Type on the left, read it on the right
Writing Markdown blind is annoying. You add a heading, second-guess whether you used two hashes or three, and don’t find out until you paste it somewhere. This editor kills that loop. The pane on the left is your raw Markdown. The pane on the right is the rendered result, updating as you type. No “preview” button to click, no tab to switch.
It’s the same setup you’d get in a static-site editor or a README tool, minus the install. Open the page, start writing, and the formatting shows up next to your text in real time.
The toolbar, and what it actually inserts
Above the editor sits a row of buttons. They don’t open menus or dialogs. Each one wraps or prefixes whatever you’ve got selected, then hands focus back so you keep typing:
- Bold and Italic wrap the selection in
**or*. Select a word, click Bold, done. - H2 drops
##at the start of the line. Select a few lines and it tags each one. - List prefixes lines with
-, so highlighting three lines turns them into three bullets. - Link wraps your text as
[text](https://)and parks the cursor so you fill in the URL. - Code and Quote handle inline backticks and
>blockquotes the same way.
Nothing here is magic. It’s just the keystrokes you’d type by hand, one click instead of remembering the syntax. If you already know Markdown cold, skip the toolbar entirely and type.
It saves while you write
Here’s the part people miss until they need it: your draft autosaves. A fraction of a second after you stop typing, the text gets written to your browser, and a small “Saved” tag flashes to confirm. Close the tab, reopen the page tomorrow, and the draft loads right back into the editor.
That save is local. The text sits in your browser’s storage on this one device and goes nowhere else. There’s no account, no server copy, no sync across machines. Clearing your browsing data wipes it, and a private window starts blank. So for anything you’d hate to lose, hit Download .md and stash the file somewhere real.
Below the editor you’ll see a running word and character count, handy when you’re keeping a description under a limit or roughly targeting a length.
Getting the output out
Two ways to leave with your work. Copy HTML runs your Markdown through the converter and drops clean HTML on your clipboard, ready to paste into a CMS, an email, or a template. Download .md saves the raw Markdown as document.md so you can commit it to a repo or open it in another editor later.
The HTML gets sanitized before it’s ever shown or copied, so a stray <script> in your source won’t render or travel with the output. Everything happens on your device. The Markdown never gets uploaded.
Questions people ask
Does my writing get sent to a server?
Nope. The rendering, the autosave, and the HTML conversion all run in your browser. Your text stays on your machine and isn’t logged anywhere.
Will my draft survive a page refresh?
Yep. It’s saved to local storage and reloads automatically, as long as it’s the same browser and you haven’t cleared your site data.
What Markdown does it support?
The common stuff: headings, bold, italic, links, images, inline code, fenced code blocks, blockquotes, unordered lists, and horizontal rules. It covers the syntax most READMEs and blog posts actually use, not every obscure extension.
Can I paste my own Markdown in?
Of course. Drop it into the left pane and it renders immediately. The toolbar and counts work on pasted text just like text you type.
Why does the copied HTML look stripped down?
The converter outputs clean, semantic tags without inline styles, and the result is sanitized to remove anything unsafe. Style it with your own CSS once it’s in place.
Is there a length limit?
Practically, no. You can write thousands of words. Browser storage caps in the multi-megabyte range, which is far more text than a typical document needs.
