📦 Ollama LLaVA Integration - Complete Deliverables

✅ Implementation Summary

Feature: Local AI Vision Support for Screenshot Intelligence
Technology: Ollama + LLaVA 7B
Status: ✅ Production Ready
Date: January 15, 2026

---

📋 Deliverables Checklist

1. Backend API Route File ✅

File: backend-copy/routes/screenshotIntelligence.js

Key Functions:

// Analyze image with Ollama LLaVA
async function analyzeWithOllama(imageUrl, systemPrompt, userPrompt)

// Analyze image with OpenAI GPT-4o
async function analyzeWithOpenAI(imageUrl, systemPrompt, userPrompt)

Endpoints Updated:

• POST /api/brand-intelligence/screenshots/analyze?provider=ollama|openai

  • Supports both Ollama and OpenAI
  • Auto-detects provider if not specified
  • Returns structured ad data JSON

• POST /api/brand-intelligence/screenshots/generate-hooks?provider=ollama|openai

  • Generates 10-15 creative hooks
  • Marketing angles and reel openers
  • Works with both providers

Provider Selection Logic:

const provider = req.query.provider || req.body.provider || (openai ? 'openai' : 'ollama');

if (provider === 'openai') {
  aiResponse = await analyzeWithOpenAI(imageUrl, systemPrompt, userPrompt);
} else {
  aiResponse = await analyzeWithOllama(imageUrl, systemPrompt, userPrompt);
}

---

2. Utility Function: extractJsonFromModelOutput() ✅

File: backend-copy/utils/jsonExtractor.js

Function Signature:

/**
 * Extract JSON from model output (handles markdown, explanations, etc.)
 * @param {string} text - Raw AI model response
 * @returns {Array|Object} Parsed JSON
 * @throws {Error} If no valid JSON found
 */
function extractJsonFromModelOutput(text)

Extraction Strategies (5 fallback methods):

1. Direct JSON.parse() - Try parsing raw text
2. Markdown code blocks - Extract from ```json ... ```
3. Bracket matching - Find first [{ and last }]
4. Line-by-line parsing - Track brace count for nested JSON
5. Label patterns - Match "here is the JSON:" prefixes

Example Usage:

const { extractJsonFromModelOutput } = require('../utils/jsonExtractor');

const rawResponse = await ollamaAPI.generate(...);
const extractedData = extractJsonFromModelOutput(rawResponse.data.response);
// Returns: [{ brand_name: "Nike", status: "Active", ... }]

Safe Wrapper:

function safeExtractJson(text, defaultValue = [])
// Returns parsed JSON or defaultValue on error (no throw)

---

3. UI Updates: Provider Dropdown + Results Cards ✅

File: src/pages/admin/BrandIntelligenceEnhanced.jsx

State Management:

const [aiProvider, setAiProvider] = useState('ollama'); // 'openai' | 'ollama'

Provider Toggle UI (Lines 1086-1109):

<div className={styles.providerSelection}>
  <label>Choose AI Provider:</label>
  <div className={styles.providerButtons}>
    <button
      className={`${styles.providerBtn} ${aiProvider === 'ollama' ? styles.providerBtnActive : ''}`}
      onClick={() => setAiProvider('ollama')}
    >
      <span className={styles.providerIcon}>🏠</span>
      <div className={styles.providerInfo}>
        <span className={styles.providerName}>Ollama (Local)</span>
        <span className={styles.providerTag}>FREE • LLaVA 7B</span>
      </div>
    </button>
    
    <button
      className={`${styles.providerBtn} ${aiProvider === 'openai' ? styles.providerBtnActive : ''}`}
      onClick={() => setAiProvider('openai')}
    >
      <span className={styles.providerIcon}>☁️</span>
      <div className={styles.providerInfo}>
        <span className={styles.providerName}>OpenAI (Cloud)</span>
        <span className={styles.providerTag}>PAID • GPT-4o Vision</span>
      </div>
    </button>
  </div>
</div>

API Integration:

// In handleAnalyzeScreenshots()
const response = await axios.post(
  `${API_URL}/api/brand-intelligence/screenshots/analyze?provider=${aiProvider}`,
  formData,
  { headers: { Authorization: `Bearer ${token}` } }
);

// In handleGenerateHooks()
const response = await axios.post(
  `${API_URL}/api/brand-intelligence/screenshots/generate-hooks?provider=${aiProvider}`,
  { ads: extractedAds },
  { headers: { Authorization: `Bearer ${token}` } }
);

Results Display:

• Extracted ads grouped by launch month
• Ad cards show: brand, status, dates, platforms, CTA, copy, format
• Hook cards show: hook text, angle, reel opener
• Copy buttons for individual hooks or bulk copy

CSS File: src/pages/admin/BrandIntelligence.module.css

New Styles Added (Lines 1700-1778):

.providerSelection { margin-bottom: 30px; }
.providerButtons { display: grid; grid-template-columns: 1fr 1fr; gap: 15px; }
.providerBtn { /* Flex layout with icon + info */ }
.providerBtnActive { /* Blue gradient, elevated shadow */ }
.providerIcon { font-size: 32px; }
.providerInfo { display: flex; flex-direction: column; }
.providerName { font-weight: 600; color: #2d3748; }
.providerTag { font-size: 11px; text-transform: uppercase; }

5. Error Handling and Logging ✅

Backend Error Handling:

Provider Validation:

if (provider === 'openai' && !openai) {
  return res.status(503).json({
    success: false,
    message: 'OpenAI provider selected but API key not configured. Use Ollama instead.'
  });
}

Ollama Connection Errors:

try {
  const response = await axios.post(`${OLLAMA_BASE_URL}/api/generate`, ...);
} catch (error) {
  console.error('[Ollama] Error:', error.message);
  throw new Error(`Ollama analysis failed: ${error.message}`);
}

JSON Extraction Errors:

try {
  const extractedData = extractJsonFromModelOutput(aiResponse);
} catch (parseError) {
  console.error('[AI Vision] JSON parse error:', parseError.message);
  // Continue processing other images instead of failing entire batch
}

Cloudinary Upload Errors:

cloudinary.uploader.upload_stream(
  { folder: 'aurax-ad-screenshots' },
  (error, result) => {
    if (error) {
      console.error('[Cloudinary] Upload error:', error);
      reject(error);
    } else {
      resolve(result.secure_url);
    }
  }
);

Comprehensive Logging:

console.log('[Screenshot Intelligence] Starting analysis...');
console.log(`[Screenshot Intelligence] Provider: ${provider}`);
console.log(`[Screenshot Intelligence] Received ${req.files.length} files`);

console.log('[Cloudinary] Upload success:', imageUrl);
console.log('[AI Vision] Analyzing image 1/10 with OLLAMA...');
console.log('[AI Vision] Raw response:', rawResponse.substring(0, 200));
console.log('[AI Vision] Extracted 3 ads from image 1');

console.log('[Screenshot Intelligence] Total ads extracted: 15');

Frontend Error Handling:

try {
  const response = await axios.post(...);
  if (response.data.success) {
    setExtractedAds(response.data.ads);
  }
} catch (err) {
  console.error('Screenshot analysis error:', err);
  const errorMsg = err.response?.data?.message || 'Failed to analyze screenshots';
  setAnalysisError(errorMsg);
  alert(errorMsg);
} finally {
  setIsAnalyzing(false);
}

Error Display:

{analysisError && (
  <div className={styles.errorAlert}>
    ⚠️ {analysisError}
  </div>
)}
