Independently Tested AI Image Detector
What an independent test found
Updated October 2026
1stof 7 tools tested by WebsitePlanet
In WebsitePlanet's independent test (last updated February 2026), Is It AI? had the best average accuracy of the seven tools tested: four AI image detectors and three AI chatbots. It called every image it was given correctly, both the AI-generated ones and the real photos.
WebsitePlanet ran fewer images through Is It AI? than through some other tools, because it only used our free checks, and it says results may vary on larger sets. Treat it as one independent result, and try the detector on your own images.

Coverage
AI Image Detector for 20+ Generators
Our detection engine is trained on the latest models from every major AI image generator, with version-level precision. Whether it's Midjourney's photorealism, DALL-E's creativity, or Stable Diffusion's open-source variants, we identify the source with precision. It doubles as an AI art detector and AI picture checker, flagging AI-generated illustrations as readily as photos.
- Midjourney v5, v6, v7
- DALL-E 2, 3
- Stable Diffusion 1.5, 2.1, SDXL, SD3
- Adobe Firefly 2, 3
- Flux.1 Dev, Schnell, Pro
- Google Imagen 2, 3
- Ideogram 2.0, 3.0
- ChatGPT 4o image, Grok Imagine, Nano Banana, Kling AI
- StyleGAN-family & other emerging generators
Analysis
Detailed AI Image Analysis
Go beyond simple AI/Human labels. Our AI image detector uses a multi-model pipeline to analyze pixel-level patterns, compression artifacts, and generation signatures. When you want to know whether an image is AI or not, or ask "is this image AI?", you get a likely verdict, a score out of 100 and the generator it most likely came from, instead of judging by eye.
- A score out of 100
- Specific AI method identification
- NSFW content flagging
- Results in under 3 seconds
- Detected method
- Midjourney

How Our AI Image Detector Works
Three simple steps to detect AI-generated images
-
Upload
Upload Your Image
Drag & drop an image, browse your files, or paste a URL. We support JPEG, PNG, WebP, and GIF formats up to 5MB. Your first 3 checks need no account.
-
Analyze
AI Analyzes the Image
Our multi-model detection pipeline examines pixel-level patterns, compression artifacts, metadata, and generation signatures. The entire analysis completes in under 3 seconds.

Get Your Results
Receive a likely verdict (AI-generated or human-made) with a score out of 100, the generator the image most likely came from (e.g., Midjourney), and NSFW content flags. Share or save your results.
Why It Matters
Why AI Image Detection Matters
AI images now pass a careful look
The old tricks
Count the fingers, look for garbled text, trust your gut. For a while, that caught most AI images.
They stopped working
New generators draw hands, text and skin that look right, so a careful look is often not enough to tell.
Check the image itself
Is It AI? looks for the patterns generators leave in the pixels, then gives a likely verdict and names the generator the image most likely came from.

Who Uses Our AI Image Detector?
From newsrooms to classrooms, professionals rely on accurate AI image detection every day.
Journalists & Media
Verify the authenticity of images before publishing. Protect editorial integrity in the age of AI-generated content.
Start detecting →Educators
Check images in student work as one signal to weigh before you talk to the student, not as proof on its own.

Why Is It AI?
What sets us apart from other AI detection tools
20+ AI Models
While most detectors check for one or two models, we cover Midjourney, DALL-E, Stable Diffusion, Nano Banana, Firefly, ChatGPT, Flux, and more.
Method Identification
We don't just tell you it's AI. We name the generator the image most likely came from, such as Midjourney or DALL-E.
Privacy First
Detection results are saved to your history, which you can delete at any time. If you turn on Save images, your images are kept with your history so you can see them again. Otherwise, images kept to improve our detection models are not linked to your account.
AI Image Detector FAQ
Common questions about detecting AI-generated images
Our AI image detector achieves 95%+ accuracy across major AI generators including Midjourney, DALL-E, Stable Diffusion, Nano Banana, and ChatGPT. Accuracy may vary based on image quality, resolution, and post-processing applied. We continuously update our models to keep pace with new generators.
We support JPEG, PNG, WebP, and GIF formats. Maximum file size is 5MB per image. You can upload files directly from your device or paste an image URL for remote analysis.
Detection results (score, label, and metadata) are saved to your history, and you can delete them at any time from your account settings. If you turn on Save images, your images are kept with your history so you can see them again. Otherwise, images kept to improve our detection models are not linked to your account.

Upload any image or paste an image URL into our AI image detector. Our multi-model pipeline analyzes pixel-level patterns, compression artifacts, and generation signatures to determine whether the image was created by AI or a human. You get results in under 3 seconds, including a confidence score and the specific AI generator identified. No signup is required for your first detection.
In WebsitePlanet's independent test of seven tools (last updated February 2026), Is It AI? had the best average accuracy and called every image it was given correctly. The test used a small number of images per tool, and accuracy varies by tool and generator, so we recommend testing with your own images.
While no AI image detector is perfect in every scenario, our multi-model approach makes it significantly harder to bypass detection. Factors like heavy post-processing, extreme compression, or screenshots of AI images can reduce accuracy. We continuously update our detection models to stay ahead of new generation techniques and adversarial methods.
Yes, our AI image detector can identify AI-generated images including deepfakes created by tools such as Midjourney, DALL-E, Stable Diffusion, Nano Banana, and face-swapping models. The detector analyzes visual artifacts and generation signatures that are characteristic of AI-created content, including deepfake imagery.
Paste or upload the image into our AI image checker. It returns a confidence score showing whether the picture is AI-generated or a real photo, usually in under 3 seconds.
An AI image checker (also called an AI image detector) analyzes a photo's pixel patterns and generation signatures to estimate whether it was made by an AI tool like Midjourney or DALL-E, rather than captured by a camera.
Yes. You can run your first detections free with no signup, and a free account gives you 5 image checks every month. Upload a photo or paste an image URL to get an instant AI-or-real result.
Yes. The same detector works on AI art and illustrations as well as photos. It flags the pixel-level patterns that image generators leave behind, whether the source is Midjourney, Stable Diffusion, or another model.
Use our online AI image detector right in your browser, with no install needed. Upload the image or paste its URL and you'll get an AI-probability score plus the likely generator.
