The smart ring maker is deepening its push into women’s health with a clinician-reviewed LLM offering personalized insights spanning menstrual health, fertility and menopause
Oura is expanding its artificial intelligence strategy with the launch of its first proprietary large language model built specifically for women’s health. The model, now rolling out for testing inside Oura Labs, pairs clinician-curated medical knowledge with members’ longitudinal biometric data.
Rather than relying solely on general-purpose AI systems, the smart ring maker designed the model around women’s physiology and life stages, supporting questions across the reproductive spectrum, from early menstrual cycles to perimenopause and menopause.
The system draws from medical standards and research reviewed by the company’s in-house team of board-certified clinicians and women’s health experts, while simultaneously analyzing relevant biometric signals, including sleep trends, stress, activity patterns, cycle data and pregnancy insights.
When a member asks a women’s health question, Advisor references its curated body of research while analyzing that individual’s biometric history to contextualize the response. The model is intentionally tuned to deliver responses that are clear, supportive and non-dismissive.
“This custom model is a fundamental shift in how we responsibly deploy AI in health to meet the needs of our members,” said Oura chief medical officer Dr. Ricky Bloomfield. “Women’s health is too complex — and too often overlooked — to rely on one-size-fits-all systems.”
The announcement builds on Oura’s growing investment in women’s health research and product development.
The company recently expanded its women’s health platform with the rollout of dedicated pregnancy and perimenopause features designed to provide more nuanced biometric visibility across major hormonal transitions.
The product expansion has been complemented by Oura’s research initiatives, including a large-scale pregnancy study analyzing physiological changes across more than 10,000 members, mapping shifts in resting heart rate, body temperature, sleep and activity throughout gestation.
The women’s health AI model will initially live inside Oura Labs, the company’s opt-in experimental environment. Oura emphasized that the model is hosted entirely on company-controlled infrastructure, and that user conversations are not sold, shared or used to train third-party AI systems. Participation remains optional, with members able to opt out at any time.
