# Overview

> Screen-based automation and extraction with Computer Use tools

Computer Use gives Alter a UI execution layer for desktop workflows. It can inspect windows, interact with UI elements, and pace multi-step flows.

## Tool set

* [Get Active App Context](/apps-tools/computer-use-get-active-app-context)
* [Perform](/apps-tools/computer-use-perform)
* [Wait](/apps-tools/computer-use-wait)
* [Scroll](/apps-tools/computer-use-scroll)

## Typical flow

1. Read current UI state with **Get Active App Context**.
2. Trigger UI actions with **Perform**.
3. Use **Scroll** when the target element is off-screen.
4. Add **Wait** between steps for loading or state transitions.
