Ada Health
Ada Health is a free AI symptom checker that asks follow-up questions, suggests possible causes, and points you to the right level of care in six languages.
For low-acuity symptom triage, Ada is the free option I'd actually point someone to. The clinical evidence behind it — 38.5% of planned ED visits redirected to lower-acuity care after a single assessment, 216% more clinically appropriate care decisions (Cotte et al., NEJM AI, 2026) — is stronger than what most paid symptom checkers publish. Compare that with a paid telehealth subscription where the symptom checker is a funnel into a $40 consultation, or a general-purpose chatbot that will answer a health question with no clinical review behind it. Just don't mistake Ada for care: there's no doctor on the other end, no prescriptions, no lab orders, and no chronic-condition management.

Skip Ada if you need a clinician to diagnose, prescribe, or order tests, if you're managing a chronic condition, or if your symptoms are severe enough that you're considering calling emergency services.
The free Personal tier covers your own symptom assessments — white-label sypmtom checking, API access, and triage analytics are sold separately to health systems, payers, and pharma, so organizations can't get those
The consumer app is free, which puts Ada below paid symptom-checker chatbots and telehealth subscriptions that charge monthly and bundle a consultation upsell. Enterprise pricing is custom and aimed at health systems, payers, and pharma — organizations with budget for population-scale deployment, not small clinics. If you're an individual, the free tier is the whole product you need.

About Ada Health
Ada Health is a free AI symptom assessment app for everyday, non-emergency health questions. You answer a series of personalized questions about what you're feeling, and Ada returns a clinically reviewed assessment of possible causes plus a suggested next step — wait it out, call a nurse, see a GP, or go to urgent care. It's designed for low-acuity moments: a rash you can't identify, a cough that's dragging on, a fever that won't break. The consumer app runs on iOS and Android and is available in English, German, Spanish, Portuguese, Romanian, and Swahili, so multilingual households and travelers can use the same tool in their own language. Ada's medical library is written and reviewed by clinicians, with plain-language articles on everything from staying cool in extreme heat and protecting your heart in hot weather to avoiding Lyme disease. You can track symptoms over time, keep a history of past assessments, and export a report to bring to an appointment. In August 2026 Ada shipped an app update that folds in the latest clinical knowledge, redesigns the assessment report, retires a handful of older features, and lays groundwork for AI-driven additions. On the business side, Ada sells a separate enterprise offering to health systems, payers, and pharma: white-label symptom checking, an API that intercepts patients at their first symptom, triage and routing analytics, and patient-finding programs that reach people before any claim, specialist visit, or ICD-10 code exists. Published research in NEJM AI (Cotte et al., 2026) reports that 38.5% of patients who planned an ED visit chose lower-acuity care after a single Ada assessment, and that clinically appropriate care decisions rose 216%. The consumer assessment costs nothing and isn't bundled with a consultation upsell, which separates Ada from paid symptom chatbots and telehealth subscriptions. It is not telemedicine, it does not manage chronic conditions, and it should never stand in for emergency care.
Behind the Verdict
Ada's consumer product does one thing and does it in a structured way: it takes a vague symptom and turns it into a documented, shareable assessment. The parts that matter are the adaptive question flow (each answer changes what it asks next, which is what separates a symptom assessment from a search engine), the clinician-written medical library behind it, and the export — a symptom timeline you can hand to a doctor instead of trying to reconstruct two weeks of feeling off from memory. The August 2026 update refreshed the clinical knowledge base, redesigned the assessment report, and retired some older features while preparing for AI-driven additions, so the reporting side is the most current it has been. Language support is genuinely useful rather than a checkbox: English, German, Spanish, Portuguese, Romanian, and Swahili cover a lot of households that otherwise translate health advice on the fly. Where Ada stops is equally clear. It is not telemedicine — there is no video visit and no clinician to talk to. It does not manage chronic conditions or adjust medications. It does not order labs or write prescriptions. The free consumer tier does not include the white-label deployment and API access that health systems, payers, and pharma partners get, and those are sold through a partnerships conversation rather than a self-serve plan. Our scrape did not reach Ada's docs or developer pages, so we can't characterize the API's documentation or developer experience — don't read the absence as a gap. For a person with a non-urgent symptom who wants a second opinion before deciding whether to spend an evening in urgent care, Ada is a free, evidence-backed first stop. For anyone who needs a diagnosis, a prescription, or ongoing management, it's the wrong tool, and Ada says so itself.

