Computer-Using Agent (CUA)

What Is a Computer-Using Agent?

For SEO and marketing, computer-using agents open up new automation possibilities: they can perform audits, analyze competitors, or consolidate data from various tools without needing APIs. Unlike classic bots, CUAs understand the visual context of an application and navigate independently through complex workflows.

What Is a Computer-Using Agent?

A computer-using agent (CUA) is an AI that can directly operate graphical user interfaces — through screen recognition, mouse clicks, and keyboard input, just as a human would. This enables the automation of software that offers no API interface. The agent sees the screen content as a screenshot and interacts autonomously with buttons and input fields.

A computer-using agent (CUA) is an AI that does not work through APIs or command lines but directly operates graphical user interfaces (GUIs) — the way a human would. The agent sees the screen content as a screenshot, recognizes buttons, input fields, and menus, and performs mouse clicks and keyboard inputs. This enables the automation of software that provides no API interface.

The technology is based on multimodal models that can visually understand screen content. The CUA first creates a plan for the desired action, then identifies the relevant UI elements on the screen, and executes the necessary interactions step by step. Examples include Anthropic’s Computer Use, OpenAI’s Operator, and Google’s Project Mariner. Unlike Tool Calling, where an LLM generates structured API calls, a CUA works at the visual level.

For businesses, CUAs open up the possibility of automating legacy software that lacks modern interfaces. At the same time, they require strict Guardrails: an agent that can operate arbitrary programs must be clearly constrained. Agentic Engineering provides the methods for safely and reliably integrating CUAs into business processes.
