OpenAI's artificial intelligence chatbot ChatGPT is the fastest-growing app in history.

This is according to a UBS study (via CBS News, which claims that ChatGPT had 13 million unique visitors per day in January, which is more than double the visitors it had in December. ChatGPT has only been around two months (can you believe it?), and it already has 100 million monthly users, the study concluded.

The study, which cites data from analytics company Similarweb positions ChatGPT well over other fast-growing apps such as TikTok and Instagram. In comparison, it took nine months for TikTok to reach 100 million monthly active users; for Instagram, it took two and a half years.

“In 20 years following the internet space, we cannot recall a faster ramp in a consumer internet app,” USB's analysts wrote in the study.
