Infermedica vs Ubie (2026)
Both build symptom based triage that tells a patient what level of care to seek, and they differ in where they are regulated. Infermedica, from Wrocław, Poland, reasons over a physician curated knowledge base of more than 1,800 symptoms, 900 conditions and 340 risk factors with probabilistic models, and sells triage, intake and follow up to health systems, payers and insurers. It holds EU certification as a medical device, states a US position under FDA enforcement discretion, and publishes a five level triage scale. Ubie, from Japan, runs a free consumer symptom checker covering about 1,000 diseases in a three minute questionnaire, and sells Smart Support to practices. Choose Infermedica to embed regulated triage in your own service; choose Ubie for a free consumer checker.

Infermedica, based in Wrocław, Poland, builds clinical triage that takes a patient from an undifferentiated symptom to a recommended level of care. Its inference engine, which the company describes as probabilistic models built on modified Bayesian networks and machine learning methods, reasons over a physician curated Medical Knowledge Base of more than 1,800 symptoms, 900 conditions and 340 risk factors, choosing each next question from the answers so far and ending with the most probable causes and a five level care recommendation from self care to ambulance.

Japanese health technology company with two AI products.

Questions buyers ask
How do Infermedica and Ubie work with the EHR?
The Triage module is listed in Epic's App Orchard to add symptom checking to MyChart, and the Intake module is integrated with ProAssist, with other record systems reached through the Infermedica API. Intake sends a structured pre-visit summary and a list of possible conditions to the physician, and Conversational Triage supports pre-fill from patient records and maps findings to ICD-10 and SNOMED.
With Ubie, the consumer checker does not integrate with records: patients take a report or doctor's note to their clinician. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.
Which settings and specialties do Infermedica and Ubie cover?
In Infermedica's case, the company reports use in more than 30 countries and 26 languages and more than 27 million checkups. Validation covers part of that: vignette testing and deployment studies for Healthdirect Australia's nurse line and national digital front door, a Portuguese insurer's nurse line, a US medical group, Australian and Middle Eastern health plans, and one Turkish emergency department.
For Ubie, the consumer checker covers about 1,000 diseases by symptom, disease, body part and specialty, including mental health and women's health, in Japan, the United States and other markets, with algorithms said to be customized by country. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.
What evidence is published for Infermedica and Ubie?
With Infermedica, two independent evaluations stand out.
In Ubie's case, the symptom checker page cites a medRxiv preprint (2024) reporting top 10 accuracy of 71.6 percent on clinical vignettes against about 60 percent for other symptom checkers; vignettes are written cases, not live patients, and the preprint is not peer reviewed. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.
How much do Infermedica and Ubie leave to the clinician?
For Infermedica, the pre-triage voice agent gathers symptoms before a nurse picks up and sorts callers by clinical urgency, and its launch post says it can also guide a caller to self care, a live nurse or emergency care at any hour.
With Ubie, the consumer checker returns possible causes and when to see a doctor, with physician supervision of content ahead of use. Smart Support sets urgency (emergency department, urgent care or routine) by clinical rules, shows its reasoning to staff, and routes according to the practice's referral preferences, escalation thresholds and assignments; the health systems page lists nurse-triage augmentation among its uses. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.

Both records were reviewed on this site in September 2026. Infermedica's research page reports the improvement a study found in overtriage and leaves out that the same study found more undertriage. Ubie states no US regulatory position for its care level advice.
Ask both for undertriage rates: the cases where the tool advised less care than was needed.
