Powerful Features

Everything you need to simulate authentic human typing behavior

Bypass Typing Analysis Systems

Designed specifically to evade typing-process detectors like GPTZero typing analysis. Simulates authentic human timing patterns, natural edits, and realistic corrections to minimize detection signals. Perfect for maintaining privacy in your typing behavior.

Realistic Typos
Randomly hits neighboring keys on QWERTY keyboard and automatically corrects them naturally, just like a real human would.
Variable Speed
Randomized delays between keystrokes with longer pauses at sentence boundaries and commas for authentic rhythm.
Mid-Sentence Edits
Goes back to change words, insert phrases, or improve text mid-typing for genuine human behavior patterns.
AI-Powered
Optional Gemini API integration for intelligent word suggestions and natural sentence rephrasing capabilities.
Keyboard Shortcuts
Pause, speed control, and emergency stop with intuitive keyboard shortcuts during active typing sessions.
File Loading
Load text from files or paste directly. Supports multiline text with proper formatting and structure.
