KAIHE AIBOX, Tencent's WorkBuddy, and ByteDance's Doubao Work — in 2026, all three internet giants have fully committed to the AI office market. On August 25, 2026, ByteDance officially launched "Doubao Work," completing the three-way battle alongside Tencent's WorkBuddy and Alibaba's Qianwen Office. All three claim the same goal: transforming AI from a chatbot into a digital colleague that gets things done. But as you dig deeper, they solve fundamentally different problems.
This article skips the spec sheet comparisons and goes straight to real use cases.
First, Understand This: They Are Not the Same Product
📖 Glossary
AI Box (also known as Agent Computer / Agent PC), is a dedicated local hardware device that runs AI Agents. Pre-installed with an AI agent management system, plug-and-play, running 24/7. Users can remotely command AI to work via Discord, Slack, Telegram, WhatsApp, and more.
Doubao Work is natively built into Feishu (Lark). Its core value lies in accessing your accumulated enterprise context directly — chat history, documents, meeting notes, schedules — without any copy-pasting. The AI naturally knows what project you've been working on all week. If your company uses Feishu, the switching cost is nearly zero.
WorkBuddy is Tencent's desktop-level AI agent. It doesn't bind to Feishu; it binds to your computer itself. It can read and write local files, operate desktop software, execute scheduled tasks, and keep working as long as your computer stays on. KAIHE AIBOX adds a third layer: it doesn't need your computer at all — plug it in and it runs independently 24/7.
Five Dimensions, Head-to-Head
1. Ecosystem Lock-in: Who Can't Survive Without Their Platform
Doubao Work loses half its functionality without Feishu. Its most valuable features — accessing Feishu chat history, meeting context, permission systems — only work within the Feishu ecosystem. If your company doesn't use Feishu, Doubao Work is essentially just another web-based AI chatbot.
WorkBuddy binds to your computer, not a specific IM tool. Its abilities to manipulate local files, execute scheduled tasks, and invoke MCP toolchains work in any environment. KAIHE AIBOX's Hermes scheduled automation doesn't even need a computer — plug it in and the tasks run regardless of any desktop machine's state.
2. Core Capabilities: Who Actually "Does the Work"
Doubao Work's biggest differentiator is its self-developed multimodal models: Seedream 5.0 Pro (image generation) and Seedance 2.5 (video creation). Text, charts, presentations, posters, promotional videos — one platform, no tool-switching required. It also features "Work Partners" — you can assemble a multi-role AI team where different agents collaborate on complex projects.
WorkBuddy excels in three areas: Box Selection Editing (select a paragraph or Excel range and only that area changes), Scheduled Automation ("Every morning at 9, grab industry news. Every Friday at 6, generate a weekly report. Set it once, forget it"), and Knowledge Base Co-writing (local HTML/Markdown files support multi-person, multi-agent collaborative editing with AI suggestions appearing as comments you approve one by one).
KAIHE AIBOX brings the infrastructure layer: when scheduled automation needs to run at 3 AM and your computer is off, KAIHE AIBOX is still there. Its 5W power consumption means it runs continuously without your attention or your electricity bill spiking.
3. Mobile: Who Actually Enables "Remote Working"
Doubao Work supports mobile app remote computer control and cloud computer continuation — even if your physical computer is off, the cloud instance keeps running. On a business trip, you can still fix a document or pull data from your phone.
WorkBuddy's WeChat Direct Connection (launched March 12) lets you send a voice message or text in WeChat, and your office computer's WorkBuddy automatically starts executing tasks. Everything runs locally with privacy guaranteed. Mobile currently mainly handles "sending commands + viewing results" — full operations still require returning to the computer.
KAIHE AIBOX combines the best of both: your WeChat controls the Hermes agent on KAIHE AIBOX, and the result arrives on your phone. No cloud dependency, no computer required.
4. Batch Tasks: Who Handles High-Frequency Repetitive Work
This is where the gap is most obvious.
WorkBuddy handles batch file processing — 7,000 documents classified and renamed uniformly in 30 minutes. Scheduled tasks support automation queues, letting AI run data processing at 3 AM, so you arrive at the office to find results ready. Set up an automation flow once, and it runs 24/7 unattended.
Doubao Work's batch processing is limited by Feishu ecosystem constraints, with file upload size limits and lower per-task throughput. But Doubao's multimodal capabilities are stronger — generating both presentations and videos in one task requires no plugin chains like WorkBuddy does.
KAIHE AIBOX's Hermes framework runs these automations on dedicated hardware with only 5W power draw — no computer fan noise, no electricity concerns about leaving your desktop on overnight.
5. Decision Guide: Who's Right for You
Heavily using Feishu with years of accumulated documents and chat history → Doubao Work. AI naturally knows your context, lowest switching cost, strongest multimodal creation.
Processing large volumes of local files, heavy batch tasks, scheduled automation needs, cross-platform work (not on Feishu) → WorkBuddy. Local file operations and batch processing capabilities are things Doubao Work cannot match.
Want AI running when you're not operating, tasks continuing after shutdown, no cloud dependency, truly 24/7 → KAIHE AIBOX. Its Hermes scheduled automation provides the infrastructure layer that neither cloud product can match when your computer is off.
Their Shared Weakness: Your Computer Has to Stay On
Both Doubao Work and WorkBuddy share one fundamental prerequisite: your computer must stay powered on.
Doubao Work's cloud computer feature can continue running after shutdown, but relies on ByteDance's cloud infrastructure at additional cost. WorkBuddy's scheduled automation depends on your computer staying online — sleep mode or disconnection stops tasks immediately.
KAIHE AIBOX is a plug-and-run AI mini server with only 5W power consumption, built-in Hermes scheduled automation, no dependency on computer power state, no reliance on cloud compute budgets. It doesn't compete with either product — it complements them by handling the 24/7 baseline that neither cloud product can guarantee without your computer running.
