Learn about your health inside out

Voice recording screening: We leverage machine learning to extrapolate voice patterns from your voice recording and identify signs of brain, mental and respiratory conditions to evaluate brain, lungs, and mental fitness.

‍Face video screening: We leverage machine learning to analyze blood vessel changes and blood molecule concentration based on light reflection patterns on your skin. This technology is called Photoplethysmography (PPG). With PPG, we can assess your cardiovascular and respiratory health. Finally, the assessment of your metabolic health is performed by analyzing the external features of your eyes (e.g. color of the sclera, pupil size, eye blood vessels concentration).

Yes, research showed that detecting cardiovascular, mental, pulmonary, and brain biomarkers from face video and voice recording can reach an accuracy higher than 90%. In addition, Purovitalis leverage partners’ technologies that already got medical certifications or are close to it. Finally, we are also working on novel technologies in-house (e.g. Detecting HbA1c from external eye images). 

Face videos can be used to detect vital signs and blood biomarkers and assess a person’s health status and risk of developing diseases. The underlying technology is called Photoplethysmography (PPG). It leverages RGB light reflection patterns from a person’s face to detect changes in the skin and blood vessels. The technology can detect blood pressure, heart rate, heart rate variability, respiratory rate, stress levels, oxygen saturation, and, in the near future, even cholesterol and sugar levels (glycated hemoglobin). This information can be used to assess cardiovascular health (e.g. arrhythmias risk, stroke risk, hypertension risk, diabetes risk), respiratory health (e.g. sleep apnea) and mental health (e.g. stress and anxiety levels). The accuracy varies depending on the specific biomarker and the length of the face video.

Voice recordings contain useful information that can be used to detect diseases. Thanks to state-of-the-art machine-learning algorithms, it is possible to extrapolate and interpret hidden voice patterns (aka voice biomarkers) associated with multiple health conditions. The most prominent applications of voice biomarkers are the early detection of brain disorders (Parkinson, Alzheimer’s, Dementia), Depression, other mental disorders, and respiratory conditions (Asthma, COPD, and even COVID). The accuracy varies depending on the disease. However, the technology already showed relevant results, achieving accuracy levels higher than 90%.

Yes, our partner YOUTH co-founder and Chief Medical Officer is a medical doctor and researcher at UCSF. They also have a team of medical consultants and a prestigious board of medical advisors from the best hospitals and academic institutions in the world. Additionally, Purovitalis stipulates partnerships with doctors and longevity clinics around the world.

We can ensure the following:
– All data is encrypted.
– We do not store face videos.
– All your user data is deleted as soon as the Purovitalis AURA ai account is canceled.
