Hands-on with ByteDance's Doubao Work: An End-to-End Office Agent Integrated with Lark

智东西 · wechat · 2026-08-27

ByteDance has launched "Doubao Work," an AI Agent product for productivity scenarios that deeply integrates Doubao's multimodal capabilities with Lark's (Feishu) enterprise collaboration ecosystem. A 48-hour hands-on test reveals strong performance in both personal efficiency and organizational collaboration.

Personal Efficiency

Research & Docs: autonomously designs research frameworks, producing 25,000-word reports and 14-page structured PPTs with automated verification and source citations.
Multimodal Dev: orchestrates models to generate text, images, and video, assembling a functional travel planning website with dynamic backgrounds in about 5 minutes.
Interaction: features a side-by-side workspace supporting real-time preview and iterative local editing, similar to Vibe Coding.

Organizational Collaboration

Context Integration: inherits Lark account permissions to access chats, docs, and spreadsheets, enabling cross-source task execution (e.g., automated project weekly reports).
Skill Mechanism: encapsulates capabilities like enterprise search and document I/O into standard skills; supports custom enterprise workflows (e.g., topic scheduling statistics).
Security & Compliance: strictly inherits Lark's permission system, covering device control, encryption, and audit logs.

Computer Use & Extensions

Features visual GUI interaction to perform repetitive tasks like image cropping and form filling like a human user.
Supports persistent cloud desktop tasks and mobile remote control.
Connectors link systems like DingTalk and WeCom, enabling multi-agent team collaboration.
