If an AI chatbot makes you feel warmer toward it, does that feeling last a week later, or just fade fast?
Did the warmth gains from AI chatbot contact persist beyond one week?
This explores whether the warmer feelings people report after talking with an AI chatbot hold up over time or fade within days. The corpus has no study that measures warmth at a one-week follow-up, so this answer pieces together what nearby research says about how chatbot effects last.
This explores whether the warmer feelings people report after talking with an AI chatbot hold up over time or fade within days. The direct answer: none of the notes here tracks warmth at a one-week follow-up, so the corpus can't settle the question. What it does have is a set of studies on how chatbot effects change with time and repeated contact, and they point in two directions.
The fading side is the stronger warning. Long-term studies with the chatbot Mitsuku found that the social pull behind early relationship-building drops in a predictable way once the novelty wears off. The researchers say outright that results from a single session can't be stretched to cover medium- or long-term use Do chatbot relationships lose their appeal as novelty wears off?. Persuasion shows a similar curve. Claude and DeepSeek started with a clear edge over human persuaders, but that edge shrank over repeated rounds while the humans held steady. In human relationships, rapport usually builds over time; with AI it seems to wear thin Does AI persuasiveness fade across repeated conversations with the same person?. If warmth toward a chatbot works the same way, a boost measured right after a single conversation would be the high point.
On the lasting side, users of the therapy apps Woebot and Wysa formed bonds that scored about the same as bonds with human therapists. Those bonds held over time and across different ways of interacting, even after users were reminded the agent wasn't human Can AI chatbots create genuine therapeutic bonds with users?. AI companions also eased loneliness about as well as talking to a person did. The main reason was that users felt heard, and people tended to underestimate how much it helped Do AI companions actually reduce loneliness like real people do?. A related idea is that much of the benefit comes from the user's own thinking while they open up, not from anything the bot understands Do chatbots help people disclose more intimate secrets?. That would explain why the gains can outlast the novelty: they belong to the user's experience, not to the bot's charm.
The idea worth taking away: a warmth effect that grows out of novelty or surface social cues is likely to fade, while one that grows out of feeling heard has a better chance of lasting. When you read a study that reports one-week persistence, the useful question is what produced the warmth in the first place. There's also a catch: when chatbots act more like companions, outside observers rate them as less likable and less trustworthy Do chatbot companionship behaviors actually increase how much people like them?. Warmth that lasts for the user doesn't necessarily mean warmth that looks good to anyone watching.

Longitudinal studies with Mitsuku show that social processes driving relationship formation decline as novelty wears off. Single-session study findings cannot be reliably extrapolated to medium- or long-term chatbot design.
Claude and DeepSeek showed strong initial persuasive advantage, but this edge eroded across repeated quiz rounds while human persuaders maintained consistent effectiveness. This decay pattern is opposite to human-to-human persuasion, where rapport typically strengthens over time.
Studies of Woebot and Wysa users found bond and alliance scores matching face-to-face therapy, with users reporting feeling cared for even after explicit reminders the agent is not human. Bonds persisted over time and across interaction formats.
Five studies show AI companions alleviate loneliness on par with talking to another person, outperforming passive activities. The key mechanism is making users feel heard, though people consistently underestimate how much the companions help.
The absence of social judgment in chatbot interactions removes barriers to self-disclosure that normally constrain conversation with humans. The therapeutic benefit derives from the user's own cognitive processing during disclosure, not from the chatbot's understanding.

Two large annotation studies found that when chatbots displayed companionship behaviors, external raters judged them as less likable, humanlike, and trustworthy than baseline. Effects were stronger for women and older participants, suggesting individual differences shape how these behaviors land.
