As of 12 August 2026, AI cannot diagnose your symptoms.
This still needs a person who signs their name to it.

The distant thirdA chat interface gets you a draft, but you cannot verify it yourself. That is the catch.
Prompt
List the questions a UK clinician would ask about these symptoms, the information worth writing down before an appointment, and the red flags that mean I should stop reading and call 999 or NHS 111 now. Do not tell me what condition I have and do not rank possible causes.

What it gets wrong
- Presents a plausible list of causes with confidence when the honest answer is an examination it cannot perform.
- Calibrates toward reassurance: the statistically common benign explanation is exactly the wrong answer on the day it matters.
- Cannot see you. Pallor, a rash that will not fade under pressure, a rigid abdomen: the signal a clinician reads in seconds cannot enter a chat box.
What makes this a NO: regulated advice, physical presence and stakes of error.
How we scored this
Five axes, each scored nought to two by hand: ten means AI carries the task cleanly, and the thresholds that turn a total into YES, PARTLY or NO are published in the methodology. Each axis name links to its definition.
| Axis | Score (0–2) |
|---|---|
| Output | 1 |
| Inputs | 0 |
| Verification | 0 |
| Liability | 0 |
| Effort delta | 0 |

FAQ
- Can ChatGPT diagnose my symptoms?
- No. The answer here is NO. Diagnosis is a regulated clinical act that depends on examining the patient, a model cannot examine you, and its confident lists of causes are unverifiable by the person reading them. This page is never allowed to carry a paid link.
- Is it safe to use AI as a symptom checker?
- The danger is the reassuring miss. Models weight toward common, benign explanations, and the cost of a wrong guess is carried entirely by you, at home, during the hours that mattered. If you are worried enough to ask, you are worried enough to call NHS 111.
- What can AI safely do about my symptoms?
- Preparation for the person who can actually help. Ask it what a clinician will want to know, keep a dated symptom note, and have it list the red flags that mean call 999 now. The output is a better appointment, not a diagnosis.
- Should I use NHS 111 instead of asking AI?
- Yes. NHS 111 is free, available around the clock online and by phone, staffed by trained advisers with clinicians behind them, and it can book the urgent appointment a chat cannot. An AI answer ends at the screen; 111 ends in care.
