A new website aims to answer whether two people look alike or not.

Twins Or Not simply requires a user to upload two photos to the site and it then gives a "twin score" rating the resemblance of the two people, Yahoo Tech reported.

Twins or Not is similar to the recent website how-old.net. How-old.net tried to predict the age of people who would submit their photos to the website. Twins Or Not uses Microsoft's Machine Learning tools, which allowed for the website to be created quickly and easily.

A software engineer at Microsoft, Matt Velloso, was able to develop the site in just four hours from his hotel room in the Czech Republic.

"Yes, it is that simple. We can create amazing, fun and useful sites and applications one after another, as many as we want," he wrote in a blog post.

Twins Or Not will give Microsoft's new cloud API a ton of exposure. How-old.net became a social media hit, even though many of its age predictions were inaccurate. Velloso said it was used by "millions of people."

It is unpredictable if Twins Or Not will have the same level of success and popularity as How-old.net, but "twin scores" seem like the perfect item to be posted on Facebook or Twitter.

Users can upload pictures of themselves and a friend or even a stranger they think has a strong resemblance to them. Once uploaded, Twins Or Not will assign a "twin score" to the two images. A rating of 100 percent would mean an exact identical twin.

Twins Or Not promises not to keep any images that is shared on the site. As of Friday afternoon, almost 900 people have shared the website with their friends on Facebook. Visitors to the website have already tried comparing celebrities and politicians on the website.
