ByteDance has been preparing a personal AI agent, provisionally called Spell, since April 2026, with a possible launch in the coming weeks. Inspired by Muse, it is expected to integrate with Doubao, ByteDance’s mobile AI assistant, and move beyond conversation to perform tasks such as booking flights. The company aims for a release before China’s National Day holiday in early October 2026, although no launch date has been confirmed. Muse, launched on September 8, 2026, surpassed 2.5 million downloads in its first two weeks, while Tencent is also developing a similar consumer agent.
