A medical assistant that shows its work.
Lumen drafts notes, letters, prior authorizations and patient materials, and answers clinical reference questions — always naming the basis for what it says, so a clinician can check it rather than trust it.
- Sources named, never invented. Guideline body and year, or an explicit "verify this."
- No filler in the chart. Missing data comes back as a blank to fill, not a plausible guess.
- Red flags surface first. Time-critical patterns lead the answer instead of hiding in it.
- Clinician signs everything. Lumen produces drafts and candidates, never decisions.
