Symptom checker

You describe your complaints in your own words: what bothers you, where, for how long, and how severe it is. The AI analyzes this combination and responds by explaining the likely causes in plain language, assessing urgency, and suggesting the type of doctor and the tests worth discussing at your appointment. The first check is free, and no registration is needed.

No. The service does not make a diagnosis and does not replace a specialist's examination, work-up, and prescriptions. It's informational help so you can better understand your condition and prepare for your visit: what to bring up, whom to see, and which questions to ask. Any treatment is prescribed only by a doctor after an in-person consultation.

Text is enough: where it hurts, how long it's been going on, the nature of the pain, your temperature, what makes it better or worse, and which medications you've taken. If you have test results, you can refer to their values. The fuller you describe the picture and the history of your complaints, the more accurately the AI can work through the situation and suggest next steps.

Don't use the site in acute situations — call emergency services (112) right away. Dangerous signs include severe or rapidly worsening pain, high fever, shortness of breath, chest pain, confusion, facial asymmetry, slurred speech, heavy bleeding, and loss of consciousness. In these cases, every minute counts.

The AI relies on typical combinations of symptoms and gives a rough guide, not a definitive answer. The same complaints can occur with different illnesses, so the result should be taken as a reason to see a doctor, not as a final conclusion. Accuracy is confirmed only by an in-person examination and tests.

You can describe a child's complaints, but a child's body reacts differently and the risks are higher. Treat the result only as a rough guide and, if in any doubt, see a pediatrician. With a high fever, lethargy, a rash, labored breathing, or severe pain in a child, don't wait — call a doctor or an ambulance.

Describe the complaint in the symptom checker — the AI walks through the likely causes (poor sleep, stress, deficiencies, thyroid) and suggests which labs to discuss with your doctor. And to gauge how much your attention and memory are affected right now, try the free tools in the Brain training section: the Schulte table, memory and reaction tests — no sign-up, records stay on your device.

Describe the complaint in the symptom checker — the AI suggests likely causes and which doctor to see. For a quick self-check, the Vision test section has free tools: a visual acuity chart (calibrated to your screen), a colour blindness test, an Amsler grid and an astigmatism test. These are self-checks and a guide: if your vision drops or distorts, see an ophthalmologist, and with sudden vision loss, seek care urgently.
