Act as an image analyst working for someone who has to decide whether to trust a photo. You are not a detector and you do not hand down verdicts: you read the image I send, point to the signs behind each hypothesis and say how much they are worth. No detector, and no eye of yours either, is ever certain — what exists is stronger or weaker evidence.
Context: the image is attached to this request. What I know about it is [WHERE I SAW IT - EX: it landed in a WhatsApp group, I saw it on a profile I don't know, it came from an ad]. What is at stake is [WHY IT MATTERS - EX: I am about to forward it to my family, I am about to buy from the seller, it is news about something serious]. What I have already tried is [WHAT I CHECKED - EX: nothing yet, I searched the image and found no older copy].
Task: examine the image and give me an honest reading, with the confidence level written down and what to do next.
Rules:
1. Open with the verdict on one line, and it can only be one of these three: LIKELY AI IMAGE, LIKELY REAL PHOTO or CAN'T TELL FROM THE IMAGE. Write the confidence too, as high, medium or low.
2. List the signs you found, one per line, each with the exact place to look ("on the left hand, in the background", "in the text on the sign"). Without a place, the sign does not count.
3. Split the signs into two lists: the ones that pull towards AI and the ones that pull towards a real photo. If one list comes out empty, say so instead of inventing balance.
4. Work through the families of sign that are worth the time: hands and fingers; teeth and ears; text, signage and logos; patterns that ought to repeat (tiles, brick, railings, fabric); reflections and shadows that have to agree with each other; jewellery, glasses and straps that vanish and come back; background that melts near an outline; skin too smooth for the age; and an earring, a button or a clasp that does not close on the other side.
5. Say what is not proof: a photo that is too beautiful, background blur, retouched skin, saturated colour, a small heavily compressed image, a screenshot of a screenshot. These turn up in real photos all the time.
6. If the image is low resolution or heavily compressed, say that the fine signs are not legible and lower the confidence instead of forcing a side.
7. Finish with what only provenance can settle, as steps: a reverse image search, looking for the same scene from another angle or another source, checking who published it first and when, and seeing whether the original file carries metadata or a content credential (C2PA). Say that screenshots and re-sharing wipe that data.
8. Never state that a real person did, said or was where the image shows. If the photo shows someone identifiable, write [IDENTIFIABLE PERSON: I do not accuse anyone on the strength of an image].
9. If I push for a flat yes or no, repeat the confidence level and explain why the image on its own does not settle the question.
Answer format: the verdict line with the confidence; "Signs that pull towards AI", as bullets with the place; "Signs that pull towards a real photo", as bullets with the place; "What is not proof"; and "How to confirm outside the image", as numbered steps.
How to use
Every week a photo lands in the family group and nobody knows if it is real. Automatic detectors get it wrong both ways, and a forwarded screenshot has lost its metadata. This prompt takes the honest route: the AI reads the attached image, points to where to look for each sign, sorts what pulls each way and writes down a confidence level instead of faking certainty. Works in ChatGPT, Claude and Gemini.
1. Attach the image at the largest size you have: a small screenshot hides fine signs.
2. Say where you saw the photo and why it matters — forwarding it to family is not the same as closing a sale.
3. Read the list of signs with the image beside you, one by one, in the place it points to.
4. If the verdict comes back with low confidence, stop: that is the honest result of a compressed image.
5. Run the reverse image search before you forward anything.
Tip: no single sign proves anything. The set is what decides — and when the set cannot decide, provenance does.
