Lucid
AI & Scam Detector
AI-powered scam and fraud detector that analyzes messages, calls, and links in real-time to protect you from threats. All processing happens on-device — your data never leaves your phone.
How Lucid Protects You
Real-time AI threat detection — all on your device, zero data sent to the cloud.
AI Scam Detection
On-device AI models analyze incoming messages and calls in milliseconds, identifying scam patterns, social engineering tactics, and fraud indicators before they reach you.
Link Analysis
Every URL shared via SMS, chat apps, or email is analyzed for phishing indicators, malicious redirects, and fake domains before you tap. No cloud lookup required.
Call Screening
Lucid screens incoming calls in real-time and alerts you to suspected fraud calls, robocalls, and spoofed numbers — giving you full context before you answer.
SMS Phishing Guard
Automatically scans incoming SMS messages for smishing attacks, fake delivery notifications, bank impersonation, and other text-based fraud schemes.
On-Device Processing
All AI analysis runs entirely on your device. Your messages, calls, and browsing activity never leave your phone — no server uploads, no logs, no surveillance.
Privacy-First Design
No accounts required, no data collection, no ad tracking. Lucid is built on the principle that your security tool should never become a surveillance tool itself.
Stay Protected
Three simple steps to full scam protection.
Install Lucid
Download from Google Play. No sign-up, no account — protection starts immediately on install.
Enable Protection
Grant the permissions you want — SMS, calls, or both. Lucid only uses what you enable and nothing more.
Stay Protected
Lucid runs silently in the background, alerting you only when a real threat is detected. No false alarms, no noise.
