What does PSL Range measure?

It estimates how an adult face appears in submitted photos on the 1.0–8.0 PSL convention. The output reflects the images and their conditions, not a person's value.

Should I upload one photo or several?

One clear image gives a fast estimate. Supplying two to five images lets the tool compare different conditions and return a more stable interval.

Is PSL Range free to use?

Yes. Both the quick result and the multi-image range are available without registration, a paywall, or payment.

Why can the result vary across photos?

Lighting, camera angle, facial expression, image quality, and how clearly the face is visible can all affect the reading. Comparing several images helps limit this bias.

What appears in a multi-photo result?

The report contains a stable interval, individual photo results, the strongest image, and the main condition associated with variation.

Does PSL Range keep uploaded photos?

The site says original images are handled only to produce the result. They are not retained, used to train models, or displayed publicly.

May I analyze another person's photo?

Only submit an adult image you own or have permission to use. The site does not allow rating people without consent.

What is PSL Range?

PSL Range is a free web tool that applies AI vision analysis to adult face photos and returns an estimate on the 1.0–8.0 PSL scale. Begin with one image for a quick result, or compare as many as five to see a steadier range, individual results, the strongest photo, and the factor causing the largest swing.
