Economic Observer Network Exclusive Report on the 29th: According to Sina Technology, Doubao is advancing product planning in the direction of personal assistants. An informed source stated that, continuing last year's strategy for the Doubao Mobile Assistant in the personal agent direction, Doubao had already begun internal testing of exploratory products for personal assistants in April this year.
The source revealed that the exploratory project was then codenamed "Spell" and was primarily led by the Doubao Mobile Assistant team. However, due to reasons such as the launch of the Doubao phone, it had not been officially released to the public.
The source indicated that after personal assistant products like Muse and Instinct gained attention overseas, Doubao has also accelerated the external release of its personal agent capabilities. The plan is to more deeply integrate the previous Spell project with Doubao products. The new product will be jointly responsible by the Spell project team and the Doubao conversational team, and is expected to be launched to the public soon.
In December 2025, the technical preview version of the Doubao Mobile Assistant made its debut, first equipped on the Nubia M153 engineering sample developed in collaboration with ZTE. In September 2026, the consumer version of the Doubao Mobile Assistant was officially released, landing on the Nubia NaviX Ultra model, which emphasized daily usability and stability more than the preview version. Spell can be seen as an extension of Doubao's personal agent capabilities accumulated on the mobile end into an independent application form.
