Precision Matters

Intelligent Detection

Your beach photos and family pictures stay untouched. We only find what actually matters.

Advanced Detection

Leverages Apple's SensitiveContentAnalysis framework to identify nude and sensitive content with industry-leading accuracy.

Smart Filtering

Your beach photos, medical images, and art won't get flagged. The ML model is trained for precision—not paranoia.

Processing Speed

~1 second per photo on modern devices (A15+). Large libraries may take time, but accuracy is never compromised for speed. Every photo gets the full analysis it deserves.
