Verdict
AI or Not ranks #3 among tested AI detectors with an overall accuracy of 75.5% across 98 images. It performs strongest against Flux Pro v1.1 images (100% detection rate) but struggles with Hunyuan Image 3.0 content (only 50% detected). With a 21.5% false positive rate, it frequently misidentifies real photos as AI-generated.

Benchmark Methodology
AI or Not was evaluated on a curated dataset of 98 images across 17 AI image generators and 3 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 AI or Not?
AI or Not is a dedicated AI image detection service that focuses exclusively on answering one question: was this image created by artificial intelligence or captured by a real camera? The platform provides a simple, focused tool for verifying image authenticity without the complexity of full content moderation suites.
Launched as AI-generated images became increasingly realistic, AI or Not has built a reputation for straightforward, accessible detection that anyone can use.
