Detect HL7 v2 messages on any page and edit them in the Kainos HL7 Editor desktop app — entirely on-device. The Kainos HL7 Editor Companion detects and captures HL7 v2 messages on any webpage and optionally pairs with the Kainos HL7 Editor desktop app for full parsing, editing, field-level validation, and transformation — entirely on your device. KEY FEATURES • Automatic, on-device HL7 v2 detection that stays out of your way — a lightweight check runs only when you focus or paste into a text field, never as a background page scan. Detection works on any site by default; from Options you can limit it to specific sites or block individual sites. • One-click "Edit with HL7 Editor" button opens the message in the full editor for validation, transformation, and field-level editing. • Send your edits back to the page with one click. • Customize the on-page button: standard or compact icon-only size, manual or automatic site-matching color with built-in contrast checking. • Works offline via the system clipboard when the desktop app isn't already open. **Standalone mode — no desktop app needed:** Click the popup and hit "Capture from clipboard" to extract HL7 messages instantly. A lightweight detector content script runs passively on pages to recognize HL7 v2 content as you browse. Use the right-click context menu to send any selected text directly to the editor. **Optional desktop pairing:** This extension is a companion to the Kainos HL7 Editor desktop/web application. Get Kainos HL7 Editor at kainoshealthcare.com/products. When the Kainos HL7 Editor desktop app is running, the extension connects via a secure WebSocket bridge at ws://localhost only. Captured messages open in the full editor for segment-level parsing, field editing, and export. A one-time trust dialog (TOFU pairing) lets you confirm the connection before it is established. **Privacy-first design for healthcare:** HL7 v2 messages frequently contain Protected Health Information (PHI). No data ever leaves your machine. The bridge connects exclusively to 127.0.0.1 / localhost — no external servers, no accounts, no telemetry, no cloud storage. Privacy policy: https://kainoshealthcare.com/privacy/hl7-editor-extension/ Kainos HL7 Editor Companion brings professional HL7 v2 editing to any web page. Detect HL7 messages in a browser text field — an EHR test harness, a support ticket, a lab interface console — and edit them instantly in the Kainos HL7 Editor desktop application, entirely on your device.
