Clinical AI/for SA clinicians.
Evidence-based decision support, grounded in SA clinical guidelines and international literature. Built for the real demands of practice — at the bedside, in clinic, on call.
72yo diabetic, 2 days worsening SOB. CXR shows bilateral infiltrates. Troponin mildly raised. Differential?
Key differentials, ranked by pre-test probability: 1. Acute decompensated heart failure — diabetes + bilateral infiltrates + troponin rise. First consider NT-proBNP and echo. 2. Pneumonia with cardiac strain — bilateral CXR findings, especially if febrile. 3. Non-ST-elevation MI — troponin rise deserves serial ECGs and repeat troponin at 3h. 4. Pulmonary oedema from AKI — check creatinine trend and fluid status. SA Heart Association 2023 guideline on ADHF recommends early diuresis if volume-overloaded and haemodynamically stable.

What Chat does well
Four pillars,
grounded in SA practice.
Every response is traceable back to a source, every dose is checked against SA formulary conventions, and every session counts toward CPD.
Evidence-grounded
Citations from PubMed, NICE, UpToDate-equivalent sources, and SA-specific guidelines (SAMJ, SA Heart, NDoH).
Differential support
Structured differentials with pre-test probability reasoning, red flags, and next-step investigations.
CPD tracking
Earn HPCSA CPD points while you consult. Every reasoned query counts toward your annual requirement.
Clinical calculators
Wells, CHA₂DS₂-VASc, CURB-65, eGFR, paediatric drug dosing — embedded directly in the conversation.
In daily use
Three moments
it earns its keep.
- 01
Tough differential
Mid-clinic, a presentation that does not fit the obvious box. Chat structures possibilities with pre-test probability — faster than flipping through a textbook.
- 02
Scripts and doses
Unfamiliar combination, paediatric weight-based dose, or an interaction check. Chat draws on SA formulary data and calls out renal adjustments.
- 03
Guideline lookup
Patient asks what the latest hypertension guidance says. Chat surfaces the 2023 SAHS update with the relevant section quoted, so you can answer on the spot.
What Chat is — and is not.
Clinical decision support, not a medical device. It supports your reasoning and reference workflow; it does not replace your judgement or the ultimate responsibility of a licensed clinician. Patient data is protected under POPIA — avoid personally-identifiable information unless your organisation has a signed agreement.
