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.
Type and watch it render: headings, code blocks with real syntax highlighting, diagrams, and math formulas all format live, in place — no separate preview pane to check.
Syntax that reacts, not just renders
Stop wrestling with raw Markdown syntax or reaching for your mouse to format a simple table. This is a keyboard-first, ultra-responsive table editor built for effortless data structuring.
- Flow-state navigation: Navigate, edit, and reorganize entire cell grids entirely from your keyboard.
- Smart native controls: Toggle checkboxes instantly, pick dates with a native calendar, or Ctrl+Click any WikiLink to jump across your vault without breaking stride.
- Dynamic status cycling: Cycle tasks smoothly between #todo, #prog, and #done using native keyboard shortcuts.
- Zero friction, zero lock-in: Export to CSV anytime. Everything writes back directly to clean, auto-padded Markdown — rich, interactive tables that stay 100% future-proof.
