AI or Not is a freemium web tool that analyzes images to determine whether they were created by artificial intelligence or a human. The free tier covers 20 image checks a month; Pro is $5/month, with credits that also unlock video, voice, and music detection.
- Style detection: recognizes AI-generated content across both photorealistic and artistic styles.
- Watermark friendly: maintains accuracy even when images contain watermarks.
- Model identification: tells you which AI system (Midjourney, Stable Diffusion, and newer generators) created the image.
The tool works impressively well with high-quality images but often struggles with compressed files and sophisticated AI fakes. We find its ability to identify artistic AI styles particularly valuable when verifying the authenticity of digital content.
