ProofsSnap

ProofsSnap creates tamper-proof, blockchain-verified records of your photos. Take a photo, and ProofsSnap instantly generates a cryptographic proof that it existed at that exact moment in time — anchored permanently on the Polygon blockchain. HOW IT WORKS 1. SNAP — Take a photo of anything: an accident, a document, property condition, or any moment you need to prove happened. 2. AI ANALYZES — On-device AI detects objects, recognizes text, and scores photo authenticity. Everything runs locally — your photos never leave your phone. 3. BLOCKCHAIN PROVES — A SHA-256 hash of your photo is batched into a Merkle Tree and anchored on the Polygon blockchain. This creates an immutable, independently verifiable proof of existence. KEY FEATURES - Blockchain-anchored photo proofs with Merkle Tree batching - On-device AI analysis: object detection, OCR text recognition, authenticity scoring - Privacy-first: only the cryptographic hash is sent to the server, never your actual photos - QR code generation for easy proof sharing and verification - Real-time proof status tracking with polling - Verify any proof by ID or QR code scan - Beautiful, intuitive interface with dark mode support - Location tagging for stronger evidentiary value USE CASES - Insurance claims: document accidents, damage, or property condition - Legal evidence: prove a document or situation existed at a specific time - Journalism: verify the authenticity and timing of photographic evidence - Real estate: record property conditions before/after - Personal records: create verifiable proof of any moment PRIVACY Your photos are analyzed entirely on your device. We never see, store, or transmit your images. Only a cryptographic fingerprint (SHA-256 hash) and metadata are sent to our server. No accounts, no tracking, no ads.
