Ui Demo

This is a methodical three-phase approach to recording demo videos with Playwright that treats "discover, rehearse, record" as a hard workflow. The discovery phase dumps actual DOM elements before you write selectors, which catches the silent failures that usually ruin recordings (custom dropdowns, contenteditable fields, dynamic forms). Rehearsal verifies every selector with loud failures and element dumps. Recording only happens after both phases pass, using cursor overlays, natural pacing (25-40ms typing delay, 2-4s pauses), and storytelling structure. It's opinionated about never skipping phases and never teleporting the cursor. If you've burned time on recordings that break halfway through because a selector was wrong, this catches it earlier.

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.

Phase 1: Discover

Before writing any script, explore the target pages to understand what is actually there.

Why

You cannot script what you have not seen. Fields may be <input> not <textarea>, dropdowns may be custom components not <select>, and comment boxes may support @mentions or #tags. Assumptions break recordings silently.
