Signatures survive distribution.
Even a screenshot of signed content still verifies, because the visible signature (patent pending) is a part of the file.
AI can make anything. A signature makes it authentic.
Malicious AI-generated content can hijack your brand. Signing your content is the only proactive defense. not.bot™ Signer makes it easy.

Sign your content wherever you publish it.
not.bot Signer makes it easy to sign everything your brand publishes: posts, images, video, even documents. You sign your content when you create it, and your signature travels with it everywhere.
A publicly-verifiable signature proves content is authentic, wherever your audience finds it, anywhere on the internet. Anyone can verify the signature worldwide with a free app (iOS & Android).
Unsigned becomes suspect.
The more of your content carries a signature, the less room a fake has to borrow your brand.
A fake is easy to refute.
Remind your audience of your content-signing policy to refute a deepfake without giving it the spotlight.

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