Verdict
MyDetector ranks #2 among tested AI detectors with an overall accuracy of 81.9% across 199 images. It performs strongest against FLUX 2 Flex images (92% detection rate) but struggles with Firefly v4 content (only 0% detected). With a 7.7% false positive rate, it occasionally flags real photos as AI-generated.

Benchmark Methodology
MyDetector was evaluated on a curated dataset of 199 images across 3 AI image generators and 1 watermark types, including models like Midjourney, Stable Diffusion, DALL-E 3, Flux, and others. The dataset also includes real photographs from verified sources to measure false positive rates.
All detectors are tested under identical conditions using the same images. We record each detector's classification (AI or Real) and confidence score, then compute three key metrics: Accuracy (percentage of correct predictions), False Positive Rate (real images incorrectly flagged as AI), and False Negative Rate (AI images missed by the detector).

What is MyDetector?
MyDetector is a free AI content detection platform that offers text, image, and code detection tools. Their AI Image Detector uses deep learning to analyze pixel-level patterns, metadata, and image composition to determine whether an image was generated by AI or captured by a real camera.
The platform requires no sign-up and supports common image formats including JPG, PNG, and WEBP.
How MyDetector Works
MyDetector's AI Image Detector employs several analysis techniques:
Pixel-Level Analysis
- Texture gradient detection identifying unnatural smoothness or patterns typical of AI generators
- Artifact scanning looking for telltale signs left by diffusion models and GANs
- Color distribution analysis comparing pixel patterns against known AI generation signatures
Composition Analysis
- Structural consistency checks examining whether objects and backgrounds follow natural physics
- Lighting analysis verifying consistency of shadows and reflections
- Detail coherence checking for AI-typical issues like merged fingers or inconsistent text
Metadata Examination
- EXIF data analysis checking for camera and editing metadata
- Compression artifact patterns distinguishing real camera output from AI renders
Key Features
Detailed Detection Reports
Each detection generates a comprehensive report listing all analyzed indicators. The detector examines specific regions of the image (faces, hands, backgrounds, objects) and provides explanations for each finding.
