ServiceNow Markdown Composer

Write markdown comments in ServiceNow with live preview and formatting tools ServiceNow Markdown Composer transforms how you write comments and work notes in ServiceNow. Instead of struggling with plain text fields, get a full-featured markdown editor with live preview, rich formatting tools, templates, image uploads, and more — all inside a polished modal that works seamlessly with your existing ServiceNow workflow. Whether you're documenting case resolutions, writing detailed work notes, or communicating with customers, this extension helps you produce clean, professionally formatted content in seconds. WHY INSTALL THIS EXTENSION? If you use ServiceNow daily, you know the pain: plain text fields with no formatting, no preview, and no way to structure your thoughts. Copy-pasting from external editors breaks formatting. Writing HTML by hand is tedious. ServiceNow Markdown Composer solves this by giving you a dedicated writing environment — right inside ServiceNow — with everything you need to write well-formatted comments efficiently. Write & Preview Side-by-Side Open the composer on any ServiceNow case and get a split-pane editor: write markdown on the left, see the formatted HTML preview on the right — updated in real time as you type. Rich Formatting Toolbar One-click buttons for all common formatting: - Bold, Italic, Underline, Strikethrough, Highlight - Headings (H1, H2, H3) - Ordered and Unordered Lists (works on multi-line selections) - Links, Code Blocks, Inline Code - Blockquotes, Tables, Horizontal Rules Keyboard Shortcuts Work faster with familiar shortcuts: - Ctrl+B (Bold), Ctrl+I (Italic), Ctrl+U (Underline) - Ctrl+K (Insert Link), Ctrl+F (Find & Replace) - Ctrl+Shift+H (Highlight) - Ctrl+Enter (Insert to Comments) - Alt+Enter (Insert to Work Notes) - Ctrl+Shift+Enter (Insert to Resolution Notes) - Escape to close @Mention Autocomplete Type @ followed by a name to search and mention ServiceNow users. The extension pre-fetches users from the case context (watchlist, assigned-to, caller, etc.) so relevant names appear first. Works even when opening cases by case number. Image Upload Click the image button to upload images directly as ServiceNow attachments. Images appear in the preview and are embedded in the final output. Supports drag-and-drop-style file selection with interactive image resizing. Find & Replace Built-in search with Ctrl+F — find text, replace individual occurrences or all at once, right inside the editor. Reusable Templates Save frequently used responses as templates. Templates support dynamic variables with the {{variable}} syntax — when you insert a template, you'll be prompted to fill in each variable. Track usage counts to see which templates you use most. Dynamic Signature Configure a personal signature that auto-appends to your comments and resolution notes. Supports dynamic placeholders: - {{user_name}}, {{user_first_name}}, {{user_last_name}} - {{user_email}}, {{user_title}}, {{date}} Smart duplicate detection prevents the same signature from being added twice. Draft Auto-Save Never lose your work. The composer automatically saves drafts per case with a 12-hour TTL. If you close the composer or navigate away, your draft is waiting when you come back. A timestamp shows when the draft was last saved. Field Sync Selector Choose which ServiceNow field to target: Additional Comments, Work Notes, or Resolution Notes. The extension remembers your preference across sessions. On first use, a friendly prompt helps you pick your default. Resizable Composer Need more room? Click the resize button to cycle through three sizes: - 1x (default) — standard modal - 1.5x — larger for detailed responses - 2x — near full-screen for long-form content Your preferred size is remembered across sessions. Smooth animations between all sizes. - Line wrapping for comfortable editing of long text - Full markdown syntax highlighting via CodeMirror 6 - Line numbers in the editor gutter - Automatic import of existing field content (HTML converted to markdown) - Dark mode with full theme support for editor and preview Works everywhere in ServiceNow: - Classic UI (nav_to.do URLs) - CWF Agent Workspace (Configurable Workspace Framework) - Cases opened by case number or sys_id - Shadow DOM fields in modern ServiceNow layouts - Additional Comments, Work Notes, and Resolution Notes fields The extension automatically detects your ServiceNow context using multiple strategies, so features like @mentions and draft saving work regardless of how you navigate to a case. Multiple ways to use your formatted content: - Insert to Comments — with signature (if enabled) - Insert to Work Notes — without signature - Insert to Resolution Notes — with signature (if enabled) - Insert & Copy — inserts AND copies formatted HTML to clipboard - Clear All Formatting — strips markdown to plain text Use the split button in the footer or keyboard shortcuts for fast insertion. - Dark/Light mode toggle (persists across sessions) - Signature enable/disable with custom text editor - Template management (create, edit, delete) - Field sync preference - Composer size preference - All settings saved to Chrome storage 1.
