Ubie
Free AI symptom checker that turns a 3-minute questionnaire into a doctor-ready report on possible causes.
Ubie is the symptom checker I'd actually send someone to before a non-urgent appointment, mainly because the adaptive questionnaire produces a downloadable report a clinician can read. The published 71.6% Top-10 hit rate and named supervising physicians are the kind of receipts most symptom checkers can't produce. It is a triage and preparation tool, not an answer — anyone with acute symptoms should skip it entirely.

What is Ubie?
Ubie — Free AI symptom checker that turns a 3-minute questionnaire into a doctor-ready report on possible causes. Best for Adults with a nagging, non-urgent symptom who want structured guidance before booking a visit, Patients preparing for a specialist appointment who want a written symptom summary to hand over, People researching a named condition like PCOS, sleep apnea, or ulcerative colitis. Free to use.
Ubie is a free AI symptom checker. You answer a short adaptive questionnaire — roughly three minutes — and get a personalized report on what might be causing your symptoms, when to see a doctor, and what treatment information applies. Entry points are unusually broad: start from a symptom like headache or narrow stools, a named disease like PCOS, sleep apnea or ulcerative colitis, a body part, or a specialty such as neurology or gastroenterology. The questionnaire is the product, not the chatbot. Questions adjust to your biological sex, age, and history — past illnesses, surgeries, family history, lifestyle — so you aren't handed a generic checklist. The report is downloadable, which matters if you want something concrete to bring to an appointment. Ubie backs its claims with numbers and names. It says the AI draws on 50K+ published clinical data sources, is supervised by 50+ named medical experts (including reviewers at Mount Sinai's Icahn School of Medicine, Penn State Health and the US Department of Veterans Affairs), and is continuously trained across 900+ medical institutions. A medRxiv-published study reports a Top-10 hit accuracy of 71.6%, against roughly 60% for several leading symptom checkers. No account and no card are required. Beyond the checker, Ubie runs Doctor's Note (public Q&A answered by clinicians), a Checkup tool, and a medical information library, and ships on web plus iOS and Android. It's Japan's top healthcare startup, operating in Japan, the US and other markets. Positioned against prompt-based symptom chat tools, Ubie is a structured triage guide — it gives possible causes, not a diagnosis.

Behind the verdict
Start with the download button. That single feature is why Ubie beats most of the symptom-checker field for practical use: you end up with a document listing possible causes and concerning symptoms that you can hand to a doctor instead of improvising from memory in a 12-minute appointment. We'd reach for it in exactly that scenario — a symptom that's been lingering a week or two, no red flags, and an appointment you haven't booked yet. The adaptive questionnaire earns its keep. Asking about biological sex, age, past surgeries and family history changes which conditions surface, and users in Ubie's own testimonials describe the report flagging lupus when their PCP was already pursuing that referral. Whether or not the top hit is right, the structure is useful for the conversation that follows. Where it bites: there's no clinician on the other end of your specific case. Ubie returns probabilistic suggestions, and a plausible-sounding cause can anchor you before you've seen anyone. Treat the report as a prompt for your doctor, not a conclusion. The closest alternative is a general AI chatbot asked to play doctor. Those will happily answer, but the reasoning is improvised and unrepeatable; Ubie's questionnaire is fixed, auditable and tied to a published accuracy study. For anything involving numbers — bloodwork, imaging, blood pressure readings — neither tool substitutes for the actual test. One caveat on the evidence: the 71.6% figure comes from Ubie's own medRxiv preprint comparing it to several leading checkers. It's better documentation than most competitors publish, but it isn't an independent head-to-head. Read it as a strong signal, not a guarantee. Skip Ubie entirely if symptoms are acute, if you're managing a diagnosed chronic condition, or if you need
Limitations
- Ubie's report is based on a free 3-minute AI questionnaire and is not a diagnosis; the evidence presents it as informational guidance on possible causes, when to see a doctor, and treatment information, not a substitute for professional medical advice.
- Report quality depends on the personal context you supply — biological sex, age, history (past illnesses, surgeries, family history, lifestyle) and symptoms — so skipping or uncertain answers reduce personalization.
- The site evidence covers only the web symptom-checker experience and describes doctor supervision and clinical data sources at a high level, so no underlying AI model, accuracy figures, or integrations are stated.

GeneratedReal-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 throat swelling for ten days and the earliest appointment is Thursday. You open Ubie, start from the symptom 'cough', and answer the adaptive questionnaire covering your age, biological sex, past illnesses and lifestyle.
Outcome: You get a free report listing possible causes, treatment information, and clear guidance on when to see a doctor, and you download it to bring to Thursday's appointment.
Your PCP refers you to a rheumatologist on suspicion of lupus. Before the visit you start a Ubie check from the named disease 'lupus' plus your symptoms, and review the resulting cause list and the report's symptom summary.
Outcome: You walk into the specialist with a written list of symptoms and a shortlist of possible causes, which shortens the intake conversation and gives the clinician your history in structured form.
A friend mentions PCOS and several of the described symptoms sound familiar. You use Ubie's disease entry point for PCOS and separately read the Doctor's Note Q&A and the medical information library on the condition.
Outcome: You understand which symptoms line up, what treatment options are typically discussed, and whether it is worth raising with a clinician — without paying for a visit first.
Use cases
- Check a nagging non-urgent symptom in 3 minutes and see possible causes plus whether to see a doctor.
- Generate a written symptom summary to bring to an upcoming appointment.
- Explore a named condition like PCOS, sleep apnea, or ulcerative colitis and understand its symptoms and treatments.
- Read clinician-written answers on Doctor's Note about a health concern you are unsure about.
- Verify whether your symptoms line up with a suspected condition such as lupus or diabetes.
- Download the report to open a conversation with a specialist after a referral.
- Start from a specialty like neurology or gastroenterology when you do not know the condition.
- Run a Checkup between appointments for routine health maintenance.
Setup time & first value
How long it actually takes to get something useful out of Ubie — broken out by persona, not the marketing-page minute.
No account and no card, so first value is roughly three minutes: open the symptom checker, answer the adaptive questionnaire, and read the report. Allow closer to five minutes if you fill in the history questions properly — that context is what makes the output specific rather than generic. Reading Doctor's Note or the condition library takes as long as you want to spend.
Switching to or from Ubie
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a general-purpose chatbot: replace improvised medical answers with Ubie's adaptive questionnaire built on 50K+ clinical data sources.
- →From a generic symptom checklist site: gain personalization by biological sex, age, history and lifestyle instead of a fixed question list.
- →From searching symptoms one at a time: enter from a disease, body part or specialty and get a consolidated report.
- →From a paper symptom diary: download the Ubie report to bring the same structured summary to your appointment.
- ↗To a clinician or urgent care: bring the downloaded Ubie report to your appointment for an actual diagnosis and any needed labs or imaging.
- ↗To emergency services: for chest pain, stroke signs, severe bleeding or a febrile infant, skip the report entirely and call emergency services.
- ↗To a chronic-care program: Ubie is not built for medication changes and treatment monitoring, so move that work to your care team.
