Introduction
The question for UK GPs is no longer "should I use AI?" but "which AI should I use for what?"
General Large Language Models (LLMs) like ChatGPT have captured the public imagination with their ability to write poems and pass exams. But in a clinical setting, their "black box" nature creates significant risk. Conversely, specialised clinical tools like iatroX are built for safety but can feel less "magical" for creative tasks.
This guide is a workflow comparison, not a reported head-to-head product test. It identifies the outputs a UK GP may need and the checks each requires.
The core difference: the configured source and learning workflow
- ChatGPT: Source access depends on the product and enabled tools. A response without retrieved evidence needs a different review from a cited search or approved healthcare workflow.
- iatroX: UK-focused reference sits alongside structured examination practice and learning. The useful comparison is the actual source support and task completed, not fluent prose alone.
5 common tasks GPs try to do with “ChatGPT for doctors”
In a typical surgery, you might reach for AI for five main tasks. Here is how the two platforms compare.
- Checking Clinical Guidelines: Quickly finding the first-line antibiotic for a pregnant patient with a UTI.
- Drafting Letters: Writing a compassionate but firm letter to a consultant or a patient support request.
- Differential Diagnosis: Brainstorming potential causes for a complex, undifferentiated presentation.
- Patient Information: simplifying complex medical jargon into a text message or leaflet.
- Summarising Notes: Turning a messy set of consultation notes into a clear summary.
Compare the output required
| Task | What to assess |
|---|---|
| Checking guidance | Applicable source, date and supporting passage |
| Drafting letters | Faithfulness, audience and required review |
| Exploring a clinical question | Scope, uncertainty and evidence support |
| Patient information | Accuracy, readability and local relevance |
| Summarising records | Authorised data access, coverage and omissions |
For iatroX, the attractive starting point is UK-focused reference connected with learning. An employer-approved record workflow is a separate evaluation. The table specifies checks, rather than assigning untested winners.
Risk, privacy, and professional review
Training preferences, organisational permission and clinical verification are separate questions. OpenAI’s data controls allow personal training choices; they do not substitute for an authorised clinical data workflow. A source-linked answer helps inspection but does not by itself establish a better legal defence or remove responsibility for the decision.
A practical tool stack
Choose tools against the task: approved documentation and record workflows, relevant clinical reference, and deliberate learning. These functions increasingly overlap across suppliers. iatroX’s reference and learning can complement an institutional system, with each output reviewed within its intended scope.

FAQ
Is iatroX safer than ChatGPT? For UK clinical questions, iatroX offers a more source-constrained workflow than a general chatbot because it can retrieve NICE and CKS guidance and medicines information from relevant SmPCs on eMC and attach citations. This reduces reliance on unsupported recall but does not eliminate hallucinations, source gaps or clinical risk; verify the citation before acting.
Can I use ChatGPT if I anonymise the data? Technically, yes, but true anonymisation is harder than you think. A combination of age, condition, and location can be re-identified. It is safer to use ChatGPT for generic tasks (e.g., "Draft a letter for a patient with..." rather than "Draft a letter for Mrs Jones who has...").
Is iatroX a medical device? The published status concerns the UK reference-tool component. Educational features have a different purpose; assess the feature and intended use rather than treating an entire platform as one regulated function. iatroX FAQ.
