Your health numbers, finally in plain English.
Enter or upload your lab results, vitals, sleep data, and how you feel. Northstar explains each number, shows its reference range, surfaces gentle trends over time, and prepares a clean summary for your next doctor visit.
From scattered results to a clear picture.
Every feature in Northstar is built around one question: what do my health numbers actually mean?
Plain-English lab and vitals explanations
Every number you enter gets a plain-language explanation: what it measures, what it reflects about your health, and where it sits relative to a general reference range.
Reference ranges, clearly marked
Northstar shows the standard reference range next to your result and marks whether you are in range, borderline, or outside it. No guessing, no jargon.
Gentle trends over time
As you add results over time, Northstar draws a calm picture of where things have been and which direction they are heading. Patterns you can actually bring to your doctor.
Doctor-discussion points
Before your visit, Northstar surfaces one or two questions grounded in your own results. Nothing invented. Just the things your numbers suggest are worth raising.
Shareable visit summary
A clean, one-page summary of your recent labs, vitals, trends, and prepared questions. Share it with your care team so the appointment stays focused on conversation.
Upload lab PDFs and photos
Got a PDF from your patient portal, a printed report, or a photo? Northstar reads all of them and pulls in the values automatically.
Secure and private
Your health data is encrypted in transit and at rest, never sold, and never used to train commercial AI models. Export or delete everything from Settings at any time.
Model-agnostic AI
Northstar routes across the best available language models. As the technology improves, your explanations improve too, without you changing anything.
Every number explained, with its reference range.
When you add a lab result, Northstar tells you what it measures, where the standard reference range sits, and whether your result falls inside or outside it. You see a clear picture instead of a number you have to look up yourself.
If a result is borderline or outside range, Northstar prepares a calm discussion point for your next doctor visit. It does not tell you what to do about it. That conversation belongs with your clinician.
Hemoglobin A1c (HbA1c)
Above range5.9%
What this means
HbA1c reflects your average blood sugar over the past two to three months. A result of 5.9% sits in the pre-diabetes range (normal is below 5.7%). This is worth discussing with your doctor at your next visit.
