Marvis
Tencent · AI Assistant · China AI
Marvis is an OS-level AI assistant from Tencent that turns your computer into something you can talk to instead of click through. Rather than answering questions in a chat window, it searches local files and images, adjusts system settings, opens apps, runs web tasks, and controls your PC from your phone after you grant permission. It runs on Windows, macOS, Android, and iOS, and it's free to use with a daily token allowance.
About Marvis
What Is Marvis
Marvis is a desktop and mobile AI agent built by Tencent's App Store team. The name nods to Jarvis, and the pitch is simple: you describe a goal in plain language, and Marvis figures out the steps, picks the right agent, and carries them out on your machine. It sits above your operating system rather than replacing it, so it works with the files, apps, and settings you already have.
The idea is that most computer chores require you to know where things live. Closing startup apps means digging through Task Manager. Cleaning a full drive means guessing which folders are safe to delete. What if you could just say what you want instead? That's the shift Marvis is after. You describe the goal, it reads the relevant system and file data, proposes a plan, and waits for your go-ahead before doing anything risky.
That confirmation step matters. Deleting files, changing core settings, or touching payments all trigger a hard check, so you stay in control. Marvis also ships an offline privacy mode that keeps file parsing, image recognition, and chats entirely on your device. The catch: the privacy mode leans on a local model, so it needs a reasonably strong PC, and some of the more complex planning still works best in the default efficiency mode.
Getting Started
- Go to the official site at marvis.qq.com and download the build for your system (Windows, macOS, or mobile).
- Log in by scanning with WeChat or QQ. No invite code is needed.
- Grant the permissions Marvis requests, such as file indexing and, on mobile, the accessibility service that lets it operate apps.
- Open the chat box and describe a task in plain language, such as asking which startup programs slow down your boot.
- Review the execution plan, confirm the sensitive steps, and let Marvis carry out the rest.

Key features
A Team of Six Built-In Agents
Marvis ships with a set of specialist agents rather than one general model. A main agent takes your request, breaks it down, and routes each part to a File, Computer, App, Browser, or Search agent. You don't configure workflows or install skills to get started; the agents are ready out of the box.
Natural-Language System Control
You can ask about hardware specs, battery health, or network status, and adjust settings the same way. Marvis reads your machine's actual state, explains the cause of a problem, and proposes a fix. Launch items, drive cleanup, and Windows ad suppression all run from a single line of text.
Content-Aware File and Image Search
The search goes deeper than filenames. Marvis works as a file search AI for your own machine: it parses document contents, reads text inside images, and sorts files by topic, person, or place. It can build a personal library from your own documents and photos, which solves the "I remember what's in it but not what it's called" problem.
Cross-Device Remote Control
Install the mobile app and connect it to a PC signed into the same account. From your phone you can see the desktop in real time and operate it, which goes past the usual remote command tools. Android can connect to a Mac, and iOS can connect to Windows.
Two Modes for Privacy and Speed
Efficiency mode uses a mix of on-device and cloud processing for faster responses. Privacy mode runs everything locally, including parsing and image recognition, and keeps working when you're offline. For a finance or legal file, that distinction is the point.
Safety Checkpoints on Risky Actions
Delete, modify, or system-level operations trigger a confirmation prompt with a risk level attached. Payments and similarly sensitive actions stay with you. Agents handle the busywork, but they don't get a free hand on anything irreversible.
Pros and cons
Pros
- Free to use with a generous daily token allowance, so casual and regular use both fit.
- Preloaded agents mean no setup work before your first task.
- Content-level file and image search is more useful than filename matching alone.
- Offline privacy mode keeps sensitive files from leaving your machine.
- Mobile-to-PC control works across Windows, macOS, Android, and iOS.
Cons
- Privacy mode needs a capable PC, and older or low-spec machines may lag.
- Some task automation is still early; scheduled actions are simpler than what power users might expect.
- Handling many agent tasks at once can slow background performance on a modest laptop.
- There's no clear public API, so you can't wire Marvis into your own tooling.
