ByteDance's Douyin has officially named its AI personal assistant project Xiaodu, formerly codenamed Spell, and plans to launch it as an independent app. Currently in intensive internal testing, the final public version will be adjusted based on test results, though no exact release date has been announced. This move extends Douyin's mobile assistant capabilities, previously seen on Nubia devices, into a standalone application. Industry insiders note this allows users to access comprehensive AI services without being restricted by specific phone manufacturers or system integrations, marking a significant milestone in Douyin's AI development.
