Why Doubao Phone Assistant Went Viral
In late 2025, ByteDance and ZTE launched the Doubao Phone Assistant: a phone with built-in AI that operates apps when you speak—price comparison, bulk job applications, video browsing, and more. Priced at ¥3,499, it sold out on launch day; resale prices briefly exceeded ¥5,000.
Its success proved one thing: AI phone control is real demand. Many people will pay for "say a word and someone taps the screen for me." But it also reveals a barrier: an all-in-one hardware device costs money and locks you to that device.
Three Tiers of Alternatives
If you don't want to buy a ¥3,499 device just for AI phone control, there are roughly three paths:
| Approach | Examples | Best for | Barrier |
|---|---|---|---|
| Open-source frameworks | Open-AutoGLM, Mobile-Agent, Droidrun | Developers willing to self-host | High (code, environment setup) |
| On-device AI apps | OEM-built AI assistants | Individuals, one phone | Low, but limited by the app |
| Free commercial software | iDeviceFarm | Studios managing many phones | Low—install on PC and go |
Open-Source Frameworks: Free but Labor-Intensive
Open-AutoGLM, Mobile-Agent, and Droidrun are open-source projects with a similar idea: screenshot the screen, let the model decide where to tap. Fully free and customizable—but high technical overhead: Python environments, model API keys, compatibility issues. Great for tinkerers; less friendly for business teams.
Free Commercial: The iDeviceFarm Approach
iDeviceFarm takes a different path: no hardware sales, software completely free, runs on your own computer. Android, iOS, and HarmonyOS phones you already own plug in as AI-controllable devices—no extra purchase required.
- Free: No paywalls, no signup, no waiting for sales;
- Use your own phones: Existing devices connect directly, many managed in one place;
- Local runtime: Data stays on your PC, no server needed;
- MCP integration: Connect to WorkBuddy, Claude, and other AI assistants to drive phones.
How to Choose
- Want convenience, budget OK: Doubao Phone Assistant remains a complete hardware experience;
- Developer, enjoy tinkering: Open-source frameworks offer freedom at the cost of time;
- Have phones already, try free first: Start with iDeviceFarm—run your first device immediately, scale when it proves useful.
Bottom line: Doubao proved AI phone control is worth using; free options make that capability accessible to everyone. Try a phone you already have—it beats debating specs.
