Half the content on major platforms is synthetic now. I built a social network that forensically proves every post is human.
The Dead Internet Theory used to be a fringe idea. Meta putting AI personas in feeds as a feature made it corporate policy. I spent six months building a social media app that goes the opposite direction. SocialHuman forensically verifies every post before it goes live. Seven analyzers: EXIF forensics, moire detection, sensor fusion, keystroke dynamics, video forensics, audio validation, and C2PA attestation. The app has no gallery picker. Camera-only capture. The text field blocks paste and rejects input that doesn't match human typing patterns. Every verified post gets a trust score and a shareable proof receipt.
What I've learned building this: the technical verification is actually the easy part. The hard part is the cold-start problem. You're building a social network from zero, and the value proposition only works when there's enough content to make a feed worth opening. It's a chicken-and-egg situation where the eggs need to be forensically verified. Still early. Still small. But it works and the verification pipeline catches everything I've thrown at it.
