humantag.io is a privacy-first platform for anonymous cryptographic Proof of Humanity. We let real people generate a signed tag that proves they’re human without any personal data, IDs, or biometrics. Unlike Worldcoin, it works on any device with no extra hardware. It stores nothing and delivers instant, verifiable proof of human presence. Built for the AI era to separate real humans from bots - a true liveness check. No data. No surveillance. Just pure cryptographic truth.
