RealStamp
Prove a human made it — cryptographic provenance, live.

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.
