Pinion.md
A Markdown-first writing tool for people who think in plain text. Open a file, write, save it back to the same place — no account, nothing uploaded.
Most Markdown editors want you to live inside their app and their storage. Pinion.md works the other way: it reads and writes the Markdown files already on your disk, then gets out of the way.
What it does
- Three view modes — Preview, Edit, and Split.
- Opens, saves, and reloads files directly on your device via the File System Access API.
- Clean rendered output with syntax-highlighted code blocks.
- Runs in the browser as a PWA — installable, works offline once loaded.
- No account, no upload, no lock-in. Your files stay yours.
Who it's for
Anyone who keeps notes, docs, or drafts as .md files and wants a fast,
distraction-free way to read and edit them without importing into yet another app.
Status
Live — v1.0. Shipped May 2026. On the roadmap for a future update: a dark-mode toggle, recent files, drag-and-drop open, in-file search, and find-and-replace. Want one of those sooner? Say so.
Questions
Where are my files stored?
On your own device. Pinion.md opens and saves through your browser's File System Access API; nothing is uploaded to a server. See the privacy policy.
Which browsers support it?
The File System Access API works in Chromium-based browsers (Chrome, Edge, Brave). In browsers without it, you can still preview, but save-to-disk may be limited.
Does it work offline?
Yes. It's a PWA with a cache-first service worker, so once it has loaded it keeps working without a connection.
