IA is a Japanese Vocaloid virtual singer developed by 1st Place, whose bright, clear voice has been used in songs, covers and fan projects since her debut in the early 2010s. The phrase IA desu, meaning I am IA, is a self-introduction for a virtual idol, and short clips of it circulate on soundboards and in fan edits as a quick way to identify her without a full song excerpt. Because the line is instantly recognisable to Vocaloid fans and takes less than a second to play, it remains a handy tag for edits, streams and memes centred on IA.
