Olumba

Know what the plan checker
will flag — before you submit.

Plan Proof reads your drawings and flags likely corrections before the city does — built by a PM who spent 10 years tracking plan check corrections by hand.

  • Upload a plan set — Plan Proof reads the drawings and flags likely corrections in minutes
  • Checks grounded in real correction letters from your jurisdiction, not generic code checklists
  • Catch issues before you submit — not three weeks later in a correction letter
  • Backcheck a revised set to confirm every flagged item is actually resolved

“I spent 10 years as a PM manually tracking plan check corrections — highlighter, spreadsheet, the whole routine. Every project, every revision. I built Olumba to handle what I used to do in 6 hours, in under 15 minutes.”
