A friend once showed me a message her match had sent, three neat paragraphs about how her hometown's light must have shaped her, and it was lovely, and it was not his. She found that out over dinner, when the person across the table struggled to finish a sentence about the weather. She was not angry about the words. She was angry about the version of him she had already agreed to meet.
That gap between the profile and the person now has a name in the research, and a number attached to it. A 2026 paper presented at the CHI Conference on Human Factors in Computing Systems, by Meryem Barkallah and Douglas Zytko, surveyed 113 online daters across 15 countries who had used AI-generated text or photos in their own self-presentation, or had a match use it on them. Its title is a direct quote from one of them: "I Wanted Them to Think That I Wrote That." The finding underneath the wit is plainer and harder: this kind of help is common, and it is, in the researchers' words, "seldom disclosed to meeting partners to avoid romantic rejection."
Some of what the study describes is not really fabrication. Several daters said AI helped them gather scattered, true facts about themselves, their hobbies, their actual plans, into a bio that read more like them than their own draft had. That is closer to a good editor than a disguise. But the researchers also found a colder use: bios and messages built with no relevance to the person's real traits at all, sometimes tuned to manufacture a sense of unique chemistry with one specific match rather than a generic, appealing stranger. When participants explained why they kept quiet about either kind of help, the reasoning was almost always the same. Saying so felt riskier than not saying so. Rejection was the thing they were managing, not honesty.
The researchers do not treat that as a small etiquette lapse. They argue that because informed consent is what separates sex from sexual assault, an undisclosed, AI-shaped persona can leave a partner's consent misinformed once things turn physical, the same legal territory long occupied by hidden STI status or secretly removed condoms, sometimes called rape by deception. That is the researchers' frame, not a verdict, and it is a serious jump from a witty opening line to a courtroom concept. But it is the right instinct pointed at the right target: the harm was never the machine. It is what a person chose not to tell you before you decided whether to trust them.
Dating coaches have split over the milder version of this problem, and a February 2026 survey of 1,008 US singles by the matchmaking service Arrows shows why: shown profiles blind, people preferred AI-written bios over human ones by 36 percent to 24 percent, yet 58 percent call AI use in a profile or a message "digital catfishing" once they know about it. New York dating coach Erika Ettin tells clients to put the chatbot down, because, as she told TODAY.com, it "stifles your authentic self. It is not you, and you can't bring AI on your date." She is not wrong, but the fix she is really describing is not a ban. It is a disclosure.
You do not owe a stranger your rough draft. You owe them the chance to meet the person who is actually going to show up. Say who helped, before the polish becomes the whole of what they liked.
