Error Level Analysis (ELA) - Detect edited/manipulated regions in photos
Metadata Extraction - View EXIF, XMP, IPTC data including camera info, GPS, and AI generation parameters
Trust Score - Combined confidence score based on multiple analysis factors
Reverse Image Search - Quick links to Google, Bing, TinEye, Yandex image search
Content Credentials (C2PA) - Verify authenticated content provenance
