PIRCH or pIRCh is a shareware Internet Relay Chat (IRC) client published by Northwest Computer Services. Its name is an acronym – PolarGeeks IRC Hack. The last version of the program, known as PIRCH98, was released in 1998. PIRCH has in the past been considered to be the number-two Windows IRC client behind mIRC. PIRCH inspired the creation of Vortec IRC due to a lack of software updates.
