A new tool for Facebook can scan your posts to analyze your online personality, letting you know if your posts actually tell the world who you are.

Coming from the startup Five Labs, the "quiz" of sorts scans your statuses and comments to compare them to five personality traits: extraversion, openness, neuroticism, conscientiousness, and agreeableness, The Christian Science Monitor reported.

According to Five Labs founder Nikita Bier, the app has more than 100 million users so far. The tool is intended to make users more aware of what they post, Bier said.

"Social networks have become corrupted, more like television," he said, according to the CS Monitor. "We wanted to get a feel for just how far Facebook has drifted away from actually being a social network. It's lost that town-square feel it once had before it was opened up to people outside a college campus environ."

Available on the Five Labs website, the tool asks for permission to access a Facebook profile, then analyzes only the user's words in statuses, photo shares and comments. Afterward, the profile is scored for the "Big Five" personality traits and given a list of key words.

People can only use the tool once, even if they don't recognize themselves in the results, something that Bier blames on their online persona.

"You can't alter the results because you can only do the analysis one time," said Bier, according to the CS Monitor. "We would never be able to handle the volume of people retrying. That's actually one of the most interesting results of this lab: people don't recognize themselves and what they've become on social media."

His ultimate goal for the new tool is that it will help people to recognize the ways they change their personalities on social media and become more themselves instead.  

"We are creating a kind of restaurant or café kind of meeting place where people can be real with each other again," said Bier. "Instead of tailoring your identity as we seem to be doing on Facebook we can be ourselves again."
