In a world of deepfakes and AI impersonation, trust is under attack. PYAH uses live challenge-response verification to prove real-time human presence — without storing a single byte of your personal data.
Three steps to cryptographic proof of humanity. No accounts required.
Choose a use case and generate a unique verification link. Send it to anyone you need to verify.
The responder performs randomized physical actions on camera — gestures, movements, expressions.
Receive a timestamped, cryptographically signed certificate proving humanity. Valid for 24 hours.
Every feature designed to combat AI impersonation while protecting your privacy.
Perform unpredictable physical actions captured via webcam to prove real-time human presence.
Generate unique 'Prove It' challenge URLs to send to anyone via text, email, or chat.
Cryptographic proof of humanity with timestamp, challenge type, and validity period.
Prove you're human without revealing your identity. No biometric data stored.
Pre-configured flows for dating, hiring, emergency calls, and marketplace transactions.
Track all sent and received verification requests with status and timestamps.
Unpredictable action combinations prevent AI prediction or replay attacks.
Instant verification with on-screen instructions and live feedback during challenges.
Pre-configured verification flows tailored to real-world scenarios.
PYAH never stores biometric data, facial recognition templates, or personal information. Verification is based on real-time challenge completion — not identity. Your humanity is proven through action, not surveillance.
