Tencent Marvis: an OS-level AI steward run by six collaborating agents

Tencent Marvis is an operating-system-level AI assistant from the Tencent App Store team, positioned as an AI steward that understands the person using it. Instead of staying inside a chat box, it reaches into system settings, local files and installed applications, and it delegates the work to six specialised agents so one sentence can turn into a finished task.

Most AI assistants stop at advice. They explain how to clear a full C drive, how to switch off system ads, or how to sort a folder of files, and then leave the clicking to you. Marvis tries to own that second half: task decomposition, file operations, system configuration, app control, information search and web interaction are all covered by its agent set, which shortens the distance between a request and a result.

The six roles are PM (project manager), File Agent, Computer Agent, APP Agent, Search Agent and Browser Agent. When a request arrives, the PM agent breaks the goal into sub-tasks, routes each one to the right specialist and lets them run in parallel — which is why several pieces of work can move at once inside a single conversation.

Two modes sit on top of that structure. Efficiency mode blends on-device responsiveness with cloud compute for broader capability; privacy mode keeps processing local and uploads no files, which matters when the material is a contract, a resume or internal company documents.

What Marvis can do

Multi-agent office work

Six built-in roles cover project management, files, system maintenance, applications, search and browser interaction. The PM agent splits the task and dispatches it, so parallel sub-tasks do not queue behind a single general-purpose assistant.

Deep system control

Change mouse sensitivity, toggle dark mode, read hardware specifications, clean the C drive, generate a battery health report or diagnose a network fault. Actions that used to require digging through several settings panels now start from a plain-language request.

Intelligent file management

Search the contents of local files and images, recognise text inside pictures, build an AI photo library or document library, convert file formats, turn a resume into a web page and review a contract. Search works on what a file contains rather than on its name.

Cross-device remote control

A phone can connect to the computer, watch the running task on screen and take over the controls, with cloud-phone coordination alongside it. Updating a game on the home PC while travelling no longer means walking through a remote desktop.

Visual office view

A dedicated office screen animates what each agent is doing, so it is obvious which one is working, which one is waiting and where an output currently sits.

Two-mode privacy

Efficiency mode combines on-device response with cloud compute; privacy mode processes everything locally with zero file upload. The trade-off is left to the user, decided per task rather than by the product.

How to get started

1. Download the client for your operating system from the official site and install it. No runtime environment has to be assembled first.
2. Pick a mode on first launch: efficiency mode for everyday tasks, privacy mode once sensitive files are involved.
3. Describe the task in natural language — for example updating a game installed on the machine, or removing ads across Windows — and the PM agent decomposes and dispatches it.
4. Open the sidebar on the right of the conversation to inspect the work log, the produced artefacts and a task preview; switch to the office view for a live picture of each agent.
5. When away from the desk, sign in with the same account on a phone to watch the task and issue new instructions.

Who it fits

• Everyday users who would rather not hunt through settings menus for cleanup, diagnostics or configuration changes.
• Knowledge workers with piles of files who need to find an image or document by what is inside it, not by filename.
• People who travel while the main computer stays at home or in the office, and who want remote control without a full remote desktop session.
• Individuals and small teams handling sensitive material, for whom the local-only processing path is the main reason to choose this tool.
• Product and technical people curious about multi-agent coordination, who get a low-cost observation window through the office view.

Limits worth knowing first

• Pricing and payment model: the source lists no price, plan or free quota.
• Supported operating-system versions, hardware requirements and installer size: not disclosed by the source, so check before installing.
• The size of the local model behind privacy mode, and how far its results lag efficiency mode: not disclosed.
• Availability of cloud-phone coordination, how many devices can be online at once, and the concurrent task ceiling: not disclosed.
• System-level permission cuts both ways. Cleaning a disk or rewriting system configuration has a wide blast radius, so back up before letting it touch anything important.
• The published examples — updating a game, blocking system ads — depend on the target software and OS version and will not behave identically everywhere.
• The comparison with OpenClaw and QClaw comes from the source site and is a feature-by-feature reading, not a controlled benchmark.

FAQ

How is Marvis different from a normal AI chatbot?

A chatbot returns advice and text. Marvis agents can act on system settings, files and applications, so the suggestion becomes an executed result. Sitting at the system layer rather than the app layer is the core difference.

What still works in privacy mode?

Privacy mode keeps processing local and uploads nothing, which suits contracts, resumes and internal documents. The source does not publish the exact capability list or performance for that mode, so validate it on a non-critical task first.

What does phone-to-PC control require?

The computer stays signed in, the phone signs in with the same account, and from there the task screen can be viewed and taken over. Specific network or OS-version requirements are not disclosed.

Could it delete files or break system settings by mistake?

It holds high-privilege abilities such as disk cleanup and system configuration changes, so a mistake carries more weight than with an ordinary tool. Back up first and observe its behaviour on low-risk tasks before trusting it with anything critical.
