Image and document attachments
Inbound email threads (Nest) can receive attachments sent by clients — photos, lab results, forms. They’re stored alongside the thread and visible in the encounter. You cannot send attachments from Noctune; outbound sends are text-only.
Noctune does not offer PDF export of SOAP notes or discharge summaries. Use the copy-to-clipboard or email flows to get content out.
