Microsoft unveils Magentic-UI, a human-centred AI agent for the web: How it works

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.
