Supported Sites: 20+ job platforms
- LinkedIn, Indeed, Glassdoor
- Greenhouse, Lever, Workday, iCIMS
- SAP SuccessFactors, Taleo, Jobvite
- Databricks, EA Careers, and more
- Generic: Any URL with
/careers/or/jobs/
Detection Logic:
function isJobApplicationPage() {
const url = window.location.href.toLowerCase();
// Check URL patterns
const urlPatterns = [
'linkedin.com/jobs/view',
'indeed.com/viewjob',
'greenhouse.io/jobs',
// ... 20+ more
];
// Must also have job title + (company OR apply button OR requisition)
return hasJobTitle && (hasCompanyInfo || hasApplyButton || hasRequisitionId);
}Accuracy: ~70% (pattern matching alone)
Model: Gemini 2.0 Flash Exp Trigger: Automatic after pattern detection Accuracy: ~90%+ (AI-verified data)
Flow:
- Pattern detection identifies job page
- AI automatically analyzes full page content
- Extracts accurate role, company, confidence
- Compares with pattern data
- Uses AI data if confidence ≥ 50%
Uses DOM selectors:
// Role extraction
const h1 = document.querySelector('h1');
const metaTitle = document.querySelector('meta[property="og:title"]');
const jobTitleClass = document.querySelector('[class*="job-title"]');
// Company extraction
const companyClass = document.querySelector('[class*="company-name"]');
const orgItemprop = document.querySelector('[itemprop="hiringOrganization"]');Issues:
- Breaks when site structure changes
- Extracts abbreviated titles (e.g., "SWE")
- Gets wrong company format (e.g., "Google LLC")
Uses natural language understanding:
const prompt = `Analyze this webpage and extract:
- Job title (full, not abbreviated)
- Company name (simplified, no LLC/Inc.)
- Confidence score (0-100%)`;Benefits:
- Understands context and natural language
- Normalizes data (SWE → Software Engineer)
- Simplifies company names (Google LLC → Google)
- Works on any job site format
Improvements Shown to User:
✓ AI verified and corrected:
Role: SWE → Software Engineer
Company: Google LLC → Google
Tier 1: URL Exact Match (Highest Priority)
// Check if exact same URL already tracked
const urlMatch = await dynamoDB.scan({
FilterExpression: 'JobURL = :url',
ExpressionAttributeValues: { ':url': jobURL }
});
if (urlMatch) {
return {
isDuplicate: true,
matchType: 'url',
message: 'You already tracked this exact job posting'
};
}Result: 🔗 Exact URL Match Confidence: 100% (definitely the same job)
Tier 2: Role + Company + Month Match (Secondary)
// If no URL match, check for same role in same month
const now = new Date();
const monthStart = new Date(now.getFullYear(), now.getMonth(), 1);
const monthEnd = new Date(now.getFullYear(), now.getMonth() + 1, 0);
const roleMatch = await dynamoDB.scan({
FilterExpression: 'Role = :role AND Company = :company AND DateApplied BETWEEN :start AND :end',
ExpressionAttributeValues: {
':role': role,
':company': company,
':start': monthStart,
':end': monthEnd
}
});
if (roleMatch) {
return {
isDuplicate: true,
matchType: 'role_month',
message: 'You already applied to this role at this company this month'
};
}Result: 📅 Same Role This Month Confidence: ~80% (probably the same, but could be different posting)
URL Match (Definite Duplicate):
┌───────────────────────────────────────┐
│ 🔗 Exact URL Match │
├───────────────────────────────────────┤
│ You already tracked this exact job │
│ posting for Software Engineer at │
│ Google on 2025-10-01. │
│ │
│ This is the exact same job posting │
│ you tracked before. │
└───────────────────────────────────────┘
Role/Month Match (Possible Duplicate):
┌───────────────────────────────────────┐
│ 📅 Same Role This Month │
├───────────────────────────────────────┤
│ You already applied to Software │
│ Engineer at Google this month on │
│ 2025-10-01. This might be the same │

│ │
│ This might be the same position or a │

Input:
{
"pageContent": "full page text (truncated to 8000 chars)",
"url": "https://...",
"title": "Page Title"
}Prompt:
Analyze this webpage and determine if it's a job application/posting page.
