Proof helps you tell whether a quote, estimate, invoice, or bill is priced reasonably before you hand over money.
Take a photo or upload a PDF of a quote for auto repair, HVAC, plumbing, electrical, appliance repair, or home improvement work. Proof reads the line items and gives you:
• An estimated fair-price range, adjusted for your area
• A clear verdict — in range, a little high, or worth questioning
• Specific questions to ask the contractor
• A private history of everything you've checked
Your first check is free. Proof Unlimited is $3.99/month for unlimited checks.
Proof gives general, informational estimates only. It is not an appraisal or professional advice — always use your own judgment.
