## 🌟 **What is jpglens?**

**jpglens** is a revolutionary AI-powered testing tool that analyzes your user interfaces through the **context of real user journeys**. Unlike traditional testing tools that check functionality, jpglens understands **user experience, accessibility, and visual design** using advanced AI models.

### 🎯 **The Problem We Solved**

Traditional UI testing tools can tell you if a button *works*, but they can't tell you if it's **intuitive**, **accessible**, or **delightful** to use. jpglens bridges this gap by:

- 🧠 **Understanding Context** - Analyzes components within complete user workflows
- 👁️ **Seeing Like Users** - Evaluates visual design, accessibility, and usability  
- 🚀 **Universal Integration** - Works with your existing testing tools
- 📊 **Actionable Insights** - Provides specific recommendations for improvement

---


## 🏆 **Why We Built This**

> *"After building jpgos design system for millions of users, we realized that traditional testing wasn't enough. We needed a way to ensure our components weren't just functional, but truly **user-centered**. jpglens was born from this need - to test not just if something works, but if it works **beautifully** for real humans."*
> 
> **— Taha Bahrami (Kaito)**, *Creator of jpgos & jpglens*

### 📈 **Our Journey**

1. **The Challenge** - jpgos serves millions of users daily, but traditional testing couldn't catch UX issues
2. **The Experiment** - We integrated AI analysis into our testing workflow  
3. **The Breakthrough** - AI could identify usability issues that humans missed
4. **The Solution** - jpglens was born, making this power available to everyone

*Special thanks to **Ashkan** for his invaluable support and guidance throughout this journey.*

## ⚡ **Quick Start**

### Installation

```bash
# Install jpglens
npm install --save-dev jpglens

# Install your preferred testing framework
npm install --save-dev @playwright/test
# or
npm install --save-dev cypress  
# or  
npm install --save-dev selenium-webdriver

export JPGLENS_API_KEY="your-api-key-here"
export JPGLENS_MODEL="openai/gpt-4-vision-preview"

# Optional: Set custom base URL for Azure OpenAI, local servers, or proxies otherwise it works with https://api.openai.com
export JPGLENS_BASE_URL="https://my-resource.openai.azure.com/v1"
```

### 🎭 **Playwright Integration**

```javascript
// tests/ai-visual.spec.js
import { test } from '@playwright/test';
import { analyzeUserJourney } from 'jpglens/playwright';

test.describe('E-commerce Purchase Flow', () => {
  test('user can complete purchase', async ({ page }) => {
    await page.goto('/product/123');
    
    // Standard Playwright actions
    await page.click('[data-testid="add-to-cart"]');
    await page.fill('[data-testid="quantity"]', '2');
    
    // 🔍 AI Analysis - Understands user context
    await analyzeUserJourney(page, {
      stage: 'product-selection',
      userIntent: 'add item to cart',
      context: 'e-commerce purchase decision',
      criticalElements: ['add-to-cart button', 'price display', 'stock status']
    });
    
    await page.click('[data-testid="checkout"]');
    
    // 🔍 AI Analysis - Checkout flow
    await analyzeUserJourney(page, {
      stage: 'checkout-initiation', 
      userIntent: 'complete purchase',
      context: 'high-intent purchase flow',
      criticalElements: ['form fields', 'payment options', 'security indicators']
    });
  });
});
```

### 🌲 **Cypress Integration**

```javascript
// cypress/e2e/user-journey.cy.js
import 'jpglens/cypress';

describe('Dashboard User Flow', () => {
  it('user analyzes business metrics', () => {
    cy.visit('/dashboard');
    cy.get('[data-cy="date-filter"]').select('last-30-days');
    
    // 🔍 AI Analysis with Cypress
    cy.analyzeUserExperience({
      journey: 'data-analysis-workflow',
      userType: 'business-analyst', 
      expectation: 'quickly understand key metrics',
      context: 'daily business review meeting preparation'
    });
  });
});
```