Real-world workflow fit
Concrete scenarios for the personas Ada Health actually fits — and what changes day-one when you adopt it.
You've had a cough for ten days and can't tell whether it's worth a GP visit. You open the Ada app, answer the adaptive question flow about duration, fever, and breathing, and get an assessment of possible causes with a suggested next step.
Outcome: You export the assessment report and take it to your appointment, so the doctor gets a structured timeline instead of a verbal summary.
You're traveling in a region where you don't speak the local language and start feeling unwell. You switch Ada to Romanian, Swahili, Spanish, German, or Portuguese and run the assessment in a language you actually think in.
Outcome: You get a plain-language read on whether this is a wait-it-out situation or something that needs a clinic, without translating health advice on the fly.
Your ED is absorbing low-acuity patients who don't know where else to go. You deploy Ada's API to intercept patients at their first symptom and route them to the appropriate care setting, with white-label branding on the front end.
Outcome: You get triage and routing analytics on where patients were diverted, and the clinical evidence package from NEJM AI (Cotte et al., 2026) to support the program internally.

Models Under the Hood
as of 2026-09-22
Limitations
- Ada provides AI-driven symptom assessment and health information, but it isn't a substitute for professional medical advice, diagnosis, or treatment.
- There is no clinician on the other end of a consumer assessment, so it can't diagnose, prescribe, order labs, or manage a chronic condition.
- For emergencies you should call emergency services.
- The free consumer version doesn't include the white-label deployment, API access, or triage analytics that health systems, payers, and pharma partners get.
- The medical library is extensive but won't cover every rare condition or individual circumstance.
- We did not reach Ada's docs or developer pages this run, so we can't speak to API documentation or developer experience.

Personal
$0/mo
Ideal for
An individual with a non-urgent symptom who wants a free, structured read before deciding whether to see a doctor, or a multilingual household that needs guidance in Romanian, Swahili, Spanish, German, or Portuguese.
What this tier adds
Free entry point: the full AI symptom assessment, clinician-written medical library, symptom tracking, assessment history, and report export on iOS and Android.
Enterprise
Custom
Ideal for
Health systems and payers trying to divert low-acuity patients away from the emergency department, and pharma teams reaching patients before any claim or ICD-10 code exists.
What this tier adds
Adds white-label symptom checking, API-based patient triage, routing analytics, custom branding, pharma patient-finding programs, and the NEJM AI clinical evidence package — sold through a partnerships conversation with custom pricing.
Where the pricing makes sense
The company stage and team size where Ada Health's pricing actually pencils out — and where peers do it cheaper.
The consumer app is free, which puts Ada below paid symptom-checker chatbots and telehealth subscriptions that charge monthly and bundle a consultation upsell. Enterprise pricing is custom and aimed at health systems, payers, and pharma — organizations with budget for population-scale deployment, not small clinics. If you're an individual, the free tier is the whole product you need.
Setup time & first value
How long it actually takes to get something useful out of Ada Health — broken out by persona, not the marketing-page minute.
For an individual, setup is a download and a few minutes of answering questions before your first assessment — call it 5-10 minutes to first value. For a health system, payer, or pharma partner, deployment runs through a partnerships conversation and custom integration work, so expect a procurement and implementation cycle rather than a same-day launch.
Switching to or from Ada Health
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 AI chatbot: move health questions into Ada, where the assessment flow is clinician-reviewed and produces an exportable report instead of an open-ended answer.
- →From a web search for symptoms: replace scattered article reading with a structured assessment that adapts to your answers and suggests a specific next step.
- →From a paid telehealth symptom checker: keep the free assessment and drop the consultation-bundle subscription if you only wanted triage guidance.
- ↗To telehealth or a primary care visit: take your exported Ada assessment report into the appointment as a symptom timeline.
- ↗To emergency services: if symptoms are severe or worsening, stop using any symptom checker and call your local emergency number.
- ↗To chronic-condition management: Ada doesn't manage ongoing conditions or adjust medications, so that work belongs with a clinician and a condition-specific tool.
