ℹ️ About SSL Certificates

SSL (Secure Sockets Layer) certificates encrypt data between your browser and gptzero.us's server. A valid SSL certificate ensures that your connection is private and that you're communicating with the real Gptzero website.

Websites without valid SSL certificates may show browser warnings and are penalized in search engine rankings.
