Marvis

Marvis is an operating-system-level AI assistant built by Tencent's app store (Yingyongbao) team, positioned as the user's 'digital butler.' It breaks through the limits of traditional web-based AI, using deep system access and file awareness to let users control their computers and phones through natural language.

Core Capabilities

• System-level control: Directly senses and modifies system settings, cleans junk files, and detects hardware configurations - truly controlling the whole computer with a single sentence.
• Deep file management: Supports semantic, precise search across local documents, images, and invoices, and can auto-archive, extract key information, and generate reports.
• Dual-mode operation: Offers a cloud-plus-device 'efficiency mode' and a purely local 'privacy mode' that works offline with zero file uploads, protecting your core assets.
• '1+5' multi-agent system: One master agent plus 5 specialist agents covering files, apps, search, and more collaborate efficiently on complex tasks.
• App automation execution: GUI awareness lets it operate stock software and third-party applications through natural language, replacing tedious manual clicking.
• Cross-device remote control: View and control your computer desktop in real time from your phone for seamless PC-mobile collaboration.

Use Cases Extremely well suited to office professionals who process and retrieve large volumes of local files daily (finance, legal, research staff), ordinary users who dread fiddly system maintenance, and heavy users who work across both PC and mobile and need multi-device coordination.

Unique Advantages This is currently the closest thing to an 'AI OS' among desktop assistants. Compared with tools like Microsoft Copilot, it offers cross-device control far better tuned to habits in China, and its purely local privacy mode completely removes security concerns about sending valuable data to the cloud.

Editor's Review Marvis breaks the boundary of traditional AI chat tools and genuinely graduates to 'system-level butler.' With install-and-go simplicity, completely free access, and irreplaceable local file processing, it is an excellent choice for Windows and Mac users looking to boost office productivity.
