not.bot is how we know who's not a bot online.
Deepfakes and AI-generated content are becoming indistinguishable from reality.
not.bot provides cryptographic proof that you're a real human.
Sign content and interactions using cryptographic methods that AI will never be able to replicate.
Create different aliases for different contexts. No one can tell they belong to the same person - not even us.
Share your name, gender, or other information - or share nothing except proof that you're not a bot. You decide.
Include clear messages describing what you're signing. If used out of context, anyone can verify it's invalid.
Anne Murphy created a not.bot sticker for AI Festivus with the message: "AI Festivus, December 26-27, 2025". She included her first and last name and gender. If someone tries to copy that sticker and use it somewhere else, anyone who scans it will immediately see the context doesn't match - proving it's being misused.
not.bot is currently in early access and available only on Apple iOS.
