# ProofStream > ProofStream is a human-in-the-loop (HITL) verification service. We send trained personnel to physically verify products, properties, assets, and documents — delivering timestamped photo/video evidence and detailed reports. Optional livestream lets clients watch verification happen in real time. ProofStream operates at [proofstream.ai](https://proofstream.ai) and is based in the United States. ## Services ProofStream offers three verification service tiers: ### Product Verification - **What**: In-person authentication and condition assessment of physical products (electronics, luxury goods, vehicles, collectibles, equipment) - **Standard**: $39 — photos, measurements, condition report - **Livestream**: $79 — real-time video feed of verification process - **Turnaround**: 24–48 hours (standard), scheduled (livestream) ### Property & Asset Verification - **What**: On-site inspection of real estate, commercial property, land, or high-value assets - **Standard**: $249 — photos, measurements, condition documentation - **Livestream**: $349 — real-time walkthrough with client viewing - **Turnaround**: 48–72 hours (standard), scheduled (livestream) ### Document Verification - **What**: Physical verification of documents, certificates, permits, licenses, or records at their source location - **Standard**: $99 — photos, authenticity indicators, verification report - **Livestream**: $149 — real-time document review - **Turnaround**: 24–48 hours (standard), scheduled (livestream) ## How It Works 1. **Request**: Client submits verification request with item/location details 2. **Assign**: ProofStream dispatches trained verification personnel to the location 3. **Verify**: Personnel conduct in-person verification with photo/video evidence 4. **Report**: Client receives timestamped verification report with evidence package 5. **Livestream** (optional): Client watches the entire process live via secure video feed ## Key Differentiators - **Human-in-the-loop**: Every verification is performed by a trained human on-site — not AI, not automated - **Livestream capability**: Watch verification happen in real time via secure encrypted video - **Timestamped evidence**: All photos and videos include GPS coordinates and timestamps - **Fast turnaround**: Most verifications completed within 24–72 hours - **Nationwide coverage**: Service available across the United States ## Use Cases - Online marketplace buyers verifying product condition before purchase - Real estate investors confirming property condition remotely - Insurance companies verifying claims with independent on-site evidence - Legal teams obtaining documented proof of physical conditions - Supply chain managers verifying inventory or asset status - Remote buyers authenticating luxury goods, vehicles, or equipment ## What ProofStream Is NOT - Not a legal opinion or professional appraisal service - Not a certification or authentication authority - Not an automated or AI-only verification system - Reports document observable conditions; they do not constitute professional valuations ## Technical Details - **Website**: https://proofstream.ai - **Request form**: https://proofstream.ai/request.html - **Payment**: Processed via Stripe (secure, PCI DSS compliant) - **Hosting**: Vercel (SOC 2 Type II) - **Contact**: verify@proofstream.ai ## Legal - [Terms of Service](https://proofstream.ai/terms-of-service.html) - [Privacy Policy](https://proofstream.ai/privacy-policy.html)
