Independently Tested AI Image Detector
Verified accuracy you can trust, not just claims
In an independent study by WebsitePlanet (February 2026), Is It AI? was named the best-performing AI image detector of seven detectors tested. Our detector correctly identified AI-generated images across all categories and generators in the study, achieving a perfect 100% score on AI-generated images.
Unlike competitors who cite their own benchmarks, this result comes from a third-party evaluation that compared seven of the most popular AI image detection tools on the market.

02 Analysis
Forensic-Level 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 so you know exactly what you're looking at. When you need to settle whether an image is AI or not, or ask "is this image AI?", you get a clear, evidence-backed answer instead of a guess.

05 Why It Matters
Why AI Image Detection Matters
The rise of AI-generated images demands reliable detection tools
AI-generated images are created every day using tools like Midjourney, DALL-E, and Stable Diffusion. Without an AI image detector, distinguishing real from fake is nearly impossible.
Increase in AI-generated deepfakes since 2023. From fake news imagery to fraudulent product photos, AI images are being used to deceive at an unprecedented scale.
Of people cannot reliably tell the difference between AI-generated and real photos. An AI image detector provides the objective analysis that human eyes cannot.

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 an independent study by WebsitePlanet (February 2026), Is It AI? was named the best-performing AI image detector tested, achieving a 100% score on AI-generated images across the categories tested. The study compared seven detectors; accuracy varies by tool and generator, so we recommend testing with your own images to compare.
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.
