Markdown Editor

Markdown files (.md, .markdown, .mdx) open in a live rendered editor. You edit the formatted output directly — headings, bold, lists, tables, and code blocks render as you type.

Formatting toolbar

The toolbar provides one-click formatting:

  • Bold, italic
  • Headings (H1–H6)
  • Ordered and unordered lists
  • Blockquote
  • Code block
  • Horizontal rule

Guided insertion

  1. Select the text you want to linkify.
  2. Click the link button in the toolbar.
  3. Enter the URL in the prompt.
  4. The selection becomes a markdown link.

Images

  1. Click the image button in the toolbar.
  2. Search for an image in the picker (case-insensitive filtering).
  3. Select an image — the path resolves automatically.
  4. Edit the alt text.

Tables

  1. Click the table button in the toolbar.
  2. Specify the number of rows and columns.
  3. A markdown table with header and separator rows is inserted.

Rich/Source toggle

Switch between the rendered view and raw markdown source at any time. Content state is preserved across toggles — edits in one view appear in the other.

Find and replace

Press Cmd+F to open find and replace. Features:

  • Case-insensitive matching
  • Match highlighting
  • Navigate between matches
  • Replace next or replace all

Code blocks

Fenced code blocks render with language-aware syntax highlighting based on the language identifier.

Autosave

Changes save automatically after approximately 450ms of inactivity. An unsaved indicator appears in the tab while changes are pending.
