Score: 6.0/10 (Innovation: 7, Technical: 6, Documentation: 6, Utility: 5)

This project demonstrates a novel invisible CAPTCHA that analyzes mouse movements, typing rhythm, and button press patterns to distinguish humans from bots using an AI model (Jev). It provides a TypeScript tutorial and demo, showing promising results against simple bots but acknowledging limitations against sophisticated human-imitating bots. It's an interesting exploration of behavioral biometrics for bot detection.

Target audience: web developers, security engineers, AI researchers
