What is Tencent Marvis?

Tencent Marvis is an operating system-level AI assistant launched by Tencent. Its official website describes it as "an AI assistant that knows you better" and "your 24-hour AI housekeeper". The biggest difference between it and common conversational assistants lies in its location—it is not an input box on a web page, but takes over PC files, applications and system settings, and can also use a mobile phone to remotely control the computer. It should be noted that "Tencent Yuanbao" collected on this site is another product, and the two should not be confused.

Who is it for?

People who have local documents, contracts and screenshots scattered across multiple drives and need to find materials by content rather than by file name
Ordinary users who are unfamiliar with computer settings and want to get system cleanup and network repair done with one sentence
Field workers and managers who need to remotely run tasks on their computers via mobile phones and check the execution progress
People who handle sensitive files and cannot use assistants that upload their data to the public cloud
Learners who want to organize books, notes and job-hunting materials into a personal knowledge base

Key features

Intelligent Retrieval of Local Files and Images

The official website states that it integrates multiple local models to understand files, enabling searches of file content, image content, and text within images. It also offers specialized features such as AI photo galleries and AI document libraries based on dimensions like portraits, content themes, festivals, and locations.

Dual-mode Switching

The official offers a "Efficiency Mode" with end-cloud collaboration (described by the official as fast and accurate) and a "Local Mode" that uses on-device large models. The latter promises zero file uploads to protect privacy to the greatest extent.

Set up your PC with a single sentence

The official states that it has an in-depth understanding of PC operating systems and hardware information, allowing you to query PC configurations and modify system settings with just one sentence. Examples listed on the official website include system cleanup and network repair.

Remote control of the computer via mobile phone

The official website states that after connecting the mobile phone to the computer, you can real-time view the task execution screen and take over at any time; tasks that can be completed on the computer can also be done remotely through the mobile phone.

In-depth File Understanding and Generation

It supports the understanding and analysis of various local files such as documents and spreadsheets, covering content optimization, chart generation, copy polishing and format conversion.

One-click invocation of applications

The official website mentions that it supports one-click invocation of APK and EXE applications. The official states that Marvis uses the latest models such as deepseek and Hunyuan.

How to use Tencent Marvis

The official website sets the configuration thresholds: Windows requires a CPU with 4 cores or more, 8GB of RAM or more, a solid-state drive, and Win10 or above x64.
macOS requires Apple Silicon (M1 and above) and macOS 13 or above.
there are also Android and iOS clients available for download via QR code scanning.
If you have average hardware and value privacy, choose Local Mode, but the performance of on-device models is usually inferior to that of the cloud-edge collaboration mode.
if you make "no file uploads" a hard requirement, you have to accept the loss of some capabilities.
Switching to Efficiency Mode allows files to be processed in the cloud.
For company confidential documents and personal ID files, you should first confirm the compliance requirements of your organization.
When remotely controlling your computer with your phone, pay attention to the account security and device binding on the phone side, and be especially cautious about remote sessions on public networks.
The official website provides a User Agreement and Privacy Policy, and the specific scope of data processing shall be subject to the policy.
the official states that it supports the local mode with local large models, and the functions may vary by version, which shall be subject to the actual display on the client.
