What is an AI image detector?
An AI image detector is a tool that analyzes a photo or image and estimates whether it was created or heavily altered by generative AI — tools like ChatGPT's image generator, Midjourney, DALL-E, Stable Diffusion, or Google's Gemini/Imagen — versus captured by a real camera. Detectors work by looking for statistical fingerprints that generative models leave behind: unnatural noise patterns, missing or inconsistent camera metadata, texture irregularities, and compression artifacts that don't match how real cameras and editing pipelines behave.
No detector — including Pixoraid — can promise 100% accuracy on every image. The honest goal is a well-calibrated probability and clear evidence, so a human can make the final call with context a machine doesn't have.
How Pixoraid's detector works
Pixoraid Detect combines several independent signal sources rather than relying on a single check:
- Metadata / EXIF analysis — checks for camera make, model, and capture data that generative tools don't produce.
- Noise and texture forensics — real camera sensors leave characteristic noise; generated images often don't.
- Compression artifact analysis — looks at how the image has been re-encoded and resaved.
- Edge density and face-region analysis — generative models sometimes render edges, skin, and eyes with subtle irregularities.
- A trained detection model — scores the combined signals into a calibrated AI probability.
The result is a verdict — Real, AI-generated, or Uncertain — with a confidence level and a plain-language evidence summary, not just a percentage.
Why "uncertain" is a feature, not a failure
Many detectors are tuned to always output a confident-sounding answer, even when the evidence is thin. Pixoraid deliberately returns Uncertainwhen the signals are mixed or the image has been heavily compressed, screenshotted, or re-encoded — because a wrong confident answer is worse than an honest "this needs a human look."

Who uses an AI image detector
- Journalists and newsrooms verifying user-submitted photos before publishing
- Content moderation teams screening uploads at scale
- Marketplace and trust & safety teams checking listing photos
- Schools and universities reviewing submitted images
- Creators and photographers proving a photo is genuinely theirs
- Developers embedding detection into their own apps via the Pixoraid API

Is Pixoraid's AI image detector free?
Yes — the free plan includes 5 image checks per month with a full verdict, probability score, and evidence summary. Paid plans raise the monthly limit for creators, teams, and API users.
How accurate is AI image detection?
Accuracy varies by image type, generator, and how much an image has been compressed or edited after generation. Pixoraid reports a confidence level with every result and returns 'uncertain' instead of guessing when evidence is weak — no detector should be treated as courtroom-grade proof on its own.
Can it detect images from ChatGPT, Midjourney, and DALL-E?
Yes, Pixoraid checks for generation artifacts common across major generators including ChatGPT's image tool, Midjourney, DALL-E, Nano Banana (Google Gemini), and Stable Diffusion. See our dedicated ChatGPT, Midjourney, Nano Banana, and DALL-E detector pages for tool-specific notes.
Does a missing EXIF/metadata mean an image is AI-generated?
No. Screenshots, downloaded images, and photos shared through WhatsApp, Instagram, or other apps routinely strip metadata. Pixoraid treats missing metadata as one signal among several, never as proof by itself.
Can I use this detector through an API?
Yes — the Pixoraid Detect API accepts an image file and returns a verdict, confidence level, evidence summary, and report URL. See the API documentation for the full request/response format.
