Served 1.9B+ queries as the exclusive AI partner of the 2026 CCTV Spring Festival Gala.

ByteDance's consumer AI assistant (chatbot app: iOS/Android/web), launched Aug 2023, running on Volcano Engine (Doubao models). Proprietary closed product. Introduced a paid Pro subscription tier ~May/Jun 2026. Verified live June 2026 (Wikipedia + China-market app trackers).

Adoption

5 medium confidence

5.0

Doubao reached ~330M total users by May 2026 (en.wikipedia.org/wiki/Doubao); China's most popular AI chatbot; ~60M MAU as of Nov 2024 per Wikipedia. China-market app trackers report ~330M users as of May 2026. NOTE (verifier): the 330M figure is cited by Wikipedia as TOTAL users, not a measured MAU; the only Wikipedia-stated MAU is ~60M (Nov 2024). Either way the surface clears >10M. Headline counts are aggregator/Wikipedia-compiled (no single ByteDance primary MAU disclosure), so confidence medium. Volcano Engine reportedly serves ~120T tokens/day.

Capability

3 medium confidence

3.0

Feature-rich consumer assistant with multimodal + emerging agentic e-commerce, but narrow on the ui_api feature axes (single provider, consumer-only). Not a category frontier-definer on capability.
