IsThisAPhoto

IsThisAPhoto is a free, no-signup web tool designed to help users quickly determine whether an image is likely AI-generated. Its positioning is a straightforward, transparent AI photo detector that provides not just a probability score but also plain-English explanations of the detection signals, confidence levels, and possible generator-specific evidence when available. The target audience includes everyday internet users, social media users, online daters, marketplace shoppers, journalists, fact-checkers, and anyone who wants a second opinion before trusting or sharing an image. Core features include drag-and-drop or clipboard upload for JPG, PNG, and WebP files up to 4 MB, server-side analysis via Sightengine's genai model, a 0–100% AI probability score, a cautious verdict (including Inconclusive for uncertain scores), and notes on detection signals. Content features emphasize honest limitations, no heatmap or C2PA provenance, and the reminder that a score is one clue rather than proof. User experience is simple and frictionless: no account, no paywall, 10 checks per IP per UTC day, clear error/limit messages, and a mobile-friendly interface. Technical features include in-browser preview, secure server function forwarding, no storage of images or results by IsThisAPhoto, and integration with Sightengine's AI-generated image detection API. The site also links to privacy, terms, contact, and API/pricing pages.
