Microsoft has introduced its first-ever computer use agent, Magentic-UI, at the Build 2025 developer conference. Described as a “human-centred web agent”, the new interface is designed to collaborate with users in performing complex online tasks while maintaining full transparency of its actions.
Unlike traditional AI agents, Magentic-UI operates with the user at the centre of its processes. It enables real-time project collaboration, giving users the ability to modify plans, pause execution, provide feedback in natural language, or even resume direct control. A key feature of this system is its visible task panel, which shows all agent actions step-by-step—aiming to build user trust and promote transparency.
Microsoft is positioning Magentic-UI as part of its broader vision of agentic computing, similar in function to tools such as OpenAI’s Operator or Anthropic’s Computer Use. The platform supports web browsing, code execution in Python and shell environments, and file analysis. It is capable of performing tasks such as making restaurant reservations or completing online purchases—all while asking for explicit user consent before executing any irreversible action, like placing an order or adding items to a shopping cart.
The system’s architecture is built on Magentic-One, Microsoft’s proprietary agentic framework, and consists of four distinct AI agents working in unison:
