Pro Tip: All your notes are saved automatically to your browser. You can close the tab and come back anytime — your work will stay right here.
What is the Markdown Notes Editor?
The Markdown Notes editor is a dual-pane writing environment that lets you compose formatted documents using Markdown syntax and see a live rendered preview side by side. Standard note apps store your content on remote servers. This tool handles all rendering inside your browser with no server contact.
It auto-saves your notes as you type using your browser's local storage, so you can close the tab and return later without losing work. Your text and formatting choices stay private on your own device.
How to Use the Markdown Notes Editor
Writing and formatting notes involves these steps:
- Select a starting template (Daily Log, Meeting Minutes, or Project Plan) from the Template dropdown, or start writing directly.
- Type your content into the left editor pane. Use Markdown syntax: # for headers, **bold**, *italic*, and - for list items.
- Watch the Live Preview pane on the right render your formatted output in real time.
- Your notes auto-save to localStorage as you type — a green "Auto-saved" badge confirms each save.
- Click "Download .md" to save your current note as a .md file on your computer.
- Click "Clear All" to reset the editor. Confirm the dialog to prevent accidental data loss.

Yes. The exported file is a standard .md file compatible with VS Code, Obsidian, Typora, and any plain text editor.
Does this support tables or code blocks?
Yes. The Marked.js engine supports GFM features including fenced code blocks, inline code, and standard Markdown tables.
What happens if I click "Clear All"?
A confirmation dialog appears before clearing. Once confirmed, both the editor content and the localStorage entry are erased permanently.
