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
Links
- Select the text you want to linkify.
- Click the link button in the toolbar.
- Enter the URL in the prompt.
- The selection becomes a markdown link.
Images
- Click the image button in the toolbar.
- Search for an image in the picker (case-insensitive filtering).
- Select an image — the path resolves automatically.
- Edit the alt text.
Tables
- Click the table button in the toolbar.
- Specify the number of rows and columns.
- 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.
