CertShield

Never work with an uninsured vendor again — AI-powered COI tracking for property managers & contractors.

Domain verified Dofollow

CertShield is an AI-powered platform that automates Certificate of Insurance (COI) verification and tracking for US property managers and contractors. Vendors send messy COI PDFs by email — staff then check limits, dates, and endorsements by hand, and certificates quietly expire. CertShield reads every certificate with AI, extracting limits, expiration dates, carrier details, and endorsements (CG 20 10, CG 20 37, waiver of subrogation, primary & non-contributory) with a confidence score. Anything low-confidence or failed automatically routes to human review — nothing is auto-approved without a real check. Once approved, CertShield tracks every certificate and automatically chases renewals via email (English + Spanish) before they expire, so vendors and agents get reminded without you lifting a finger. Key features: - AI document extraction with confidence scoring - Automated compliance checks across 6+ requirements per document - Human review for every low-confidence or failed check - Bilingual auto-chase email reminders - Audit-ready compliance reports, exportable in one click - Real-time dashboard showing vendor status (covered / expiring / needs fixing) Built for property management companies, HOA managers, and general contractors juggling multiple vendors. Plans start at $99/month with no annual lock-in — cancel anytime.
