Copyseeker

Copyseeker is a free image analysis service combining reverse image search, AI-generated image detection, NSFW screening and text extraction, with REST APIs, a Chrome extension, an iOS app and a custom GPT.

Copyseeker is an image analysis service that answers four questions from a single upload box: where a picture came from, whether an AI model made it, whether it contains explicit content, and what text appears inside it. Files can be uploaded or pasted as a URL, and searching does not require an account. The reverse image search is the core product. Instead of comparing file hashes, it matches on what the picture depicts, so cropped, recoloured, watermarked or repeatedly recompressed copies can still lead back to the source. Matching pages are ranked by the authority of the site hosting them, which pushes the likely original above scrapers and aggregators. When the file still carries EXIF metadata, capture date and GPS location are returned next to the matches. The AI detection tool gives a verdict plus a confidence score from 0 to 100 percent, and is tuned to traces left by Midjourney, DALL-E and Stable Diffusion. NSFW detection returns a safe or not-safe result with a confidence value so teams can set their own auto-block threshold. Text extraction turns signs, documents, screenshots and social posts into searchable text in more than 50 languages. The audience is wide. Journalists and moderators verify photos before publishing, brands look for product images used without permission, researchers check whether a picture is real or altered, and ordinary users check suspicious profile photos or listings. Developers can call the reverse search, AI detection and NSFW tools as REST endpoints that return structured JSON, with custom rate limits for high volume. The service also ships as a Chrome extension, an iOS app and a custom GPT, and the interface is offered in a dozen languages. Uploaded files are deleted within 24 hours. Among alternatives, it competes with general reverse search engines and with standalone AI-image checkers, but bundling both with moderation and OCR under one API is its distinguishing trait.
