The best Ada Health alternatives are Pymander, a free AI doctor you text, plus the free symptom checkers Ubie, Buoy, and WebMD, and Doctronic if you need a paid visit with a doctor. Pymander publishes this site, and it is our pick for most US adults because it is free by text, asks follow-up questions, gives you a plan, and tells you when to see a clinician or get emergency care. Ada itself is a good free tool: it runs a structured assessment and gives you a report of possible causes. Pick the alternative that fits the job you need done, and call 911 in an emergency.
Pymander: a free AI doctor you text
- Free, by text: no app, no account, no insurance, 24/7 for adults in the US.
- A full consult, not a checklist: it asks follow-up questions, gives you a plan, and tells you when you need a clinician or emergency care.
- Remembers you: your history carries over between visits.
- Published results: top five on HealthBench Hard and 98.2% on the USMLE.
Pymander makes this site. It is a medical AI system, not a licensed doctor, and it does not prescribe.
What does the Ada symptom checker do?
Ada calls itself "an AI-powered symptom assessment optimized by clinicians." You can start it on the web or in the app for iOS and Android. Ada calls it a free symptom checker "built on AI and clinical evidence."
On its web assessment page, Ada says you enter your age, BMI, symptoms, and how long you have had them, and it maps them "against 3,600 known medical conditions." Its help page says you then answer follow-up questions and get "a report of possible causes," with how likely they are.
Ada reports 15 million users and 30 million completed assessments, and it also runs a medical library it says is written by its doctors. Ada is a strong pick if you want a structured, step-by-step check of one symptom.
Why look for an alternative to Ada?
A symptom checker asks set questions and ends with a report. That works for one symptom. It is less useful when you want to ask a follow-up, ask about a medicine you take, or ask what to do tonight. Our answer on AI doctor vs symptom checker covers that difference in more depth.
Common reasons people look elsewhere:
- You want a conversation: to ask "what if" questions without starting a new assessment.
- You do not want an app: some tools work by text or in a browser.
- You want a plan, not only a list: what to do next and how urgent it is.
- You need a prescription: no symptom checker can write one. You need a licensed clinician.

When should you get care?
In an emergency, call 911Get same-day care, from urgent care or your doctor, for a mild illness like a cold, flu, earache, sore throat, low fever, or a small rash when you cannot wait for your regular doctor. If you are not sure how serious it is, call your doctor or your insurer's nurse advice line.
Call 911 or go to the ER for severe chest pain or pressure, pain in the arm or jaw, trouble breathing, fainting, sudden weakness or drooping on one side of the body, sudden trouble speaking, seeing, or walking, sudden confusion, a sudden very bad headache, high fever with headache and a stiff neck, coughing or vomiting blood, heavy bleeding, a severe allergic reaction with swelling or trouble breathing, a seizure, or a possible poisoning or overdose.
If you are thinking about hurting yourself or others, call or text 988.
How our AI doctor decides when to send you to care ›Can any of these tools diagnose me?
No. Symptom checkers and AI doctors give you possible causes and guidance, not a diagnosis. Ada's report lists possible causes, Buoy says its content "is not a substitute for professional medical advice, diagnosis, or treatment," and WebMD says its tool is for informational purposes only.
None of these can examine you or run a test. Use them to understand what might be going on and what to ask about, then bring what you learned to a clinician if you need one.
