PhotoProof
PhotoProof is an AI-based digital forensics tool designed to distinguish authentic photographs from AI-generated or manipulated content. As synthetic media becomes more prevalent, PhotoProof provides an automated detection service that analyzes images and text for signs of artificial generation, editing, or deepfake manipulation. Users upload content directly through the web interface, and the system returns a probabilistic report with an AI-likelihood score, supporting signals, and guidance for further verification. The service also plans to support video detection in the future. PhotoProof employs a multi-layered analysis approach, running five complementary checks on every uploaded image: a visual AI pattern check examining synthetic textures and lighting; a metadata inspection reviewing camera, software, and editing metadata; a scene consistency check evaluating realism, object coherence, and anatomy; an image source type estimation identifying whether the file is a camera shot, screenshot, or recapture; and an editing check that detects retouching, compositing, and recompression artifacts. These layers are evaluated against patterns from leading generative models including Midjourney, DALL-E 3, Stable Diffusion, Adobe Firefly, and others. For text inputs, PhotoProof checks for AI-writing patterns and style signals, providing a similar probabilistic assessment. The platform is privacy-conscious: data is encrypted in transit, uploaded images may be stored privately for up to 24 hours solely for analysis and source searching, and text inputs are not stored as raw text. Users can start with a free account that includes three image or text checks without requiring a credit card. The service emphasizes that results are not absolute proof but rather risk signals meant to be used alongside context and human review.