### 📖 **Storybook Integration**

```javascript
// Button.stories.js
import { analyzeComponentStates } from 'jpglens/storybook';

export const InteractiveStates = {
  args: { variant: 'primary' },
  play: async ({ canvasElement }) => {
    const canvas = within(canvasElement);
    const button = canvas.getByRole('button');
    
    // Test different states
    await userEvent.hover(button);
    await userEvent.focus(button);
    
    // 🔍 AI Analysis of component states
    await analyzeComponentStates(canvas, {
      component: 'Primary Button',
      states: ['default', 'hover', 'focus', 'active'],
      context: 'critical call-to-action in checkout flow',
      designSystem: 'jpgos'
    });
  }
};
```

---


## 🎯 **Core Features**

### 🧠 **Contextual Intelligence**
jpglens doesn't just see components - it understands **user context**:

```javascript
// Context-aware analysis
await analyzeUserJourney(page, {
  userType: 'first-time-visitor',     // Affects expectations
  deviceContext: 'mobile-on-the-go',  // Affects interaction patterns  
  urgency: 'high',                    // Affects tolerance for friction
  expertise: 'novice',                // Affects need for guidance
  businessContext: 'e-commerce-conversion' // Affects success metrics
});
```

## 📈 **Reporting & Analytics**

### 📊 **Rich Visual Reports**

jpglens generates comprehensive reports with:

- 📸 **Screenshot Analysis** - Visual annotations and recommendations
- 📈 **Trend Tracking** - UX quality over time
- 🎯 **Actionable Insights** - Specific code changes and design recommendations  
- 📱 **Multi-Device Views** - Analysis across different screen sizes
- ♿ **Accessibility Scores** - WCAG compliance tracking

### 🔍 **Sample Report Output**

```markdown
# 🔍 jpglens Analysis Report

## 📊 Overall UX Score: 8.2/10

### 🎯 Key Findings

**✅ Strengths:**
- Clear visual hierarchy guides user attention effectively
- Consistent design system implementation
- Strong accessibility compliance (WCAG 2.1 AA)

**⚠️ Areas for Improvement:**
- Mobile touch targets below 44px minimum (checkout button)
- Form error messages appear after 3s delay - too slow for user context
- Color contrast ratio 3.8:1 on secondary buttons (needs 4.5:1)

### 🛠️ Specific Recommendations

1. **Checkout Button (Mobile)**
   ```css
   .checkout-btn {
     min-height: 44px; /* Current: 38px */
     min-width: 44px;
   }
   ```

2. **Form Validation**
   ```javascript
   // Show errors immediately on blur, not on submit
   onBlur={() => validateField(fieldName)}
   ```

3. **Color Contrast**
   ```css
   .btn-secondary {
     background-color: #5a6c7d; /* Current: #8a9ba8 */
   }
   ```
```

<!-- BEGIN: MCP SECTION -->
## Use with Model Context Protocol (MCP)

Let AI agents (Cursor/Claude/OpenAI) run jpglens analyses via an MCP server.

### Quickstart
1. Build:
```bash
# Install MCP server
npm install -g jpglens-mcp-server

# Or build from source
pnpm -F jpglens-mcp-server build
```
2. Cursor → Settings → Features → MCP → **Add**
- Type: `stdio`
- Command: `npx jpglens-mcp-server` (if installed globally)
- Or: `/ABS/PATH/TO/repo/packages/mcp-server/dist/index.js` (from source)

**SSE (optional):**
Run `PORT=3333 npx jpglens-mcp-server-sse` and point hosted agents to `http://localhost:3333`.

### Advanced
- Retries/backoff in batch runs
- Reporters: JSONL, S3 (set `JPGLENS_REPORTER=both` to enable both)
- Normalized `structuredIssues` for auto-fix agents
<!-- END: MCP SECTION -->
