  The Cadmium Zinc Telluride Imager on AstroSat has proven to be a very
effective all-sky monitor in the hard X-ray regime, detecting over three
hundred GRBs and putting highly competitive upper limits on X-ray emissions
from gravitational wave sources and fast radio bursts. We present the
algorithms used for searching for such transient sources in CZTI data, and for
calculating upper limits in case of non-detections. We introduce CIFT: the CZTI
Interface for Fast Transients, a framework used to streamline these processes.
We present details of 88 new GRBs detected by this framework that were
previously not detected in CZTI.
