Proof of Human is a forensic document auditing tool designed to cryptographically verify the authenticity of text authored in Google Docs™. In an era of AI-generated content and rapid copy-pasting, this add-on provides mathematical proof of human effort.

Core Capabilities:

Real-Time Typing Radar: Monitors keystroke velocity and flags unnatural text injections (jumps of >40 characters) while seamlessly ignoring images and native formatting.

Forensic History Scans: Interrogates the Google Drive™ Revisions API upon launch to detect "pre-sidebar" pasting and unnatural text-to-revision ratios.

Cryptographic Certification: Generates a permanent, in-document audit table featuring a unique SHA-256 Certificate ID, finalizing your humanity score, document length, and synced cloud save points.

Ideal for academia, legal professionals, journalists, and anyone requiring undeniable proof of original, human-generated work. Your data remains strictly local; we do not store, sell, or transmit document contents to external servers.
