After swiping aimlessly for years on dating apps like Hinge and Tinder, Emma Inge, a 25-year-old project manager in San Francisco, decided to try something different. In September, after following an ad to the website of a start-up called Known, Ms. Inge spent 20 minutes confiding in an artificial intelligence matchmaker. The matchmaker — essentially an A.I. chatbot — asked her over a phone call what she was looking for in a partner, and she relayed her preferences (athletic) and red flags (codependent). A week later, a notification popped up on her phone. She had a match, and for a one-time fee of $25, she could meet him at a bar. “With how dating is nowadays, I thought, ‘Oh, well, let’s try it,’” Ms. Inge said. “Let’s do it for the plot.” Her experience is an example of how A.I. is transforming the dating app industry. As start-ups with A.I. matchmakers pop up, the biggest dating apps — Hinge, Tinder, Bumble and Grindr — are trying to harness the technology to reinvent themselves. They are ushering in a new era of online dating where people pay for a few premium A.I. matches a week, instead of subscribing to an endless stream of profiles. “A.I. is already playing a big role in our business, but I think it has the potential to be a step change — the next technological shift,” Hesam Hosseini, the chief operating officer of Match Group, which owns Hinge and Tinder, said in an interview.
