AI Waiver Detection

Stop Signing Away Your Rights

GCs send waiver requests buried in emails. AI automatically detects them, classifies conditional vs unconditional, matches them to jobs, and flags dangerous ones before you sign. No waiver slips through unnoticed.

  • AI detects waivers in emails automatically
  • Classifies: Conditional vs Unconditional
  • Classifies: Progress vs Final
  • Auto-matches to the right job
  • Red flags unconditional before payment
  • Alerts you before you sign something dangerous
Intent to Lien

The Letter That Gets You Paid

When a GC ghosts you, send a Notice of Intent to Lien. It's a formal "pay me or I file" letter—and it works. Most contractors get paid within 10 days. No lawyer required.

  • State-compliant demand letter
  • Proper statutory language included
  • 10-day payment deadline (varies by state)
  • Sent USPS Certified with tracking
  • Often gets you paid without filing
