Check Your Symptoms Online with an AI Assistant
Something doesn't feel right, but you're not sure how serious it is? Which doctor should you see? Do you need to go to the emergency room right now, or can it wait until morning? These are exactly the situations AI symptom checkers are built for — tools that help you navigate a medical situation before seeing a doctor.
What is an AI symptom checker
An AI symptom checker is a program that analyzes your symptom description, asks clarifying questions, and generates a structured response: likely causes, urgency assessment, and a recommendation on which specialist to see. It's not a diagnosis and not a substitute for a doctor — it's a first-line navigation tool.
Symptomatica differs from general search engines and AI chatbots by using specialized medical algorithms: structured clinical questioning following red-flag standards, up-to-date symptom databases, lab reference ranges, and drug interaction data.
How Symptomatica's AI symptom checker works
The assistant works in three steps:
- You describe the situation. By text, voice message, or by attaching a file — a photo, lab results, a PDF discharge summary, or a medical scan. The assistant understands any format.
- The assistant asks clarifying questions. Like a doctor at an initial appointment — it asks about the duration and character of symptoms, existing conditions, age, and sex. This matters: the same chest pain has different likely causes in a 25-year-old woman versus a 60-year-old man with hypertension.
- You receive a structured response. Likely causes of symptoms, urgency assessment (schedule an appointment, see a doctor within 24 hours, or seek immediate care), the recommended specialist, and questions worth asking your doctor.
What the assistant can help with
Symptomatica helps navigate a wide range of medical situations:
- unexplained symptoms — pain, fever, weakness, dizziness;
- lab results — interpreting blood, urine, and biochemistry values;
- medical imaging reports — explained in plain language;
- medication questions — interactions, side effects, dosages;
- preparation for a doctor visit — question lists, relevant documents.
When you need emergency care: red flags
Symptomatica automatically detects signs of emergency conditions. If the assistant says to call emergency services — don't delay.
Call emergency services immediately for:
- chest pain, especially with shortness of breath, sweating, arm or jaw pain;
- stroke signs: facial asymmetry, arm weakness, speech problems (FAST test);
- worsening difficulty breathing;
- loss of consciousness or confusion;
- severe bleeding that won't stop;
- anaphylaxis (throat swelling, rash with difficulty breathing);
- blood pressure above 180/110 with symptoms.
This is not a complete list — the assistant assesses each situation individually. When in doubt, call emergency services.
How to prepare for a doctor visit
One of Symptomatica's core goals is not just to help you understand the situation, but to make your doctor visit as effective as possible. The assistant can:
- structure your complaints in chronological order;
- prepare a list of questions for the specialist;
- suggest which test results to bring;
- explain terms from previous medical conclusions.
Research shows that patients who prepare for appointments in advance receive more precise recommendations and, on average, need fewer repeat visits.
Safety and limitations of AI
It's important to understand that Symptomatica is an informational reference service, not a medical service:
- the assistant does not diagnose or prescribe treatment;
- all responses are informational in nature;
- a doctor makes the final assessment after an in-person examination;
- if you're unsure about urgency — see a doctor or call emergency services.

How Symptomatica differs from ChatGPT
ChatGPT is a general-purpose language model. Symptomatica is a specialized medical system. The difference is fundamental:
- Medical databases. The assistant works not only from model memory but from up-to-date clinical data: lab reference ranges, drug interaction databases, clinical scoring systems (NEWS2, Centor, and others).
- Safety module. Automatic red-flag detection — ChatGPT cannot consistently and reliably identify emergency conditions.
- Context-aware reference ranges. The same lab value can be normal for one patient and abnormal for another depending on age, sex, and condition. Symptomatica accounts for this context.
- Medical file formats. DICOM, NIfTI, PDF summaries, Excel lab tables — the assistant understands medical file formats.
Frequently asked questions
Can AI make a diagnosis?
No. Symptomatica provides informational reference content — a list of likely causes based on your description. A diagnosis is made by a doctor after examination, history, and testing.
How accurate is the AI symptom checker?
Accuracy depends on how complete your description is. The more detail you provide — including symptom duration, character, existing conditions, and medications — the more accurate the assistant's response.
What if the assistant says "see a doctor"?
Follow the recommendation. The assistant doesn't give unnecessary warnings — if it recommends a doctor visit or emergency care, your description contains signs that require professional evaluation.
Does the service work in other languages?
Yes. Symptomatica works in any language and takes into account the local healthcare system when forming recommendations.
Can I attach lab results?
Yes. The assistant accepts photos, PDFs, Excel spreadsheets, Word documents, and voice messages. It extracts data from any medical format, including DICOM and NIfTI imaging files.
How much does it cost?
The first 5 requests are free, no registration required. After that, you top up your balance starting from a small amount. No subscription, no auto-charges. You pay only for the requests you actually use.
Is Symptomatica a medical service?
No. It is an informational and educational reference service. Not a medical service; does not diagnose or prescribe treatment. If you need medical care, please see a doctor.
