Short answer: no. GPTZero is a text detector. When we checked gptzero.me on 30 September 2026, its product list was AI Detector, Hallucination Detector, Plagiarism Check, Authorship & Writing Replay, Expert Feedback, Grammar Checker, a Chrome extension and AI Vision. None of them is an image detector. To check a picture, use a tool built for images, such as Imagera's AI Image Detector (15 credits a scan). If the problem is your own AI image looking fake, fix the image with the AI Image Humanizer.
What GPTZero's "AI Vision" actually does
The name suggests images, which is why "GPTZero image" gets searched so often. The AI Vision page describes something else: a Chrome extension that "scans the text on your feed as you browse and highlights what's AI-generated" on sites like Reddit, LinkedIn, X, Medium and Substack. It reads posts, not pictures.
GPTZero's detector scores writing. A photo has no sentences to score, so uploading a picture to a text detector tells you nothing useful about the picture.
GPTZero vs ZeroGPT: two different companies
The names are easy to mix up. ZeroGPT is a separate company, and its site does list an "AI Image Detector" to "detect AI-generated images and edited visuals". If you searched "zero gpt image detector", that is probably the tool you meant.
Tools that check images
| Tool | What it returns | Worth knowing |
|---|---|---|
| Imagera AI Image Detector | AI probability from 0 to 100%, a confidence figure, a label and the visual signals behind them | A vision model inspects light, texture, anatomy and text in the picture. 15 credits a scan |
| Hive | Confidence scores and, when available, the likely model | Free Hive Detect uploads and a Chrome extension; APIs for platforms |
| Illuminarty | Probability of AI generation | Free plan covers image classification; paid plans add region detection and model identification |
No detector is certain. Imagera does not publish an accuracy percentage for its detectors, because it has not run a benchmark that could support one. Use the score as one piece of evidence. Our AI image detector comparison covers why scores disagree.
If your own AI image looks fake
Often the real question is about your own work: you made an image with AI and want it to look like a photograph, for a product page, a portfolio or a social post. The tells that make people (and detectors) doubt an image are mostly visual:
- Waxy skin with no pores, freckles or stubble
- Light that comes from nowhere, with shadows that don't match the scene
- Too-clean surfaces: no sensor grain, no lens character
- Uniform sharpness from foreground to background
Before and after from the AI Image Humanizer demo: same photo and pose, only the skin rendering and grain change.
The AI Image Humanizer reads the photo first, then removes the plastic AI look (skin, light and lens) in one pass. If the composition must not move at all, for example a frame that has to match real footage, use Real Film Grain instead: it adds camera sensor grain and leaves composition and colour as they are.
A workflow that holds up
- Scan the original with the AI Image Detector and read which signals it lists.
- Humanize in Sandbox. The credit cost shows on the button before you run.
- Compare the result with the original at 100% zoom: face, hands, text and edges.
- Disclose AI use wherever a platform, client or contest asks for it.
No tool can promise that an image will pass a particular detector. Detectors are retrained, and scores shift with compression and edits. The humanizer makes an image look more like a photograph to a person. It is not a way around disclosure rules.
What it costs
Detection scans and humanizer runs use credits. The Starter plan is $19.99/mo for 300 credits, and credit packs start at $39.99 for 350 credits. See pricing.
