ByteDance, the parent company of TikTok, has built what is currently the most popular AI chatbot in China: Doubao. But ByteDance has been quietly marketing Cici to users in the United Kingdom, Mexico, and several Southeast Asian countries. Thanks to that marketing push, downloads of the Cici app have seen a noticeable increase recently. In Mexico, for example, Cici has been the most downloaded free app on the Google Play Store every day for the past week. In the UK on Thursday, Cici was the ninth-most-popular free app in Apple’s App Store.
