RealStamp
Prove a human made it — cryptographic provenance, live.
RealStamp is the proof-of-human credential built for the AI era. A verified human cryptographically signs any photo, video, or text at the moment of capture - Face ID + Secure Enclave on iOS, biometric + Android Keystore on Android - producing portable proof anyone can verify offline. C2PA-compatible. Live today on iOS, Android, web, WordPress, and Chrome. Engineered for EU AI Act Article 50, in force August 2.
Hey Product Hunt!
I'm Emilia, founder of Skillecta and primary architect of RealStamp.
For a year I watched the AI-watermarking war get fought generator-side - Adobe Content Credentials, C2PA, SynthID. A 2025 IEEE Security & Privacy paper ("UnMarker") finally showed what most of us suspected: pixel watermarks are universally removable. The "is this AI" problem isn't solvable by marking AI output.
So I built the inverse.
RealStamp is the proof-of-human credential. A verified human cryptographically signs any photo, video, or text at the moment of capture - gated by a fresh Face ID or biometric ceremony, hardware-bound to the Secure Enclave (iOS) or Android Keystore, anchored to the Sigstore Rekor public transparency log (Linux Foundation). The result is a portable SD-JWT verifiable credential anyone can verify offline. No account, no platform login.
Live today: iOS, Android, web app + REST API, WordPress plugin, Chrome extension, @realstamp/verify on npm.
Two USPTO patents pending - including one on verifiable human authorization of autonomous AI-agent actions (because agents are the next regulated surface).
EU AI Act Article 50 enters force August 2. RealStamp's SD-JWT is exactly what the EU Code of Practice accepts as a Provenance Certificate.
Important: it is NOT anti-AI. AI-generated content stamped by a human who took editorial responsibility for it is fully valid - that's the human authorship Article 50(5) recognizes.
Free tier everywhere. Premium from $9.99/mo.
I'd love your honest thoughts - what's the use case where you'd want to verify a real human made the content? Photographers? Journalists? Founders launching their own product? Tell me where the friction is.
