Ubie is a free, web-based AI symptom checker: you answer a short health questionnaire and receive a report on possible causes, when to see a doctor and which kind of care may fit. The company's own pages also call the free AI symptom checker Ubie Health, and the English service runs at ubiehealth.com.
Ubie describes itself as a Japanese healthcare startup with a mission to build a healthcare guide for everyone, serving Japan, the United States and other countries. Its company pages add that Ubie was founded in Tokyo in 2017 and is based in Japan, Singapore, India and the United States. For the English site, the Terms of Use name the contracting party as Ubie, a company incorporated under the laws of the State of New York.
The Japan option on the site's location selector leads to a separate Japanese-language symptom search service called ユビー, which carries a © Ubie株式会社 notice. The pages reviewed for this profile do not explain how accounts, data or terms are shared between the English and Japanese services, so everything below describes ubiehealth.com unless the Japanese service is named.
The Ubie symptom checker is a roughly three-minute questionnaire that ends in a free AI-generated report on possible causes.
Consult is Ubie's chat-style entry point. Its page offers a standard symptom check plus a newer photo check, and labels the service "Doctor approved. Always free. Always private." According to the company's launch announcement, Consult is built on the Symptom Checker and combines conversational dialogue, smart buttons, photo uploads, over-the-counter (OTC) advice and routing to appropriate medical attention.
Ubie Checkup for Asthma is a condition-specific tracker rather than a one-off check.
Asthma was the only condition-specific Checkup linked from the site's navigation at the time of review.
Doctor's Note publishes answers from current physicians on health concerns, treatment options and management strategies. The site also hosts reference pages on symptoms, diseases, specialties and care options such as urgent care versus the emergency room.
According to Ubie, most of the medical information behind the checker is based on more than 50,000 publications from medical associations and top journals. Its editorial policy says a team of over 50 supervising physicians curates the content, with physicians from each specialty writing and supervising the pages for each symptom and disease. After publication, the team says it revises content based on user feedback and corrects errors it finds.
Ubie's home page reports a Top-10 hit accuracy of 71.6% and says comparator symptom checkers averaged around 60% in similar assessments. The figure traces to a clinical vignette study that gathered 400 public vignettes, analyzed the 328 within Ubie's scope, and reported 63.4% Top-5 and 71.6% Top-10 hit accuracy. That study's record lists Ubie Health as the corresponding institution and shows no journal publication, so the numbers are company-authored results rather than independent validation.
Ubie is built around a handful of concrete situations.
Ubie suits people who want a free, structured first look at symptoms and accept its data terms.

For patients, Ubie is a free symptom checker: the home page presents it as free, three minutes long and developed by doctors.
| Offering | Who it serves | Price shown |
|---|---|---|
| Symptom Checker | Patients | Free |
| Consult | Patients | Free ("Always free") |

The business side explains how a free patient product is funded. For pharma and agency partners, Ubie sells Patient Discovery, which it calls an all-in-one marketing and data collection solution built around the AI Symptom Checker. In June 2026 Ubie also announced a self-serve platform that lets healthcare and pharma advertisers reach patients with targeted, clinically contextual placements inside its AI-driven patient experiences. No paid consumer plan appeared on the pages reviewed.
Ubie competes with other consumer AI symptom checkers. A 2022 technology news report on Ubie named Buoy Health and Ada Health among the companies building AI symptom-check apps.
Ada describes itself as an AI-powered symptom assessment optimized by clinicians, backed by a medical library and enterprise solutions for partners. Buoy pairs an AI that asks questions about your symptoms with clinician-written content and a team that publishes reviews and Top 10 lists of products, services and doctors. Ubie's own additions include the photo check in Consult, the asthma Checkup, clinic-specific pre-visit checkers and a Japanese-language sister service.
The accuracy study itself reports variability across ICD disease groupings and says continued refinement and real-world testing are needed. It measured performance on written clinical vignettes rather than real-world use, and its corresponding institution is Ubie Health.
Ubie's privacy policy covers its apps, including the AI Symptom Checker and AI Health Assistant, and gives the company broad room to use health data.
The privacy policy shows a last-updated date of 30 October 2023, and the Consult page's "Always private" label appears alongside the policy terms above without further explanation.
Yes for patients. The symptom checker, Consult and the asthma Checkup are presented as free, and no paid consumer plan appeared on the pages reviewed. Ubie's paid offerings are aimed at pharma marketers, advertisers and healthcare providers.
No. Ubie describes the checker as an information service that does not constitute medical practice, the Consult launch release says the aim is not to diagnose or prescribe, and the Terms advise against using the service in an emergency.
Ubie cites a 71.6% Top-10 and 63.4% Top-5 hit accuracy on 328 in-scope clinical vignettes. The study's corresponding institution is Ubie Health, it used written cases rather than real patients, and it found accuracy varied across disease groupings.
No English-language app was found in this review. The iOS and Android listings found belong to the Japanese-language service, and a US App Store lookup of that app returned no listing as captured on September 27, 2026. US users use the website.
Under the privacy policy, Ubie may use your answers for its own services, research, advertising and marketing, and may disclose data to business partners including pharmaceutical and insurance companies, service providers and affiliates, including across borders.
