PimEyes How it works

Think your partner is cheating? Check where their photos appear

If you suspect a partner is on dating sites or has hidden social profiles, a face search can show where their photos appear on the public web. PimEyes takes one photo and lists matching faces with the page each was found on. That can turn a vague worry into something concrete you can talk about, or put it to rest.

What a face search can find

What it can't find

Name-based finders vs face search

Dating-profile finders, often called "cheater busters", usually search one dating service by first name, age and location. A face search starts from a photo instead, so it works when the profile uses a different name, and it covers pages across the web rather than one service.

Step by step

  1. Pick a recent, clear photo of your partner's face, ideally one they use online.
  2. Run a Deep Search in PimEyes.
  3. Open each strong match and look at the date, the site and the name used.
  4. Screenshot what you find before it changes.

Before you confront anyone

A match is evidence that a photo is online, not proof of cheating. Old profiles, stolen photos and lookalikes are common. Talk calmly, show what you found and listen. If you feel unsafe in your relationship, contact a local support service first.

Common questions

How can I find out if my partner is on dating sites?

Run a face search with a clear photo of them. If their photos appear on public dating-profile pages or galleries, the matches will show the pages. Profiles that aren't public on the web may not be visible.

Can a face search find hidden Instagram or Facebook accounts?

It can find public profiles that use the same face, even under a different name. It can't see private accounts.

Is it legal to search my partner's photo?

Searching public pages is generally legal. Don't access their accounts or devices without permission; that is illegal in many places.
