Paragen - AI Revenue Leakage Detection

See Lost Revenue. Recover It. Automate It.

What Is Paragen?

Paragen is an AI-powered platform that automatically detects revenue leakage in your business documents. Upload contracts, invoices, and billing records - Paragen analyzes them to find pricing errors, missing charges, billing discrepancies, and contract deviations that cost you money.

Core Features

📄 Document Analysis

• Upload contracts, invoices, and billing records
• AI automatically extracts and analyzes data
• Identifies revenue leakage opportunities

🎯 Intelligent Detection

• Pricing Errors - Incorrect rates and tier miscalculations
• Missing Charges - Unbilled services and untracked usage
• Billing Discrepancies - Calculation errors and invoice mismatches
• Contract Deviations - Unearned discounts and invoice-contract misalignments

🔒 Enterprise Security

• AES-256 encryption for all files at rest
• PII auto-redaction before AI processing
• SQL injection & DDoS protection
• No data used for AI model training

💡 Smart AI Load Balancing

• Multi-provider AI routing (Groq → Gemini → OpenRouter)
• Prioritizes free tiers for cost efficiency
• Automatic fallback for reliability
