Īlthough the first channel to use a CG avatar for vlogging purposes on YouTube was the channel of English-Japanese Ami Yamato, who debuted her first video in 2011, Kizuna is the world's first virtual YouTuber with the characteristics as we know today, much like the one who coined the term Virtual YouTuber. After a live concert held on 24 February 2022, she went on indefinite hiatus. A second channel, "A.I.Games", was opened in March 2017 for gaming content, and a third, "A.I.Channel China", opened in June 2019 for a Chinese audience.

Kizuna AI posted her first YouTube video on her "A.I.Channel" on 29 November 2016.

From her debut in 2016 until 2021, she was the most subscribed VTuber on YouTube, with more than 4 million subscribers across three YouTube channels, 1 million subscribers on Chinese video platform Bilibili. Kizuna AI ( Japanese: キズナアイ, Hepburn: Kizuna Ai ) is a Japanese virtual YouTuber (VTuber) currently part of Kizuna AI Inc., a subsidiary of digital entertainment company Activ8.
