Microsoft’s new website could be as viral as its age-guessing tool

A month after Microsoft’s “How Old Do I Look?” website went viral, one of the company’s developers has released a similarly fun tool called “Twins or Not?” which may or may not prove to be just as popular. Whereas the first tool tried to guess a person’s age based on a photo of them, oftentimes with hilarious results, this new tool rates different people on how similar in appearance they are. 

A Microsoft website called “How Old Do I Look?” went viral last month, mostly because its attempts to guess peoples’ ages from photographs was sometimes so wildly off base that people immediately began sharing their hilarious results (as well as results from uploaded pics of celebrities, animated characters, and inanimate objects). Now, a Microsoft developer has released another tool, based on the same machine-learning algorithms, that rates how similar or different any two people look. “Twins or Not?,” created by Microsoft developer Mat Velloso, asks visitors to upload two photos, and then ranks their facial similarity as a percentage, from 0% to 100%. I uploaded photos of Pope Francis and the High Sparrow, a religious leader from Game of Thrones (played by actor Jonathan Pryce), and got the result, “Twin score: 90%, you two are definitely related.”
