Fight misinformation with professional-grade image verification. Origin Lens analyzes C2PA metadata and performs reverse image searches to help you determine if images are authentic, AI-generated, or taken out of context. C2PA VERIFICATION Origin Lens reads cryptographically signed Content Credentials embedded by cameras and AI tools. It detects AI-generated images from Adobe Firefly, Microsoft Designer, and Bing Image Creator. View complete edit history, original creator information, and validated digital signatures to ensure content has not been tampered with. AI DETECTION Multiple detection methods identify AI-generated content from major creation tools. Origin Lens analyzes C2PA metadata, EXIF data and SynthID to reveal which AI tool was used to create an image, giving you confidence in your verification. CONTEXT VERIFICATION Reverse image search across multiple search engines helps you find where images have appeared online. Detect out-of-context or misattributed images and identify viral misinformation. Smart filtering removes irrelevant results so you see only what matters. PRIVACY FIRST Images are analyzed locally on your device. Reverse image search uses external services only when you choose to run it. You can bring your own API keys for enhanced privacy. No data collection or tracking. PROFESSIONAL TOOLS Support for multiple image formats including JPG, PNG, HEIF, AVIF, and WebP. Analyze images from Files, Photos, or by entering a URL. Use the share extension for quick verification from other apps. View comprehensive EXIF metadata and detailed edit history. PERFECT FOR Journalists verifying sources. Researchers fact-checking visual content. Social media users combating fake news. Anyone who wants to verify image authenticity before sharing. HOW IT WORKS Select an image from your gallery, files, or enter a URL. Origin Lens instantly analyzes C2PA metadata and EXIF data. Optionally run reverse image search for additional context. Get clear results showing AI detection status, verification status, and edit history. WHY ORIGIN LENS With the rise of deepfakes and AI-generated content, knowing the origin of media is crucial. Origin Lens empowers you with professional-grade tools to fact-check visual content before sharing it. IMPORTANT NOTE C2PA detection requires images to have embedded Content Credentials. Most current AI tools do not yet support this standard. Screenshots and social media uploads strip metadata. For best results, use original downloaded files.
