Medical AI chatbot — free, anonymous, answers in seconds
A chatbot built for medical questions rather than general chat. Describe a symptom, name a medication, paste a lab value or upload a photo, and get a structured answer with an urgency level and the red flags that matter. No account, nothing stored, any language.
What the medical AI can do
- Symptoms. “Sharp pain under my right ribs after eating” becomes a set of targeted questions and then a ranked list of likely causes, with a clear statement of how urgent it is.
- Medications. Interactions, side effects, what to do about a missed dose, whether an over-the-counter option is reasonable with the conditions you mention.
- Lab results. Upload the report or type the values; each one is explained in plain language and patterns across values are pointed out. The dedicated page is the free AI blood test analyzer.
- Skin and visible problems. A photo of a rash, mole, bite or injury gets a visual assessment — see the AI dermatologist.
- Second opinions. Paste what you were told and ask what questions you should be asking at the next appointment.
- “Is this normal?” questions you would not bother a doctor with but still want answered properly.
What makes it a medical chatbot, not a general one
General-purpose chatbots are optimised to answer whatever they are sent, in one go. A medical consultation does not work like that: the first message almost never contains enough to reason from. Dr.Khan is prompted as a clinician. It takes the complaint, asks two or three questions that actually change the answer, checks relevant history, and only then writes an assessment. Every assessment carries an urgency level — routine, monitor, urgent, emergency — and a red-flag list, so the most important sentence is never buried.
It also treats the conversation as one case. You can answer in any order, add a detail ten messages later, or push back on something it said, and it will not lose the thread or re-ask what you already told it.
Why it is free
The product is the conversation, not your data. There is no account because an account would need an identity, and no transcript store because that would need protecting. The cost of running the models is small enough per consultation to keep the service free with a fair-use limit per session. If you find it useful, the same chat is in the iOS app; it costs nothing there either.
How to get the most from it
- Start with the one thing that worries you most, in your own words.
- Answer the follow-up questions honestly — severity, timing, what you have already tried.
- Mention long-term conditions and regular medications; they change the answer.
- Ask “what would make this urgent?” if the urgency line is not clear to you.
- Copy the assessment if you intend to show it to a clinician — nothing is saved for you.
Where it stops
It cannot examine you, order tests or prescribe, and it is not for emergencies. Chest pain with sweating, trouble breathing, stroke signs, heavy bleeding, a severe allergic reaction or thoughts of harming yourself need emergency services, not a chatbot. The AI says this itself when it recognises the pattern; this page says it first.
Frequently asked questions
- What is a medical AI chatbot?
- A chatbot whose model and prompts are set up for clinical reasoning rather than general conversation. It asks the questions a clinician would ask (onset, severity, what makes it better or worse, associated symptoms), keeps the whole conversation in mind, and returns a structured answer — assessment, urgency, next steps, red flags — instead of a paragraph of generalities.
- Is the medical AI really free?
- Yes. There is no trial, no premium tier for “better answers”, and no card on file. Heavy use in a single session is rate-limited to keep the service free for everyone, which in practice does not affect a normal consultation.
- How is this different from asking ChatGPT a medical question?
- Three ways. It runs a consultation — it gathers information before it answers — rather than replying to a single message. It is explicit about urgency and red flags on every answer, which general chatbots often soften. And it does not require an account or keep your conversation; a general-purpose chatbot stores chats by default and ties them to your identity.
- Can it read my lab results or a photo?
- Yes. Lab Result mode reads a photo or PDF of a report and explains each value; Photo Consult mode looks at a picture of a rash, mole or injury and gives a visual assessment. Both are part of the same chat, so you can go from a photo to a question to a lab value without starting over.
- Does it work in my language?
- Write in any language and the reply comes back in it — Spanish, Arabic, Hindi, Urdu, Bengali, Portuguese, French, Tagalog and most others. No setting to change.
- What can’t a medical AI chatbot do?
- It cannot examine you, order tests, prescribe, or diagnose with certainty, and it is not a substitute for emergency care. Its job is to help you understand what is going on and decide what to do next — including when “next” is a clinic or an emergency department.
- Is my conversation stored?
- No. There is no account to attach it to, and transcripts are not saved to a database on our servers. The session lives in your browser; close the tab and it is gone unless you copy it.
