Character.AI is a popular AI platform that revolutionizes the way we communicate with AI by crafting text responses that mimic human conversation. Since its beta version was unveiled in September 2022, the platform has seen a meteoric rise in popularity due to its unique proposition of enabling users to craft a fully-customizable AI companion with distinct personality traits and values. Character.AI was conceived in 2021 by AI and large language model visionaries Noam Shazeer and Daniel De Freitas. The platform has seen exponential growth since its beta launch, with nearly 100 million monthly site visits and over two billion user messages sent since its inception. Character.AI has raised a total of $150 million in a Series A funding round led by Andreessen Horowitz (a16z).
