Twenty minutes for a complex chart.
Scrolling the EMR looking for the last A1C, the last imaging report, what the cardiologist said in 2022, and what the patient's actually on now.

The problem
Charts have outgrown the time you have to read them.
A long-time patient's chart can run hundreds of pages — labs, consult letters, faxed reports, encounter notes spanning decades. The clinically important answer is in there. Finding it before a 15-minute visit is the work.
Numbers that only matter together.
One A1C is a snapshot. Six A1Cs are the story. The EMR shows you the value; reconstructing the trajectory is on you.
Three years ago, the consult said —
Was it the rheumatologist? The internist? It was a faxed PDF. You'll know it when you see it. You will not see it in the next three minutes.
How it works
Three pieces. None of them leave your clinic.
ChartAI runs on a workstation in your server room. It indexes patient data in the background and answers questions through a side panel that opens next to OSCAR.
-
01
Local install, alongside OSCAR.
Set up on a clinic workstation with a GPU. Connects to your OSCAR database read-only. No cloud, no API keys, no data egress.
-
02
Indexes everything in the background.
Encounter notes, HL7 lab messages, OCR'd faxed PDFs, prescriptions, the disease registry. Continuously, as new data arrives.
-
03
Ask questions, get cited answers.
A side panel inside OSCAR. You type a question about the patient on screen; it answers with sources you can click through to.
What you can ask
Real questions. Real answers. Sources on every line.
Examples below are from production deployments, with patient identifiers removed. Every assistant reply ends with the documents and records it drew from.

Privacy & architecture
PHI does not leave the clinic. Ever.
ChartAI runs on a workstation you own, on your network. It reads from your OSCAR database; it does not write to it. There is no outbound API, no telemetry on chart content, no cloud component on the patient-data path. Inference happens locally; if your internet goes down, ChartAI keeps working.
PHIPA-compliant
Configured to meet Ontario's Personal Health Information Protection Act. PIA template available on request.
Local inference
Open-weight clinical models running on your hardware. No PHI is sent to any third-party model provider.
Audit logs
Every query, every retrieved source, every response is logged on-device. Exportable for chart-access audits.
Declines to guess
If the chart doesn't contain the answer, ChartAI says so and tells you what it checked. It does not invent clinical facts.
Who's behind it
Built with one clinic, in real use.
ChartAI was built in cooperation with a Richmond, BC primary care clinic — used daily by the practising physicians there before any other clinic saw it. Every feature traces back to a question a doctor needed answered during a visit.— Development principle, not a tagline.
Status
In production at one BC clinic. Pre-launch for additional pilots.
Built by
A clinical AI developer working directly with practising family physicians. Not a research lab project.
EMR support
OSCAR EMR.
Hardware
One workstation per clinic. Spec sheet sent with the pilot package.
