Chinese startup StepFun has decided to approach the smartphone as a ‘pocket agent’ and on July 13, 2026, presented the StepX Neo — a phone where the main character is AI, not a list of applications.
A phone with an agent instead of a menu
StepX Neo runs on its own Step AOS system. Inside it lives the Amoo agent — not just an assistant, but a ‘task executor’. You give it a normal command:
- ‘book a trip for tomorrow’
- ‘pay utility bills and remind me about the receipt’
and then it independently navigates through applications, uses system functions, employs web services, and brings the task to completion. That is, instead of jumping around the screen yourself, you simply formulate the goal.
Betting on offline intelligence
StepFun was founded in 2023 by former Microsoft employees, and they are clearly tired of being constantly tied to the cloud. Therefore, in StepX Neo, part of the intelligence works directly on the device itself: the Step Edge model can process requests offline.
This means that:
- the agent doesn’t turn into a ‘dummy’ if the internet is lost;
- there is less dependence on delays and servers;
- your actions at least partially remain within the phone, rather than immediately flying off to remote machines.
The Amoo agent takes on daily routines — trips, payments, reminders, and small tasks — and independently coordinates various services so that you have to intervene as little as possible.
What has been shown and what's next
At the presentation, StepFun demonstrated three key things:
- live real-time translation;
- automation of task chains;
- tight integration with applications and system functions.
This was more of a first ‘trial run’. A full demonstration for the general public is planned for July 17 in Shanghai, at the World Artificial Intelligence Conference. For now, the StepX Neo cannot be bought — neither the initial Chinese sales start nor, especially, a global release have been announced.
Hardware — still behind the scenes
Interestingly, little is known about the ‘hardware’ phone itself:
- the processor, screen, cameras, and memory capacity have not been officially disclosed;
- in rare mentions, a battery in the range of 6000–8000 mAh appears, but this is unconfirmed and looks like preliminary estimates rather than final figures;
- neither the price nor the start date of sales in China has been announced yet.
Instead, the company has launched a 100-day ecosystem co-development program — essentially, a period when they, along with partners and early users, will refine the agent's operating scenarios and integrations.
How it differs from regular smartphones
The main feature of the StepX Neo is not ‘just another assistant’.
Traditional smartphones offer you an assistant who answers questions and at most performs a couple of actions. Here, everything is different:
- the agent is initially conceived as the center of interaction;
- its task is not just to answer, but to complete the entire chain of actions from command to result.
On Android and iOS, similar things often run into ecosystem limitations or the need to constantly go to the cloud. StepX Neo attempts to make the agent-based approach fundamental: the phone as a task executor, rather than a collection of separate applications.
Who is the StepX Neo for, anyway?
This smartphone is not a story for everyone. It is particularly interesting for those who:
- like to try new interface formats;
- are willing to ‘click’ less and formulate tasks more in words;
- are not afraid of giving part of the control to an AI agent.
The key moment will be how Amoo behaves in real-life conditions: when the user has not perfectly calibrated scenarios, but a chaos of chats, deadlines, trips, and payments. If the agent can withstand this real world, the StepX Neo could become the first truly ‘agent-based’ smartphone, rather than just another phone with the fashionable word ‘AI’ on the box.
