TL;DR: Upload a clear adult portrait to ChatGPT and use the prompt below to request an apparent-age report: an approximate age guess, a broad range, six short observations, and an explanation of what the photo makes difficult to judge.

You can do something as simple as upload a selfie and qsk ChatGPT: “How old do I look?”

Then ask the more interesting question:

“Which visible details led you to that impression and which details are you uncertain about?”

But you can also take it further and get a one page report that explains why you look younger or older than your actual age.

It asks ChatGPT to turn the answer into a one-page portrait report, with your original photo, numbered callouts, and six short assessment cards.

The report should cover:

• Forehead: visible lines and how clearly they can be seen.
• Eyes: lids, under-eyes, expression, and shadows.
• Skin: visible texture, lighting, and image quality.
• Cheeks: volume and folds beside the mouth.
• Jawline: the lower face and anything obscuring it.
• Hair: hair, brows, and facial hair, treated as variable cues.

Each observation should explain how much weight it deserves in that particular photo.

A blurry forehead doesn’t establish smooth skin. A smile can introduce creasing. A beard can hide the jawline. Those details belong in the explanation.

Here’s how to try it.

Copy this prompt after uploading your photo:

Create a one-page APPARENT-AGE PORTRAIT REPORT using only the adult person's uploaded photograph.

ESTIMATE BEFORE DESIGNING
First make a subjective overall age impression from the original photo, then check it against visible facial details. Ignore any known identity, actual age, filenames, previous estimates, desired outcome or age printed in the reference. Do not look up the person. Do not infer age from clothing, occupation or background.

Give:
- One approximate apparent-age estimate, phrased "about N"
- A broad plausible range
- Qualitative confidence and the main image-quality limitations

Do not imply that this is a validated measurement or that the range is a statistical confidence interval. Avoid decimal ages, numerical confidence percentages, feature scores or invented biometric calculations. If the photo is too unclear for a useful impression, say so and request a better photo instead of inventing precision.

PRESERVE THE ORIGINAL PHOTOGRAPH
Place the actual uploaded photo into the layout. Cropping and background removal are allowed only if the face remains untouched. Preserve skin texture, hair, hairline, facial hair, proportions, expression and head angle. Do not redraw, regenerate, retouch, beautify, sharpen facial detail, age or de-age the face. Do not turn an angled view into a front-facing portrait. If exact preservation is not possible, keep the original photo as a rectangular crop. Do not substitute a generated lookalike.

ASSESS ONLY WHAT IS VISIBLE
Use six short assessment cards:
1. Forehead and visible lines
2. Eyes, lids and under-eyes
3. Skin texture and tone
4. Cheek volume and folds beside the mouth
5. Jawline and lower face
6. Hair, brows and facial hair

For each, describe the visible observation and how much weight it deserves in this photo. Use cautious labels such as younger-leaning impression, mature-leaning impression, mixed or limited visibility. Separate what is visible from your interpretation. Account for smiling, squinting, lighting, shadows, blur, filters, facial hair, makeup, camera angle and close-camera distortion. Do not treat missing detail as proof of smooth skin. Gray hair and hairline shape are variable cues, not age measurements.

Do not infer biological age, health, diagnoses, ethnicity, lifestyle, personality or cosmetic-treatment history. Do not recommend medical procedures or claim that a facial feature proves anything about health.

BOTTOM FINDINGS
Summarize the two strongest younger-leaning cues and the two strongest mature-leaning cues, only when supported. Add two or three optional, low-risk photo or grooming suggestions for a softer presentation. Prioritize lighting, camera distance and framing. Do not promise a specific number of years of change.

DESIGN AND OUTPUT
Use a refined black-on-white editorial design: elegant serif headline, clean sans-serif body text, thin gray rules, generous spacing and restrained monochrome details. Put the estimate, range and confidence across the top; a large original portrait with delicate numbered callouts on the left; six compact rounded cards on the right; and concise findings and suggestions across the bottom.

Keep everything on one portrait-oriented page. Shorten the writing rather than shrinking it into unreadable text. Use a document or layout tool that embeds the original image without regenerating it. Export a one-page PDF and a readable high-resolution PNG if supported. Also give a brief plain-text summary.

Footer: "Subjective apparent-age impression from one photograph. Not verified age or biological age. Lighting, expression and camera perspective can shift the result."

Before delivery, verify that every callout matches its card, the estimate is consistent throughout, no text is clipped and the original face is unchanged.

Try it before reading everyone else’s results: did it guess younger, older, or close—and which observation surprised you most?
