MRMarkdown Editor
โจ What is this?
A cozy Markdown editor with a live preview, local document storage, and quick export. No sign-up, no server: everything runs in your browser.
๐ The editor
Open a doc from the dashboard, type in the left panel, and see the preview rendered in real time on the right. Use the labeled toolbar for headings, lists, links, code, and more. Save with Ctrl+S, rename docs by clicking the title, and download your work as a Markdown file. All your notes stay in your browser (localStorage)—private and yours.
โ๏ธ Split view
The editor and preview are shown side by side by default, and you can drag the divider between them to choose how much space each side gets.
๐ฏ In short
Write Markdown โ preview it live โ resize the split โ save or export your file. Simple, fast, and stays on your device.

This is awesome, thank you for making it - a much needed program. Other markdown editors I've tried were either too slow, paid, or overly complicated. I was happy to see this in my feed. Its made in good taste, simple and fast.
The only thing that bothers me is the header sizes are a bit small; the smallest header (###### header) is smaller than regular text. I think they need rebalancing to make all headers atleast larger than regular text.
I have 3 headers
Header1
Header2
Header3
For what you need so many ######?
