Overview

Marvis is an AI desktop assistant launched by Tencent in 2026. Unlike most AI products, Marvis isn't a chatbot — it operates at the OS level, controlling system settings, managing files, running local LLMs, and even letting your phone remotely control your PC.

It currently supports Windows, macOS (Apple Silicon), and Android, with iOS expected in mid-June.

Core Features

Local LLM + Privacy Mode

Two running modes:

Efficiency Mode: Cloud-device collaboration, fast and accurate
Privacy Mode: On-device LLM, zero file uploads, maximum privacy protection

Download & Summary

Marvis represents Tencent's bet on the AI desktop assistant category — a space where OS-level integration matters more than chat capabilities. With local LLM privacy mode, it directly addresses data privacy concerns that many AI tools face.
