# AI Validation

> Assert text, states, and counts. Works standalone or after extraction.

## When to use

Use Validation to verify content and UI state. Validation can work without prior extraction, or validate fields extracted earlier.

## Numeric values use {{value}}

Numbers in schemas use double‑brace formatting: `{{10}}`.

## Examples

Standalone:

```text theme={null}
validate that page title is Login
```

After extraction (matching field names):

```text theme={null}
validate that appleCount equals {{40}}
```
