ASEAN Perspective
Ubie in Southeast Asia
Ubie opened a Singapore office in 2020 and positions it as an APAC hub, but the product's deep clinical integration — EMR links, hospital workflow tools, Japanese-language UX optimisations for elderly users — is firmly rooted in Japan. No confirmed country-specific rollouts exist for Indonesia, Malaysia, the Philippines, Thailand, or Vietnam as of mid-2026. The NTT Docomo alliance (March 2025) integrates Ubie with 100M+ Japanese d-Account holders, reinforcing Japan-first momentum. ASEAN users can access the English-language symptom checker at ubiehealth.com, but without localised disease prevalence data or regional regulatory clearances the tool's utility in Southeast Asia remains that of a general global product, not a regionally tailored one.
Ubie offers a genuinely useful, free and well-supervised symptom checker, and its move into AI phone agents for clinics has early validation from Mayo Clinic. Treat its accuracy claims carefully: the headline study is Ubie's own unreviewed preprint, and on a like-for-like measure physicians still did better. Good for quick, low-stakes triage guidance in Japan and the US; it is not a substitute for seeing a doctor.
What we found
Ubie is a Japanese health-technology company best known for its free AI symptom checker. Users answer a short questionnaire about their symptoms, without creating an account, and receive a report of possible causes and advice on when and where to seek care; the service was developed and is supervised by doctors and draws on what Ubie says are more than 50,000 clinical data sources. Ubie also publishes free physician-written answers called Doctor's Note. For healthcare providers it sells Smart Support, an AI phone and chat agent that handles after-hours and overflow calls with emergency escalation, which qualified for the Mayo Clinic Platform in August 2026 after a pilot in Mayo's accelerator; in Japan it offers Medical Navi, used by 1,800 institutions, plus generative-AI and coding tools for hospitals, and services for pharmaceutical companies.
Ubie, Inc. was founded in Tokyo in May 2017 and is led by co-chief executives Yoshinori Abe, a physician, and Kota Kubo, with a US company in New York. It has raised ¥10.98 billion in total, with backing that includes Google, and had 240 employees in 2025. It says its Japanese symptom checker has 12 million monthly users and that its tools reach 13 million people a month globally, including more than a million in the US, and that it works with about 90 per cent of the world's largest drug makers — its own figures. In July 2026 it began an obesity digital-care pilot with NTT Docomo.
Ubie points to a study in which its checker listed the correct condition among its top ten suggestions 71.6 per cent of the time. That study is a preprint written by Ubie staff, not peer-reviewed, and on the comparable top-five measure Ubie scored 63.4 per cent against 72.9 per cent for physicians, while still beating other symptom checkers' 57 per cent.
The symptom checker is free. Smart Support costs $850 a month for US practices, and hospital, pharma and enterprise services are quoted. Ubie suits patients in Japan and the US wanting quick triage guidance.

Notable facts
- Ubie's co-founder Dr. Yoshinori Abe was practising medicine when he realised doctors in Japan spend up to two hours on paperwork for every one hour with a patient — that frustration became the company's founding mission.
- An independent 2024 medRxiv study found Ubie's top-10 diagnostic accuracy (71.6%) is within one percentage point of the median physician score (72.9%) on the same clinical vignettes.
- As part of its March 2025 alliance with NTT Docomo, Ubie's symptom checker is being integrated with Docomo's 'd Account' ecosystem — giving it potential reach into over 100 million Japanese mobile subscribers.
- Ubie designed its early Japanese-market UI to resemble karaoke remote controls and ATM buttons, recognising that many elderly patients were unfamiliar with modern smartphone interfaces.
