Oura Tests Its First In-House AI Model for Women's Health Questions in Oura Advisor
The ring maker's own large language model pairs clinician-reviewed sources with members' sleep, cycle and pregnancy data, and is opt-in through Oura Labs for now.

Key points
- Oura has begun testing its first proprietary large language model, built for women's health questions and delivered through its Oura Advisor chat feature.
- The model draws on sources reviewed by Oura's in-house clinicians and on members' biometric trends across sleep, activity, cycle and pregnancy data, and stress.
- It is available only to members who opt in to Oura Labs; Oura said wider availability depends on test results and feedback.
Oura has started testing its first proprietary large language model, a model built for women's health questions that runs inside its Oura Advisor chat feature, FemTech Insider reported on February 24. The model is rolling out to members who opt in to Oura Labs, the company's test program, rather than to all users.
According to CMOtech UK, the model combines clinician-curated medical knowledge with data from the Oura Ring and app, and covers the reproductive health spectrum from early menstrual cycles through menopause.
How the model answers
When a member asks Advisor a women's health question, the system draws on a curated base of research and knowledge sources reviewed by Oura's in-house clinicians and women's health experts, and analyses biometric signals and long-term trends across sleep, activity, cycle and pregnancy data, and stress, CMOtech reported. Oura said it tuned responses to be non-dismissive and emotionally supportive.
The company said it built the model with its own clinical and technical teams using knowledge-graph technology from webAI, and that the model is hosted on Oura-controlled infrastructure. FemTech Insider reported that conversations are never sold, shared or used to train third-party AI systems.
“This custom model is a fundamental shift in how we responsibly deploy AI in health to meet the needs of our members,” said Ricky Bloomfield, Oura's chief medical officer.
Chris Curry, Oura's clinical director of women's health and a board-certified OB/GYN, said the aim is preparation for clinical visits. If a member asks why a cycle has suddenly become irregular, Advisor can walk them through “what's typical, what their data may be showing, and what would be most helpful to surface in conversations with their provider,” Curry said.
Testing first
Oura Labs is opt-in, members can leave at any time, and features tested there can be refined, removed or folded into the core app, CMOtech reported. Further development and wider availability of the women's health model will depend on results from the Labs program and member feedback, the outlet said.
FemTech Insider noted that Oura said last year that women make up the majority of its user base. The company cited survey findings that most U.S. adults look up health symptoms online and that many see AI-generated answers in their results. Oura did not publish accuracy or evaluation data for the model.
