TruthLens helps you inspect whether an image carries AI provenance, Content Credentials, EXIF metadata, XMP data, software tags, or suspicious file-structure signals. Designed for privacy-first image verification, TruthLens analyzes JPEG and PNG files locally on your device. Your image is not uploaded to a server. TruthLens prioritizes provenance-based evidence such as C2PA metadata and known AI tool signals from providers including OpenAI and other image-generation pipelines. It also checks camera metadata, software markers, file structure, and metadata sparsity to produce a clear, easy-to-understand result. Key features: • Local image analysis • C2PA and Content Credentials inspection • EXIF, XMP, PNG, and JPEG metadata checks • AI provenance signal detection • Clear verdict, confidence score, and evidence list • Exportable detection report TruthLens provides heuristic provenance assessment, not forensic or legal certification.