Task: Determine if this is a SPECIFIC job posting page (not a job search/listings page) and extract information.
Respond ONLY with valid JSON:
{
"isJobPage": true/false,
"confidence": 0-100,
"role": "extracted job title or null",
"company": "extracted company name or null",
"reasoning": "brief explanation"
}
Rules:
- isJobPage should be TRUE only if this is a SPECIFIC job posting with a single role
- Extract exact job title (without company name)
- Extract company name
- Keep reasoning brief (max 1 sentence)
Output:
{
"success": true,
"isJobPage": true,
"confidence": 92,
"role": "Software Engineer",
"company": "Google",
"reasoning": "Contains detailed job description with specific requirements and application process"
}When: After pattern-based detection succeeds
Flow:
1. Pattern detects job page ✓
2. Show "🤖 AI extracting job details..."
3. Send page content to AI
4. AI analyzes and extracts data
5. Compare AI data vs pattern data
6. If AI confidence ≥ 50%:
- Use AI data
- Show corrections (if any)
7. If AI confidence < 50%:
- Keep pattern data
- Show warning
8. Continue to duplicate check
9. Show form with verified data
Improvements Shown:
if (patternRole !== aiRole) {
console.log(`✓ AI corrected role: ${patternRole} → ${aiRole}`);
}
if (patternCompany !== aiCompany) {
console.log(`✓ AI corrected company: ${patternCompany} → ${aiCompany}`);
}When: User clicks "AI Verify" button (on not-detected pages)
Purpose:
- Verify pages not caught by patterns
- Override pattern detection
- User-initiated confidence check
Flow:
1. User clicks "AI Verify" button
2. Show "🤖 AI Analyzing Page..."
3. Send page content to AI
4. AI determines if job page
5. If yes (confidence ≥ 70%):
- Show verified data
- Display form
6. If no (confidence < 70%):
- Show "Not a Job Posting"
- Suggest trying another page
Two-Tier Approach:
-
URL Match (Primary)
- Most reliable
- 100% confidence it's same job
- Checks exact URL string match
-
Role + Company + Month (Secondary)
- Catches same position with different URL
- Useful for repostings
- ~80% confidence it's same job
Backend Logic:
// STEP 1: URL Check
const urlResult = await dynamoDB.scan({
FilterExpression: 'JobURL = :url',
ExpressionAttributeValues: { ':url': jobURL }
});
if (urlResult.Items.length > 0) {
return { isDuplicate: true, matchType: 'url' };
}
// STEP 2: Role/Company/Month Check
const monthStart = new Date(year, month, 1).toISOString().split('T')[0];
const monthEnd = new Date(year, month + 1, 0).toISOString().split('T')[0];
const roleResult = await dynamoDB.scan({
FilterExpression: 'Role = :role AND Company = :company AND DateApplied BETWEEN :start AND :end',
ExpressionAttributeValues: {
':role': role,
':company': company,
':start': monthStart,
':end': monthEnd
}
});
if (roleResult.Items.length > 0) {
return { isDuplicate: true, matchType: 'role_month' };
}
return { isDuplicate: false };URL Match:
- Strong warning: "This is the exact same job posting"
- Red exclamation icon
- Shows previous application date
- User can still save (edge case: reapplying)
Role/Month Match:
- Softer warning: "This might be the same position"
- Yellow info icon
- Shows similar application from this month
- Encourages verification
- Reapplying to same job: User can save anyway
- Similar roles at same company: Month filter catches these
- Same role, different company: Not flagged (different job)
- Same role, different month: Not flagged (could be reposting)
- Missing data: Graceful fallback (URL check only)
