Monroi was a technology company specializing in electronic chess notation and live game broadcasting. Its flagship product, the Personal Chess Manager (PCM), was a handheld device designed for players to electronically record their moves during FIDE-rated tournaments, replacing traditional paper scoresheets. The system also enabled the live transmission of game data over the internet, making it a pioneering technology in the professional chess world. Founded in the early 2000s, the company aimed to modernize chess tournament coverage but appears to have ceased active operations and support around 2013-2014.
