Everyone is using a new feature in one of Google's little-known apps.

Over the past weekend, if you were on Twitter or Facebook at all, you might've noticed friends sharing comparisons of their selfies to famous pieces of art. That's because Google's Arts and Culture app, which lets you learn more about art, national monuments, and more, now helps you to see if you look like the Mona Lisa or Picasso's Dora Maar.

While the app updated with this tool in December, for whatever reason, it's just now blowing up. Google's app became the most-downloaded free app on both the Apple App Store and Google Play Store, claiming the No. 1 spot in the US on 13 January, according to the app metrics site AppAnnie.

Here's what you need to know about it.

Google Arts and Culture is a free mobile app for iOS and Android devices as well as Cardboard and Daydream devices. It has been around for a couple years, allowing you to browse collections curated by experts from the most famous museums. You can use it to see photos, videos, manuscripts, and art on every screen and in VR.

The Google Arts and Culture app now lets you take a selfie and discover if your portrait is in a museum, though the feature is only available in select locations (like the US). You essentially take a selfie, and the app finds art with subjects that - should - properly match your face. It's goofy but also great fun. It's also very shareable.

The app uses computer-vision technology and machine learning to examine your face and compare it with thousands of pieces of art that are shared with Google by museums and other institutions. Google has told some news outlets that the feature is experimental, so don't take things too personally if it matches you to something hideous.

  1. Open the Google Arts and Culture app.
  2. Scroll down to the "Is your portrait in a museum?" section.
  3. Tap on the Get Started button.
  4. Agree to let Google analyse your photo. It won’t store the image.
  5. Grant permission to your camera and photos.
  6. Take a selfie and allow the app will scan the image.
  7. Swipe through the artwork and notice each piece's percentage match.
  8. Select the Share button at the bottom to share a match on social media.
