Try it. Right here.
No account, no install, no waiting. Type below — this is the real editor, running locally in this page.
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. Checkboxes toggle on click, dates open a calendar picker, Ctrl+Click any WikiLink to jump instantly.
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.
Build tables without touching the mouse
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. Trigger slash commands anywhere to insert templates or format layouts instantly.
- #todo transitions dynamically to #prog and #done via native keyboard interaction
- Export tables to CSV — everything writes back to clean, auto-padded Markdown
