What We Deliver

✅

Schedule Validation

Compare what's drawn (visual detection) against what's scheduled (typed text). Mismatches become "Areas of Concern" — flagged before permit approval.

📝

Draft RFI Generation

When we detect discrepancies, we generate draft language for your RFI. Copy, review, send — save hours of writing.

🔒

On-Premise Deployment

Permit documents never leave your network. Docker-based deployment, air-gapped support available. Your data sovereignty guaranteed.

⚙

Custom Rules

Configure detection thresholds and validation rules for your jurisdiction. Different codes, different requirements — one system.
