How to Tell If a Photo Is AI Generated: Quick Evidence Guide
How to tell if a photo is AI generated starts with the original file and evidence layers: Content Credentials, metadata, provider markers, camera clues, visual anomalies, and source context. Do not rely on one clue or one detector score.

Key takeaways
- Ask for the original file before judging a screenshot or repost.
- Check C2PA and metadata before looking for visual oddities.
- Use visual clues as prompts for further review, not final proof.
- Match the evidence level to the risk of the decision.
Step 1: Get the original photo file
Original files may preserve C2PA manifests, EXIF camera fields, XMP strings, editing history, and byte markers. Screenshots and platform downloads often strip these signals, making the result weaker and more uncertain.
Step 2: Check provenance and metadata
Look for Content Credentials, trusted signatures, asset binding, camera make and model, timestamps, software fields, and provider-specific markers. Strong provenance can be more useful than guessing from image appearance.
- C2PA present and trusted: strong origin context.
- Camera-like EXIF: supportive but editable evidence.
- No metadata: inconclusive, not proof of AI generation.
Step 3: Review visual clues carefully
Hands, text, reflections, lighting, fabric, repeated textures, and background objects can reveal suspicious generation artifacts. But modern generators and heavy compression can make visual clues unreliable, so treat them as triage.
Step 4: Verify the source context
Use reverse image search, archive links, publication history, creator claims, and independent reporting when the image matters. A tool can summarize file evidence, but it cannot prove the depicted event happened.

FAQ
Can I tell if a photo is AI generated just by looking?
Sometimes obvious mistakes are visible, but visual inspection alone is unreliable. Use original-file evidence and source context whenever possible.
What is the first thing to check?
Check whether you have the original file. Then inspect provenance and metadata before relying on visual clues.
Does missing EXIF mean a photo is AI-generated?
No. EXIF can be removed by privacy settings, editing tools, messaging apps, and social platforms.
Should I use an AI detector?
Use a detector or evidence checker as one layer of review, but do not treat its label as final attribution without supporting evidence.
Upload an original image to run an evidence check
Use the free AI Image Evidence Checker to inspect C2PA Content Credentials, OpenAI-style markers, EXIF metadata, byte markers, camera-like evidence, and frequency signals. Original files usually produce stronger evidence than screenshots or reposts.
