Understand Your AI Image Detection Results
Unfox combines AI image probability with source trace analysis to give you more context behind each result. Review the overall classification, compare AI and real-photo scores, and check for available source or content credentials.
AI vs. Real Photo Probability
See how strongly the image matches patterns associated with AI-generated content compared with real photography. The scores reflect the detector’s assessment rather than absolute proof of origin.
Source Trace Analysis
Check for available signals linked to AI generators, content credentials, generation parameters, and image editing. Source traces provide additional context and do not determine the final detection result on their own.
Downloadable Detection Report
Download your detection result for easier review, documentation, or sharing. Use the report as supporting information rather than the sole basis for formal decisions.
How Our AI Image Detector Works
An AI image detector analyzes visual signals to assess whether an image is likely AI-generated or a real photo. Unfox combines AI-based image analysis with source trace checks to provide a probability-based result with additional context about the image.

AI Image Analysis
Unfox analyzes visual patterns associated with AI-generated and real images, then compares those signals to estimate the likelihood that an image was created with AI.
AI vs. Real Photo Probability
Get a clear probability comparison between AI-generated content and real photography instead of relying on a simple yes-or-no classification.
Source Trace Detection
Check for available traces associated with C2PA Content Credentials, AI generators, image editing, and embedded generation parameters to better understand an image’s possible source.
Popular AI Generator Coverage
Unfox checks for available source signals associated with tools such as DALL·E, Gemini, Midjourney, Stable Diffusion, Flux, and Adobe Firefly.
Batch Detection
Analyze multiple images more efficiently when you need to review larger volumes of visual content.

Digital Art
Review illustrations and digital artwork when you need more context about whether generative AI may have been involved.
Real Estate Photos
Check property and interior images that may contain AI-generated rooms, virtual staging, or heavily altered visual elements.
Receipts and Transaction Images
Screen receipts, invoices, and payment screenshots for potential AI-generated or edited visual content before further review.
Accuracy & responsible use
AI Image Detection Accuracy & Limitations
AI image detection is not an absolute test of image origin. Results can vary depending on the image, generator, editing history, and available visual or source signals, so Unfox results are best used as supporting evidence.
Image Quality Matters
Heavy compression, low resolution, repeated screenshots, or significant resizing can remove or alter signals used during detection.
Editing Can Affect Detection
Cropping, filters, retouching, and other edits may change patterns associated with the original AI-generated or real image.
AI and Real Content Can Be Mixed
Images that combine real photography with AI-generated or AI-edited elements can produce less certain or mixed detection signals.
AI Models Keep Evolving
New image generators and model updates can create visual patterns that differ from those seen in previously analyzed AI-generated images.
Detection Is a Signal, Not Proof
Use the probability score and source trace together with the image’s source and context rather than treating a single detection result as definitive proof.
Your Images Stay Private
Your images may contain personal, creative, or confidential information. Unfox is designed to keep image detection focused on analysis while minimizing unnecessary use of uploaded content.
Secure Image Processing
Uploaded images are processed securely during AI image detection to help protect your content throughout the analysis.
Built for Sensitive Visual Content
Check personal photos, creative work, documents, and other visual content with privacy in mind.
Clear Data Handling
We aim to make it clear how uploaded images are processed, stored, and handled so you can understand what happens to your content.
Privacy Across Every Check
Whether you analyze one image or use batch detection, the same privacy principles apply throughout the detection process.

FAQ
Frequently Asked Questions About AI Image Detection
01How accurate is an AI image detector?
AI image detector accuracy varies by image type, AI generator, image quality, and editing history. Unfox provides a probability-based assessment, so the result should be considered alongside source traces and other available context rather than treated as absolute proof.
02Can an AI image detector detect Midjourney, DALL·E, Gemini, or Stable Diffusion images?
AI image detection can identify patterns associated with images from popular generators such as Midjourney, DALL·E, Gemini, and Stable Diffusion. Detection confidence can vary between models and versions, especially as image generators continue to evolve.
03Can an AI image detector detect screenshots?
Yes, you can check screenshots, but screenshotting may remove metadata and alter visual signals through resizing or compression. For better AI image detection results, use the original image whenever possible.
04Can an AI image checker detect edited or compressed images?
It can still analyze edited or compressed images, but cropping, filters, retouching, resizing, and heavy compression may affect the signals used for detection. This can make some results less certain.
05Does an AI photo detector rely on metadata or watermarks?
Not necessarily. AI photo detection can analyze visual patterns even when metadata is unavailable, while available source traces such as content credentials, generator information, or embedded parameters can provide additional context. Missing metadata alone does not mean an image was AI-generated.
06What does the AI probability score mean?
The score represents how strongly the analyzed image matches patterns associated with AI-generated or real images. For example, a higher AI probability indicates stronger AI-related signals, but it does not prove who created the image or which tool was used.
07Can an AI image detector be wrong?
Yes. AI image detectors can produce false positives or false negatives, particularly with heavily edited images, screenshots, mixed AI and real content, or outputs from newer generators. Use detection as a supporting signal and verify important images with additional evidence. Independent testing has also documented false positives and reduced performance after image transformations.
08Is the Unfox AI Image Detector free?
You can start checking images with the Unfox AI Image Detector online. For higher-volume detection and additional features, choose the option that best fits your usage needs.
