The Human Keystroke Engine for Google Docs
Autonomously types AI and manual text character-by-character directly into Google Docs with authentic human cadence, thought pauses, and natural proximity typos.
Engine Features
Gaussian Cadence Modeling
Typing speed fluctuates naturally following human biomechanics. Inter-keystroke intervals follow a bell curve with micro-variance across hands and finger reach.
Synthesized Thought Pauses
Simulates authentic cognitive pauses at clause boundaries, punctuation marks, paragraph breaks, and after complex vocabulary words.
Proximity Typos & Fixes
Injects realistic adjacent QWERTY key slips (e.g. typing 'e' instead of 'r') and immediately executes realistic backspace corrections.
Google Docs DOM Hook
Interfaces directly with Google Docs' custom canvas and iframe text events, generating legitimate trusted KeyboardEvents that appear genuine to version history.
100% Zero-Telemetry Privacy
Your drafted essays, articles, and prompts are processed entirely in your local browser sandbox. No document contents are ever transmitted to external servers.
Fluid WebGL Interface
Crafted with bespoke WebGL fluid dynamics, smooth GPU rendering, and responsive real-time keystroke monitoring telemetry.
How It Works
