Quick Fill + web clip

Install the browser side of NoteKrypt

The Browser Companion relays Quick Fill and web clipping between your browser and the running NoteKrypt app on desktop. Mobile Quick Fill uses iOS Password AutoFill or the Android Autofill service instead of browser extension packages. Safari ships inside the macOS app. Firefox and Chromium downloads are hosted directly from the NoteKrypt site.

The native host bundle is optional for current public installs. Start with the browser package first, then use the host only if NoteKrypt Settings says the direct bridge needs a fallback.

Notes

  • The Quick Fill shortcut is configured inside NoteKrypt, not inside the browser.

  • The native host bundle is not required for the normal Safari flow and is only a fallback if the desktop browser extension cannot use the direct local bridge.
