Advanced AI-powered Password Strength & Breach Detection Tool
(Example preview — replace with your own screenshot or deployed link)
AI Password Analyzer is an intelligent web application that analyzes your password strength in real time.
It uses entropy-based algorithms, pattern recognition, and optional breach detection (via k-anonymity API) — ensuring that your passwords are not only complex but truly secure.
The tool runs entirely client-side, guaranteeing 100 % privacy — no password ever leaves your device.
