OriginSign lets you cryptographically sign any photo or video so you can prove it’s yours. No blockchain, no wallet, no downloads — just upload your media, sign it with your private key, and share it anywhere. Anyone can verify authenticity instantly at originsign.com/verify. In a world full of AI clones and stolen content, OriginSign gives creators a simple way to protect their work and prove originality.

👋 Hey Product Hunt! I’m Rami — the founder of OriginSign. I built OriginSign because creators are being flooded with AI clones, impersonators, and stolen content. There’s no simple universal way to say, “this is mine.” Watermarks can be removed. Metadata can be stripped. But cryptographic signatures? They stick. OriginSign makes that power accessible to anyone — no blockchain, no crypto, no setup headaches. Here’s the idea: • You sign your content using your keys. • The signature is embedded invisibly into the media. • Anyone can verify it instantly. • Your identity, your proof, your ownership. The goal? Make content authenticity the new standard — and help creators take back control in the AI era. I’d love your feedback, questions, or ideas. Thank you for supporting the launch! 🙏 — Rami
