Journalists and fact-checkers
Use detectors only as a lead. Confirm with reverse image search, geolocation, source history, archive pages and direct verification from the original publisher.
Free tools
Free AI image detector websites to try before you trust a picture.
Use these tools for a quick second opinion on AI-generated pictures, deepfakes, product photos, social posts and suspicious profile images. Always check upload limits and privacy terms before using sensitive files.
Tool directory
Free or free-tier AI picture detector sites.
This list focuses on websites with public demos, guest checks or free accounts. Availability changes, so treat “free” as a starting point and verify the current limit before relying on a tool.
Free demo
Sightengine
Useful for AI image detection, deepfake checks and broader media moderation. Good fit if you also need API access later. Check account credits and upload policy before sending sensitive files.
Free toolsAI or Not
Checks images and other media types with a simple upload interface. Useful as a second-opinion detector when you want a fast AI/not-AI style result.
Guest checksWasItAI
Focused on whether an uploaded image appears AI-generated. Helpful for casual checks, screenshots and suspicious social images, though original files are better than screenshots.
Free tierIs It AI?
Offers image upload or URL analysis, confidence-style results and generator-oriented claims. Useful when you want a detector that explains likely method as well as verdict.
Free checkerBrandWell
Provides file upload or image URL checking for AI probability. Good for quick checks, especially when you have a web image URL instead of a local file.
Free accessIlluminarty
Offers image-origin review features. Best used after reviewing its account requirements, upload terms and privacy policy.
How to compare
Do not rank tools only by the highest confidence score.
A detector with a dramatic 99% answer may still be wrong. Compare how the tool explains the result, whether it supports the image type, and whether the file you uploaded is close to the original.
| What to compare | Why it matters | Better choice |
|---|---|---|
| Upload type | Some tools handle files only; others accept image URLs or video. | Use a tool that supports your original format. |
| Free limit | Guest checks, free credits and monthly limits vary. | Use free tools for triage, paid/API tools for volume. |
| Result detail | A bare label is less useful than confidence, method and caveats. | Prefer tools that explain uncertainty. |
| Privacy terms | Uploaded images can contain faces, IDs, addresses or client material. | Avoid uploading sensitive images unless terms allow it. |
| Generator coverage | Tools may perform differently on Midjourney, DALL-E, Flux, Firefly, Stable Diffusion or newer models. | Compare multiple detectors when stakes are high. |
Use cases
Which detector workflow fits your situation?
The right tool depends on why you are checking the image.
Students and educators
Detector results should not be the only basis for an accusation. Keep drafts, prompts, source images, project files and process notes.
Marketplaces and buyers
Check product photos for repeated backgrounds, impossible details, mismatched variants and whether the seller has real review photos from buyers.
Profile and dating images
Use reverse search, video calls, account history and consistency across images. A detector score alone cannot prove identity.
Evidence and disputes
Preserve originals and chain of custody. Use qualified forensic review instead of relying on a public upload result.
Artists and publishers
Check rights, licensing, disclosure and whether the final asset is stock, AI-assisted, generated from scratch or heavily edited.
