Joi AI's 28-day paid masturbation study makes health claims its self-reported data cannot support
↗
AI companion company Joi AI ran a small paid study on AI-guided sexual wellness and promoted broad claims about stress, focus, and addiction that its uncontrolled, self-reported design cannot validate.
A commercial AI companion service is marketing qualitative product research as evidence that its product improves mental health and reduces addictive cravings. Engineers and product teams building wellness-adjacent AI tools should note the gap between what a tiny self-selected study can show and what a company claims it proves. The study had no placebo condition, no objective measurements, and only six completers.

Joi AI paid ten participants $2,000 each for a 28-day study, but only six completed it and the design lacked placebo controls or objective cognitive tests.
The company reported a 25 percent stress reduction, 17 percent focus increase, and 44 percent decline in cravings, but found no significant satisfaction difference between AI-guided sessions and participants' preferred methods.
Neuroscientist Nicole Prause told WIRED that Joi's addiction language was a major overstatement, and sex-tech researcher Chloé Locatelli warned that personalised AI companions could become a crutch.
