to the mathematical literature and
announce a new online version of the program available for anyone curious to
explore conjectures in graph theory.
