Microsoft unintentionally built a viral sensation a few weeks back when it demoed a site it had built that guessed your age using Azure services on stage at its BUILD developer event in San Francisco.

The tool went far and wide, making it to almost everyone I know and was all over Facebook, mostly because it was hilariously bad at actually guessing your age correctly. Before long, everyone was abusing it.

Now, Microsoft’s done it again, with a new site that guesses if you’re twins or not based on two photos. You hand over a photo of yourself and someone else, then the site spits out a percentage of how alike you look.

Apparently I don’t look much like Ron Weasley at only 32% similarity, but I’m very similar to Ed Sheeran at 90%. That basically means I’m famous, right?

For real world twins, like Cameron and Tyler Winkelvoss, the site says they’re 100 percent twins. How did it go for you?
