Product Showcase Generator

Generate a marketing website that actually teaches people what a web app does. Not just a hero and feature grid — a multi-page site with real screenshots, animated GIF walkthroughs of workflows, feature deep-dives, and progressive depth from "what is this" to "here's exactly how it works."

Especially valuable for complex apps, agentic AI tools, and anything where a static screenshot doesn't convey the value.

Depth Levels

Default: standard

Browser Tool Detection

Before starting, detect available browser tools:

1. Chrome MCP (mcp__claude-in-chrome__*) — preferred for authenticated apps
2. Playwright MCP (mcp__plugin_playwright_playwright__*) — for public apps
3. playwright-cli — for scripted flows

Workflow

1. Gather Input

2. Capture Screenshots

Use capture-screenshots (shipped in bin/) to capture the app. This is faster and more consistent than generating Playwright scripts each time.

Quick capture (all key pages at once):

capture-screenshots http://localhost:5173 \
  --pages /,/dashboard,/contacts,/settings \
  --output showcase/screenshots \
  --prefix screen \
  --mobile --dark

This produces desktop (1280x720), mobile (375px), and dark mode variants for each page in one run.

For authenticated apps:

capture-screenshots https://app.example.com \
  --pages /,/dashboard,/settings \
  --auth user:password \
  --output showcase/screenshots \
  --mobile --dark

What to capture:

a. First Impression — the main page/dashboard becomes the hero image. Note the immediate value proposition.

b. Features — each major section. Use --pages with all nav paths. Capture 6-10 key screens that tell the product story.

c. "How It Works" flow — the main workflow in sequence. Run capture-screenshots multiple times with --prefix workflow-step as you navigate through the flow steps.

d. Detail shots — zoom into specific UI elements. Use --full-page for scrollable content.

e. Both modes — --dark flag captures light and dark variants automatically. Use the best-looking mode for the hero.

Post-capture optimisation:

img-process batch showcase/screenshots --action optimise --max-width 1920 -o showcase/screenshots-opt

f. Extract the Value Propositions

Don't just list features. For each one, answer: why does the user care?

• BAD: "Contact management page"
• GOOD: "See every client, their history, and what needs attention — in one view"
• BAD: "Search functionality"
• GOOD: "Find anything in seconds — semantic search understands what you mean, not just what you type"

3. Generate the Site

Quick Mode: Single Page (same as before)

One HTML file: hero + feature grid + CTA. Use for MVPs and quick marketing.

Standard Mode: Multi-Page Site

showcase/
├── index.html              # Home — hero, overview, feature highlights, CTA
├── features.html           # All features with screenshots and descriptions
├── how-it-works.html       # Step-by-step workflow walkthrough with screenshots
├── screenshots/            # All captured images
│   ├── hero.png
│   ├── feature-*.png
│   ├── workflow-step-*.png
│   └── *.gif               # Animated walkthroughs
└── styles.css              # Shared styles (or inline Tailwind CDN)

Home page: Hero with animated GIF or key screenshot, 3-4 feature highlights (not all features — just the best), "How It Works" summary (3 steps), CTA.

Features page: Every feature with a real screenshot and benefit-focused description. Group by category if there are 6+. Each feature gets enough space to actually explain what it does.

How It Works page: The primary workflow as a step-by-step visual guide. Each step has a screenshot (or animated GIF), a heading, and 2-3 sentences. This page answers "ok but what does using it actually look like?"

Thorough Mode: Comprehensive Site

showcase/
├── index.html              # Home — hero, overview, value proposition
├── features/
│   ├── index.html          # Feature overview grid
│   ├── [feature-1].html    # Deep-dive: one page per major feature
│   ├── [feature-2].html    # Each with screenshots, GIFs, use cases
│   └── [feature-n].html
├── how-it-works.html       # Full workflow walkthrough
├── use-cases/
│   ├── [use-case-1].html   # Scenario: "A day in the life of..."
│   └── [use-case-2].html   # Scenario: "When a new client calls..."
├── compare.html            # "Why [app] vs alternatives" (optional)
├── screenshots/
│   ├── hero.png
│   ├── feature-*/           # Per-feature screenshot sets
│   └── workflows/           # Animated GIFs
└── styles.css

Per-feature deep-dive pages: Each major feature gets its own page with:

• Hero screenshot of the feature in action
• "What it does" — 1-2 paragraphs explaining the value
• "How it works" — step-by-step with screenshots or GIF
• "Why it matters" — the problem this solves
• Edge cases or power-user tips
• Link to next feature (flow between pages)

Use case pages: Story-driven pages that show the app in a real scenario:

• "It's Monday morning. You open the dashboard and see..."
• Walk through a realistic workflow with screenshots at each step
• Show the outcome — what's different because the user used this app
• These are the most persuasive pages for apps that are hard to explain

Comparison page (optional): "Why [app] vs [alternatives]" — honest comparison, not marketing fluff. Feature table, key differentiators, who it's best for.

4. Animated GIF Walkthroughs

Static screenshots don't convey workflow. For key features, capture animated GIFs that show the actual interaction:

How to capture (using Playwright or Chrome MCP):

1. Navigate to the starting state
2. Start recording screenshots at ~2fps
3. Perform the workflow (click, type, navigate)
4. Stop recording
5. Combine frames into a GIF

Generating the GIF — capture sequential screenshots then combine:

# Capture each step with a sequential prefix
capture-screenshots http://localhost:5173/clients \
  --prefix workflow-01 --output .jez/screenshots
# ... navigate to next state ...
capture-screenshots http://localhost:5173/clients/new \
  --prefix workflow-02 --output .jez/screenshots

# Combine frames into GIF (Python one-liner using Pillow)
python3 -c "
from PIL import Image; import glob
frames = [Image.open(f) for f in sorted(glob.glob('.jez/screenshots/workflow-*.png'))]
frames[0].save('showcase/screenshots/workflows/create-client.gif',
    save_all=True, append_images=frames[1:], duration=500, loop=0)
"

What to animate:

• The primary "create something" flow (2-4 seconds)
• A search/filter interaction (show results appearing)
• A drag-and-drop or reorder operation
• Dark mode toggle (satisfying visual)
• Any "magic moment" where the app does something impressive (AI classification, instant search, real-time update)

GIF guidelines:

• Max 10 seconds / 20 frames — shorter is better
• Capture at 1280x720, display at 640x360 (half size for file size)
• Add a brief pause (3 frames) on the final state so viewers see the result
• Loop continuously — no
