# AI computer use: a guide to browsers, desktop apps and real actions

Understand AI computer use and try practical browser testing and desktop workflows, with current OpenAI setup links and observable results.

Beyond the answer box. Into the interface.

An assistant with the right tools can inspect a page, operate a permitted app and verify what changed. Learn when to use a browser, when a direct integration fits better, and how to give a computer-use task a clear finish line.

## Start with your situation

### What is a useful first browser task?

Test a local page with normal, empty and awkward inputs.

### How does it work with desktop apps?

Set up access, name the window and verify the final state.

### What about just reading and editing files?

Understand the difference between file tools and graphical control.

## In the handbook

### Use AI to test a website in the browser: a practical acceptance walkthrough

Test real website behavior with an AI browser agent: search, forms, persistence, mobile layouts, errors and evidence of what actually worked.

### AI computer use in practice: apps, files and a clear finish line

Plan a useful AI computer-use task across desktop apps, understand setup and foreground behavior, and verify the resulting file or app state.
