Announcing Lorraine Chat

Today we are launching Lorraine Chat: clinical AI built for South African practice. For the last year we have spent most mornings sitting with clinicians — in clinic, on call, in the tea-room — asking the same question in different ways. Where does reasoning support actually help, and where does it just add friction? Chat is the first product we are comfortable shipping as the answer.

What Chat is

Chat is a clinical-grade reasoning tool. You describe a case, ask for differentials, check a dose, or look up a guideline — and Chat responds with cited evidence from PubMed, NICE, SA Heart, SAHS, NDoH, and the SAMJ. Every substantive claim is grounded in a source you can audit in under ten seconds. It also ships with the clinical calculators we use most often at the bedside: Wells, CHA₂DS₂-VASc, CURB-65, eGFR, paediatric weight-based dosing.

What Chat is not

Chat is not a medical device and it does not replace clinician judgement. It is decision support — a faster way to think alongside a second opinion that has read the guideline and the recent trial. The moment you stop asking questions, Chat stops being useful.

CPD, built in

Reasoned clinical queries in Chat are automatically logged as HPCSA-compatible CPD activity. Annual summaries are exportable as CSV. The point is to reward the work you are already doing when you check a guideline or re-read a trial — not add another admin load.

Try it at chat.uselorraine.co.za. The free tier gives you 50 conversations a month with open-source citations; the Clinician plan unlocks full citations, all calculators, CPD export, and priority support at R249 a month. Practices and hospitals: talk to us about team deployments.
