# UI Demo Video Recorder
Record polished demo videos of web applications using Playwright's video recording with an injected cursor overlay, natural pacing, and storytelling flow.
## When to Use
- User asks for a "demo video", "screen recording", "walkthrough", or "tutorial"
- User wants to showcase a feature or workflow visually
- User needs a video for documentation, onboarding, or stakeholder presentation
## Three-Phase Process
Every demo goes through three phases: **Discover -> Rehearse -> Record**. Never skip straight to recording.

### How
Navigate to each page in the flow and dump its interactive elements:
```javascript
// Run this for each page in the flow BEFORE writing the demo script
const fields = await page.evaluate(() => {
const els = [];
