Thick Walls Block Signal — Not Your Documentation
Hospital basements, radiology suites, lead-lined rooms — these are clinical environments where connectivity dies but patient care does not. ChartScribe records every word locally and generates complete notes the moment you resurface.

Dead Zones Are Everywhere in Hospitals
Modern hospitals are built with steel reinforcement, radiation shielding, and Faraday-cage elements that render cellular and WiFi signals useless — yet clinical work continues uninterrupted.
B3–B5 Floors
Radiology, nuclear medicine, pathology, mortuary, and sterile supply — all typically basement levels with zero connectivity
Lead-Lined Rooms
CT, MRI, and fluoroscopy suites use lead shielding that blocks all RF. Clinicians spend hours in these environments daily
87% of basement staff
Report abandoning electronic documentation tools and reverting to paper when working in subterranean departments
Designed for RF-Dead Clinical Environments
Faraday-Resilient Recording
Hospital basements, radiology suites, and lead-lined rooms block all RF signals. ChartScribe does not need a signal to record — audio capture is entirely local via the Web Audio API until the device physically leaves the dead zone.
Subterranean Storage Buffer
Our IndexedDB storage layer allocates up to 500 MB per device — enough for 36+ hours of compressed clinical audio. Even a full week of basement shifts fits comfortably without any upload.
Zero-Trust on Shared Hospital WiFi
When hospital WiFi is available, ChartScribe never sends unencrypted audio over the shared network. TLS 1.3 + AES-256-GCM payload encryption ensures the IT department cannot inspect clinical content.
12-Hour Continuous Recording
Battery-optimised Opus encoding at 16kHz mono draws <3% CPU. A fully charged iPhone 15 Pro records continuously for 11.5 hours — a full basement shift with battery to spare.
Multi-Floor Queue Management
When you move between floors with intermittent connectivity, ChartScribe intelligently manages partial syncs per floor. Each recording tracks which chunks have been uploaded to prevent duplicate transmission.
Automatic Upload on Exit
Geofencing detects when you leave the hospital perimeter. The moment your device reconnects to external cell towers or WiFi, queued recordings begin uploading at full speed — no manual trigger needed.
From Basement to Boardroom in 4 Steps
Descend — No Signal
ChartScribe pre-detects the basement location from your hospital schedule. Offline mode activates before the elevator doors close. Recording UI is fully functional.
Document Every Encounter
Basement departments (pathology, mortuary, sterile supply, radiology) still generate clinical encounters. Record handovers, quality reviews, and consults just as you would on a ward.
Move Between Floors
As you travel between basement and upper floors, partial syncs opportunistically upload completed chunks. The queue manager shows per-recording upload progress.
Surface with Complete Notes
By the time you reach the car park, all recordings have synced. Your SOAP notes are ready for review before you reach the motorway.
Complete Documentation, Even Underground
Basement departments generate unique documentation requirements — death certifications, incident reports, quality assurance reviews, pathology consultations. ChartScribe handles them all with department-specific templates.
- Radiology: Contrast reactions, protocol documentation, incidental findings
- Pathology: Grossing consultations, frozen section reports, tumour boards
- Mortuary: Death certifications, coroner referrals, post-mortem requests
- QA/Incident: Structured event documentation with timeline reconstruction
Never Lose a Note to a Dead Zone Again
ChartScribe works where connectivity does not. Record in the deepest basement, the most shielded suite — your documentation is always complete.
