An offline notes app that always works

OriginText is an installable Progressive Web App built to work with no internet. Write, read, and navigate your notes on a plane, in a tunnel, or anywhere else — your data is always available because it lives on your device.

Offline by default

A service worker caches the entire app shell and editor on first load. After that, OriginText starts instantly without any network request — there is no spinner waiting for a remote server. Every note you write is saved locally before anything else happens.

Your data is on your device

Notes are stored in your browser’s on-device storage (OPFS / IndexedDB), encrypted at rest. Nothing leaves your machine unless you explicitly enable encrypted sync. This is the core of what it means to be local-first: your data is yours, permanently.

Install it anywhere

Because OriginText is a PWA, you can install it on Windows, macOS, iOS, and Android directly from the browser — no app store required. It gets its own window, its own icon, and behaves like a native app while staying up to date automatically.
