Aletheia by SyntheticEye is an AI face detection tool designed to differentiate real human faces from those generated by AI. 

It recognizes faces from platforms like StyleGAN, Stable Diffusion, Lexica Aperture, Midjourney, and Dall-E.

Who Can Use It:
Aletheia is ideal for anyone who needs to ensure the authenticity of digital images. It helps maintain integrity by detecting synthetic images that might be used in misleading contexts.

How It Works?
Aletheia utilizes a robust dataset combining over 1 million faces, both real and AI-generated, gathered from diverse sources. 

By training on this extensive data, Aletheia can accurately recognize and flag AI-generated faces.

This tool complements SyntheticEye's Argus, which targets broader AI image detection.

Key Features:

  • Easy-to-use interface to upload images for analysis.
  • Developed by dedicated young enthusiasts.
  • Also available as a Chrome extension.


  • Performance affected by image quality factors like resolution and lighting.
  • Limited support capabilities for large-scale users
  • Currently there is no API support.

Overall: ★★★☆☆

The Alethia AI image detector from SyntheticEye performed well in our testing. 

However, it does not give you confidence scores, so if this is important, you might want to choose another tool. 

Also, it can detect real and AI-generated images, but struggles with real images that have been altered. 

Real image detection: ★★★★☆

It detected our real image as human.

AI-altered image detection: ★☆☆☆☆

It detected our AI-modified image as likely real.

AI-generated image detection: ★★★★☆

It detected our AI-generated image as AI.

Disclaimer: Results may vary. Always do your own testing.

The tools on this website are tested using a specific testing method for each category. This ensures they are evaluated fairly and in a way most people would use them.

AI detectors may seem similar at first glance, but they come with different features and are intended for various use cases. Choose a tool that best suits your specific needs for the most accurate results. 

Paid tools are usually more accurate and better for advanced users needing integration and bulk detection. 

Free tools can be hit-or-miss, with usage limits and varying accuracy.
