# What is Fathom

Fathom is an AI-powered test generation capability within Drizz that enables intent-based test execution and automatic script creation.

Instead of manually authoring test steps, users describe what a test should accomplish in plain language. Fathom interprets that intent, executes the scenario on a connected local emulator, and generates a structured automation script at the end of the run.

**Fathom is designed for:**

1. Rapid test script creation without manual authoring
2. Intent-driven execution on local Android emulators
3. Automatic detection of conditional logic and validations
4. Generating reusable scripts for test plan integration
