Write Markdown with a colour-coded source pane, a live preview, and spell check and Grammarly that actually work. Free, no sign-up, nothing uploaded.
Tab indents the current line. To move focus out of the editor, press Escape and then Tab. Press Command or Control plus 1 to 6 for headings, and Shift plus Enter for a plain line break inside a list. Inside a table, Tab and Shift plus Tab move between cells and Enter starts a new row, and typing a colon followed by two or more letters offers emoji shortcodes that Escape dismisses.
A free account keeps documents in the cloud, private by default, with share links and a document API your agents and scripts can read. This editor keeps working exactly as it does now without one.
Your browser spell checker and Grammarly run here, because the writing surface is a real text field — editors built on Monaco, CodeMirror or Ace cannot support either.
Headings, links, code, tables, tasks and callouts are colour-coded as you type, in both light and dark themes.
Enter carries bullets, numbers and task boxes to the next line, and ends the list on an empty item. Tab and Shift+Tab nest.
A URL over selected text becomes a link, spreadsheet cells become a table, and copied rich text arrives as Markdown.
KaTeX math, Mermaid diagrams and GitHub alerts such as > [!NOTE] all render live in the preview.
Regular expressions with $1 capture groups in the replacement, and every match highlighted across the document at once — not just the one you are standing on.
Word, PDF, HTML, Markdown, rich text, Slack, Discord, Telegram, WhatsApp, Jira, BBCode and plain text — all converted in this browser.
The status bar says when the draft was saved, warns if storage is full, and tells you when another tab changed it.
Every conversion and export runs locally. Open your Network tab while you type — the document never leaves the page.

Our editor provides a split-pane view with the raw Markdown on one side and the rendered preview on the other.
Yes. Your browser's built-in spell checker underlines misspellings as you type, and extensions such as Grammarly and LanguageTool work too. There is a toggle in the toolbar to turn it off. Most online Markdown editors are built on code-editor engines like Monaco, CodeMirror or Ace, which replace the browser's text field with a custom drawing surface — that is why spell check and Grammarly do not work in them. This editor keeps a real text field underneath and paints the syntax colours behind it.
Yes, your draft is saved automatically to your browser's local storage, and the status bar shows when the last save happened. If storage is full or unavailable the editor says so rather than failing silently, and if you have the editor open in two tabs it warns you before one overwrites the other. Nothing is uploaded — the draft only ever exists on your device. If you would rather reach a document from another machine, a free account adds private cloud documents with autosave, share links and an API, and it is entirely optional.
Yes. The Export menu downloads Markdown, HTML, Word (.docx) and PDF, and copies your document converted for Slack, Discord, Telegram, WhatsApp, Jira, BBCode, rich text for Google Docs, or plain text with the syntax stripped. Every conversion runs in your browser, so nothing is sent to a server and there are no watermarks or export limits.
Yes. Toggle the regex button in the find bar and your pattern is applied as a JavaScript regular expression, with $1 to $9 inserting capture groups in the replacement and $& inserting the whole match. Every match is highlighted in the source pane at once, and Ctrl/Cmd + G steps through them without returning to the find field. An invalid pattern is reported rather than silently matching nothing.
Yes. Pressing Enter inside a bullet, numbered or task list starts the next item, numbered lists increment, checked boxes continue as unchecked, and pressing Enter on an empty item ends the list or outdents a nested one. Tab and Shift+Tab indent and outdent, and Shift+Enter inserts a plain line break inside an item. Pasting cells copied from Excel, Google Sheets or Numbers produces a formatted Markdown table.
Yes. Use blockquotes such as > [!NOTE], > [!TIP], > [!IMPORTANT], > [!WARNING], or > [!CAUTION] to render styled documentation callouts.
Yes. Inline and block LaTeX math render with KaTeX, and fenced mermaid code blocks render as diagrams in the live preview.
Yes, use the Format button in the editor footer to clean spacing, standardize list markers, and align Markdown tables locally in your browser.
