Large-Language-Models such as ChatGPT are diluting human-generated content on the internet. TYPECHA verification provides a certificate of human authorship.

Each TYPECHA verification includes a link to a certificate hosted on typecha.com, which you can share along with your content on any platform.

TYPECHA stands for Typing Yielding Persuasive Evidence Confirming Human Authorship. The TYPECHA verification process analyzes the revision history, typing patterns and content of a document to determine if it was written by a human.
