# Doubao

## Profile
Doubao is [[entity-bytedance]]'s phone / OS-layer agent, designed to interpret **screen context** and execute actions across different apps.

## Role in this source
Doubao is the exemplar of **the OS layer** (design #4 in [[framework-designs-of-delegation]]). Its launch reportedly caused competitors like [[entity-alibaba-d3]] and Tencent to **tighten risk controls** because of cross-app execution conflicts — the concrete trigger for the open question [[question-cross-app-execution-conflicts]].

> Enrichment: canonical entity is **ByteDance's Doubao** AI assistant/model brand, used as a consumer-facing AI layer; the exact OS-layer delegation claims should be checked against primary product documentation.
