Ubie
Japanese health technology company with two AI products. The free consumer symptom checker generates a report on possible causes and when to seek care from a roughly three-minute adaptive questionnaire covering about 1,000 diseases, built on more than 50,000 publications, supervised by more than 50 named physicians and refined on real-world data from more than 1,700 providers.
Smart Support, sold to medical practices and health systems in the United States, is an AI phone assistant that answers patient calls, assesses symptoms and sets urgency by clinical rules, schedules with the practice's live calendar and handles routine requests and after-hours access, priced on usage with a free trial for small practices. The company also runs pharmaceutical partnerships that use the symptom checker to prompt patients toward care, and cites a vignette-based preprint for the checker's accuracy.
Capability Axes
An AI Health Index grade measures what a buyer can verify from public sources on the date shown. It is not a rating of how good the product is. A vendor can build an excellent system and grade low on an axis because it publishes nothing an outsider can check. How grades read
The AI is the product. The free consumer symptom checker is a proprietary algorithm that picks each question from the previous answers and returns possible causes; the company says it has been refined since 2017 on real-world data from more than 1,700 healthcare providers under physician supervision. Smart Support, sold to practices and health systems, is an AI phone assistant that answers patient calls, assesses symptoms, sets urgency, schedules and handles routine requests. The company also runs pharmaceutical partnerships built on the symptom checker's reach.
Remove the models and there is no symptom checker and no phone assistant left to sell.
The rules and the practice's thresholds are described; who checks an individual disposition is not. 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.
Missing: whether a clinician reviews the urgency a patient is given before they act on it, and what the agent does when a caller describes an emergency.
The approach and its training inputs are described, without architecture or versions. The company describes an adaptive questionnaire that chooses each question from prior answers across about 1,000 diseases, built on more than 50,000 publications, supervised by named physicians and refined since 2017 on real-world data from more than 1,700 providers; Smart Support is described as applying transparent clinical rules for urgency rather than keyword matching. No model family, architecture, version history or speech and language models behind Smart Support are named.
The symptom model is presented as in-house and the phone agent's chain is unnamed. The symptom checker is described as a proprietary algorithm built by the company's physicians and engineers; Smart Support's speech recognition, voice and language services are not named, no hosting provider appears, and no subprocessor list was readable. The consumer privacy policy allows transfer to third parties in any country.
Published research exists, short of peer-reviewed validation of the triage the company sells. 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. A peer-reviewed retrospective cohort study led by Gilead Sciences with a Ubie author (JMIR 2026) used the checker's data on 424,893 episodes to study consultation and HIV testing after suggested HIV or STI conditions; it describes behavior, not accuracy.
No evaluation of Smart Support's urgency assignments or of patient outcomes after the checker's advice is published.
The privacy policy (last updated October 2023) covers the consumer apps and gives the company wide latitude. It collects sex, age, history and symptoms without registration, keeps personal data as long as reasonably needed for business and legal purposes, may de-identify data and keep using it, uses aggregate data for statistics, and asks users to consent to transfer anywhere outside their country. Nothing states whether symptom sessions or Smart Support calls train the models, and no retention period is given.
Smart Support records patient calls on behalf of practices, and no policy for that data was readable. Safety engineering, meaning how an unsafe urgency call is caught, is not published.
The consumer privacy policy reaches the symptom checker, and no business associate position is taken for the practice product. The consumer checker collects health information directly from individuals, where HIPAA generally does not attach, under a privacy policy that covers the apps. Smart Support answers patient calls on behalf of practices, which makes the company a business associate for them, and its business site policy pages may say as much.
Nothing public shows an independent check of the company's security. The consumer site links an information security policy and a policies hub, which redirect to the business site, where policy pages are titled for a security management system and a privacy management system. The company names no certification, audit, penetration test or trust portal.
The page titles hint that management system certifications may exist.
Both products assess symptoms and point patients to a level of care, and no regulatory position is stated. Smart Support's clinical page says it evaluates symptoms against clinical rules "to determine what's actually going on" and sets urgency ("ER, urgent care, or routine") "so patients are pointed to the right level of care from the very first contact"; the health systems page sells it to "assess symptomatic needs, determine urgency and next steps". The consumer checker's report tells users "what causes your symptoms" and when to see a doctor. Sorting patients by urgency is triage, and no named protocol or clinician disposition is described.
The terms say the company provides no diagnosis or medical advice and the checker is for information only, which the product pages contradict.
Content governance is published; no evaluation of the model's behavior across groups is. A medical content editorial policy governs production, review and supervision, and more than 50 supervising physicians are named with their specialties and institutions; the clinical data sources page describes a base of more than 50,000 publications. No results are published by age, sex, language, health literacy or region, although the questionnaire conditions on sex and age and the company says its algorithms are customized by country.
Named physicians stand behind the content and staff can see the reasoning; nothing stands behind a wrong answer. The consumer site names each supervising physician and the sources behind the content, and Smart Support's clinical page says it surfaces the reasoning behind each recommendation so the practice team can check it, with routing that follows the practice's own escalation thresholds. The terms say the symptom checker is for information only, the company provides no diagnosis or medical advice, and it disclaims liability for providers' acts.
No accuracy guarantee, correction route or remedy for a patient sent to the wrong level of care is published.
Integration is claimed for the practice product with no system named. Smart Support reads the practice's live schedule to route patients to an available provider, and the company says it handles all EHR integrations during set-up; no EHR, interface or live connection is named. The consumer checker does not integrate with records: patients take a report or doctor's note to their clinician.
Hosted services with location left open. The symptom checker runs as a web and mobile app and Smart Support as a hosted phone assistant; no hosting provider, region or tenant separation is named. The consumer privacy policy asks users to consent to transfer of their data to any location outside their country, and the company operates from Japan and the United States among other markets.
The consumer price is published and the practice product's basis is stated. The symptom checker is free, with no registration or card. Smart Support, sold to practices and health systems, is priced on usage so cost tracks answered calls, offers a free trial for smaller practices and a one-sheet with pricing on request; set-up takes days, with EHR integration handled by the company. No per-call or per-minute rate is published.
Coverage is named broadly, with evidence behind part of it. 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. Smart Support is sold to solo practices, practices and health systems for calls, scheduling, routine requests and after-hours access, with nurse-triage augmentation, referral intake, portal-message triage and post-discharge navigation named for health systems.
The accuracy evidence is a vignette preprint for the consumer checker; nothing is published by setting for Smart Support.
