Ubie
Ubie is a free AI symptom checker that turns a 3-minute questionnaire into a doctor-ready report.
For a free tool, Ubie earns its keep: a 71.6% Top-10 hit rate it can point to in a published medRxiv study, supervision by 50+ named clinicians, and a report you can actually hand to a doctor. It's the strongest free starting point we've found for a nagging, non-urgent symptom, and it never asks for a card or an account. If you need a definitive answer or have an acute problem, skip it and call a clinician — Ubie gives possible causes, not a diagnosis.

About Ubie
Ubie is a free AI symptom checker built by doctors for anyone who wants a structured read on what might be causing their symptoms — before, or instead of, waiting on a same-week appointment. You answer a short adaptive questionnaire, and Ubie's AI generates a personalized report covering possible causes, treatment information, and when to actually see a doctor. It takes about three minutes, and there's no credit card and no sign-up required to get your report. The questionnaire is customized to your situation rather than generic: it factors in biological sex (male vs. female conditions get different weighting), age, and history including past illnesses, surgeries, family history, and lifestyle. You can enter from four different directions — a symptom (headache, cough, diarrhea, narrow stools, throat swelling), a disease (diabetes, bronchial asthma, hypertension, sleep apnea, PCOS, multiple sclerosis, ulcerative colitis, CKD), a body part (mental, limbs, skin, genital), or a medical specialty (psychiatry, dermatology, neurology, ENT, gastroenterology). The medical backing is where Ubie separates itself from the flood of chat-wrapper symptom tools. Its AI draws on 50K+ published clinical data sources, is supervised by 50+ medical experts including clinicians at Mount Sinai's Icahn School of Medicine, Penn State Health, and the U.S. Department of Veterans Affairs, and is continuously trained through 900+ medical institutions worldwide. Ubie reports a Top-10 hit accuracy of 71.6% in a study published on medRxiv, versus roughly 60% for several leading symptom checkers in comparable assessments. Rounding it out are Doctor's Note (public Q&A answered by medical professionals), a Checkup tool for health maintenance, and a medical information library. Ubie is Japan's top healthcare startup and operates in Japan, the United States and other countries.
Behind the Verdict
Ubie's pitch is narrow and it sticks to it: three minutes, no card, no account, a written report you can take to an appointment. That restraint is the product. Where most symptom tools bury you in a chat box, Ubie runs an adaptive questionnaire that changes based on your biological sex, age, past illnesses, surgeries, family history and lifestyle — so a 30s female with a positive ANA result gets lupus (SLE) surfaced near the top, as one testimonial describes, rather than a generic list. Four entry points matter more than they sound. You can start from a symptom (headache, cough, diarrhea, narrow stools, throat swelling, armpit pain, white spots on tongue), a named disease (diabetes, bronchial asthma, hypertension, sleep apnea, PCOS, multiple sclerosis, ulcerative colitis, CKD), a body part (mental, limbs, skin, genital), or a specialty (psychiatry, dermatology, neurology, ENT, gastroenterology). If you already suspect a condition, starting from the disease is a materially different flow than starting from a symptom, and few free checkers offer both. The evidence layer is the real differentiator. Ubie says its AI is based on 50K+ published clinical data sources, supervised by 50+ medical experts — Maxwell J. Nanes (emergency medicine), Caroline M. Doan (internal medicine), Benjamin Kummer (neurology, Mount Sinai), Charles Carlson (psychiatry, U.S. Dept. of Veterans Affairs), Dale Mueller (cardiothoracic surgery) and Ravi P. Chokshi (OB-GYN, Penn State Health) are named publicly — and continuously trained by 900+ clinical institutions. The company publishes a medRxiv study reporting 71.6% Top-10 hit accuracy against roughly 60% for several leading symptom checkers. That's a claim with a link, not a badge. Recognition is real too: Newsweek's 2024 "World's Best Digital Health Companies," Google Play's 2023 "Best With AI," and a 2023 Digital Health Awards "Best in Class" quarterfinalist placement. Where it doesn't fit: emergencies (chest pain, stroke signs, severe bleeding, a febrile infant), anything needing labs, imaging or a physical exam, chronic disease management, and medication changes. Ubie states plainly that results do not replace professional medical advice. If you aren't comfortable entering personal health details, personalisation collapses — the questionnaire's value is the context you give it. Compared with Ada and WebMD's checker, Ubie's edge is the doctor-facing artifact at the end: you can download the report and bring it to an appointment. Compared with a general-purpose chat assistant, the edge is a curated, clinician-supervised knowledge base rather than open-ended generation. And because it sits alongside Doctor's Note, Checkup and the medical information library, it's a starting point in a small ecosystem rather than a one-off page.

Real-world workflow fit
Concrete scenarios for the personas Ubie actually fits — and what changes day-one when you adopt it.
You have had a persistent cough and narrow stools for two weeks. You open Ubie, start from the symptom, answer the adaptive questionnaire covering biological sex, age, past illnesses and lifestyle, and get a report with possible causes, treatment information and guidance on when to see a doctor.
Outcome: You walk away with a ranked list of possible causes and a clear threshold for booking an appointment — in about three minutes, with no account.
Your PCP has referred you to a rheumatologist and you want to arrive prepared. You run the questionnaire from your symptom set, then download the report and bring the finalized symptom list to the visit.
Outcome: You start the appointment with a written summary of symptoms and conditions to discuss instead of reconstructing it from memory.
A relative was just diagnosed with sleep apnea and you want to understand the condition and whether your own symptoms match. You start from the disease entry rather than a symptom, read the report, and follow up in the medical information library.
Outcome: You get symptom and treatment context for a specific condition, and a sense of whether your own symptoms warrant a clinician visit.
Use Cases
- Check your symptoms in 3 minutes to see possible causes and whether to see a doctor.
- Prepare for a doctor's appointment by generating a symptom summary to discuss.
- Explore common diseases and understand their symptoms and treatments.
- Use Doctor's Note to read answers from medical professionals about health concerns.
- Verify if your symptoms match a suspected condition, like lupus, PCOS or diabetes.
- Download the report to start a conversation with a specialist after a referral.
- Start from a medical specialty like neurology or gastroenterology when you don't know the condition.
- Run a Checkup for routine health maintenance between appointments.
Limitations
- Ubie provides possible causes via a 3-minute AI-driven questionnaire, not a definitive diagnosis, and it states explicitly that results do not replace professional medical advice.
- It reports a Top-10 hit accuracy of 71.6% in a medRxiv study, which means the correct condition is not always in the list.
- Personalisation depends on the context you supply — biological sex, age, past illnesses, surgeries, family history and lifestyle — so skipping those questions weakens the output.
- It cannot order labs or imaging, cannot perform a physical exam, and is not built for chronic disease management, medication changes or treatment monitoring.
- If your situation is acute, go to emergency services rather than a questionnaire.
