  The program AutoEFT is described. It allows one to generate Effective Field
Theories (EFTs) from a given set of fields and symmetries. Allowed fields
include scalars, spinors, gauge bosons, and gravitons. The symmetries can be
local or global Lie groups based on U(1) and SU(N). The mass dimension of the
EFT is limited only by the available computing resources. The operators are
stored in a compact, human and machine-readable format. Aside from the program
itself, we provide input files for EFTs based on the Standard Model and a
number of its extensions. These include additional particles and symmetries,
EFTs with minimal flavor violation, and gravitons.
