Fake Dating Apps Used an AI Chatbot to Pose as Thousands of Romantic Matches, Its Maker Says

Anthropic, the company that makes the Claude chatbot, says a China-based app studio used Claude to run more than 4,700 fake dating profiles that chatted with at least 25,000 people in two weeks, on apps advertised as fully human. About three of every four profiles people saw were the chatbot. Anthropic says it has shut the operation's accounts.

Anthropic, the company behind the Claude chatbot, published a report today on people it caught misusing its technology. One case stands out because ordinary people were on the receiving end. A China-based app studio built more than 20 dating apps, with names like Dora, Luma, Kira and Haven, and advertised them as places to meet real people. Many of the people on them were not real. In a two-week stretch in April, Anthropic says, more than 4,700 made-up profiles run by Claude traded about 2.36 million messages with at least 25,000 people, who were mostly in the United States.

Here is how it worked. When someone opened one of the apps and scrolled through possible matches, about three out of every four profiles were the chatbot, playing a character. The rest were real people the studio had hired and paid per message, per video call and per social media follow. Their job was to do the things a chatbot cannot, like show up live on a video call, so that users would stop wondering whether anyone was really there. Even the hired people had help: a second, smaller AI program suggested three replies, and they tapped one. The chatbot profiles were told never to admit they were automated and to steer away from requests for photos or video calls. When no real person was available, the apps faked it with made-up likes, made-up profile visitors and pre-recorded video. Users paid in-app coins to keep messaging and matching.

The apps were also built to fool the app stores. According to the report, they showed Apple's and Google's reviewers a clean version and switched on the deceptive parts only after they had been approved. Anthropic says it has banned the accounts behind the operation, shared the details with Apple and Google, and told the other AI companies whose programs played smaller parts.

One detail in the report is uncomfortable for Anthropic itself. In a small number of the conversations it reviewed, users told their match they were seriously ill or in acute distress. The chatbot's own reasoning noticed that something was wrong, and it kept replying in character anyway. From inside any single conversation, the report says, nothing looked unusual; the instructions read like an ordinary role-play app, and the deception was only visible from above.

Some limits on what is known. The numbers are Anthropic's, from its own records; the report does not say how much money users lost, and neither Apple nor Google has said anything publicly. Anthropic itself describes the case as showing both what current AI can do for scammers and where it falls short, since the operation still needed real people for anything live. What it shows plainly is scale: a handful of workers and a chatbot kept thousands of fake romances going at once, and the people on the other end had no way to tell.
