not.bot app

Anyone can verify, free.

Checking a not.bot™ signature costs nothing and works anywhere, with no account required. In the US, the app also lets you enroll and become a verified human: prove you are real once, then clear the human check on any not.bot site.

Verify any signature.

Scan signed content and confirm it is genuine. Free, worldwide, no account needed.

Become a verified human.

In the US, enroll once with your passport. Then clear the human check on any not.bot site, with no selfie or upload each time.

Sign a message.

Enrolled users can sign a message right in the app, so the person reading it knows it came from a real, verified human.

Enrollment

Prove you are real once.

Enrollment reads the chip in your government passport and confirms it with a certified identity partner. Your identity data stays on your phone. You become a verified human without handing your identity to a database.

Verifying signatures works worldwide today. Enrollment is available in the US, with more countries on the way.
