Marvis

Marvis is Tencent’s next-generation desktop AI assistant designed to operate directly within the Windows operating system — not as a Standalone APP or web interface, but as a deeply integrated layer that transfORMs your entire computer into an Intelligent, responsive workspace. Inspired by the fictional J.A.R.V.I.S., Marvis bridges the gap between natural language commands and low-level system ACTions, enabling users to interact with their machines through dialogue while mAIntaining strong privacy controls and real-time responsiveness.

What it does

Marvis functions as a peRSIstent, always-on AI collaborator that interprets user requests in plain language and executes them across multiple domains: system configuration, file management, application automation, web interaction, and semantic search. Unlike traditional chatbots, it doesn’t rely solely on cloud APIs — instead, it leveRAGes hybrid execution (cloud for complex reasoning, local for sensitive Operations) and deploys six specialized AI Agents out of the box to divIDE labor intelligently.

Key capabilities

• system-level control: Adjust settings, check hardware health, manage startup programs, and clean storage — all via voice or text commands.
• Personal knowledge base: Indexes local documents, images, and screenshots using on-device models; supports content-aware search (e.g., 'find photos of my team meeting last month').
• cross-device visualization: View and rEMOtely control your Windows desktop from a mobile device in real time, with Synchronized session state.
• Dual-mode architecture: Switches seamlessly between Efficiency Mode (cloud-assisted inference + local data processing) and Privacy Mode (100% offline, zero data upload).
• Hard-confirm SECurity: Blocks irreversible actions like file deletion or registry edits until manually approved — with additional safeguards for financial or identity-sensitive tasks.

Who it is for

Marvis targets power users, knowledge workers, developers, and privacy-conscious Professionals who want unified, secure, and intuitive control over their digital environment without sacrificing speed or Data Sovereignty. It’s especially valuable for those manAGIng large local datasets, handling confidential documents, or seeking deeper OS integration than browser-based assistants offer.

How to get started

Visit the official Marvis website to download the Windows CLIent. installation requires administrator privileges to enable deep system access. After setup, users are guided through a brief onboarding flow to activate Agents and configure default preferences. No account creation is mandatory for bASIc use, though syncing across devices requires a Tencent ID.

Pricing and access caveat

Marvis is currently offered free to all users, with a daily allowance of 10 million tokens — sufficient for typical personal Workflows. While the core functionality remains accessible without subscription, certain advanced features or future model upgrades may require tiered access. The tool is Windows-only at launch; macOS or web versions have not been announced. Offline operation is fully supported in Privacy Mode, but some capabilities (e.g., real-time web scraping) may vary depending on network conditions and regional availability.
