A place where all you can do is write.
A Markdown editor that runs in your browser and saves straight to disk. No accounts, no cloud, nothing between you and the page.
Try it. Right here.
No account, no install, no waiting. Type below — this is the real editor, running locally in this page.
Start fresh or open what you already have
Open any existing local folder as a vault instantly — no migration, no conversion. Or create a new one: name it, pick a location, and start writing immediately. No example content, no setup wizard, no configuration to get through first.
Every note is a plain .md file with a small YAML header — title, status, tags. Nothing HermesMarkdown-specific, nothing you can't open in another editor or read in ten years.
Nothing but the page, until you ask for more
Full-screen by default — no toolbar, no rail, no panel until you ask for one. The sidebar opens on hover or from the command palette; open files side by side, drag tabs between panes.
Syntax that reacts, not just renders
A keyboard-first table editor for structuring data — cell grids you navigate and edit without touching the mouse. Not a formula engine: what you type is what gets written back to clean, auto-padded Markdown. Checkboxes toggle on click, dates open a calendar picker, and Ctrl+Click any WikiLink to jump instantly.
- #todo transitions dynamically to #prog and #done via native keyboard interaction
- Export tables to CSV — everything writes back to clean, auto-padded Markdown

No cloud. Your notes stay yours.
Nothing uploaded.
No account or sync required — your vault is a folder on your disk.
Nothing tracked.
No telemetry on note content, ever.
Nothing proprietary.
Plain .md files, readable in any editor, forever.
Open a folder. Start writing.
A minimalist Markdown editor built for focus. Plain .md files. Runs in your browser, saves to your machine.
