About Markdown Editor
A Markdown editor lets you write with simple symbols and see the formatted result at once. Type Markdown in the left box and the preview on the right updates as you type, and you can download the text as a .md file. It is free, needs no sign-up and runs in your browser, so nothing you enter is uploaded.
The preview supports the core of Markdown: headings from # to ######, **bold**, *italic*, ~~strikethrough~~, `inline code`, links, bullet lists, numbered lists, block quotes and paragraphs. A single line break inside a paragraph is kept as a line break.
It is a deliberately small set. Tables, fenced code blocks, images, nested lists and horizontal rules are not rendered, and italic uses single asterisks only, not underscores. Links must start with http, https or mailto, and any HTML you type is shown as text, not run. If you need those extras, check the result in the place you will publish it.
Your Markdown is saved in this browser as you type, separately from the other modes, and Find and Replace is above the box. Nothing is uploaded.
How to use Markdown Editor
- Choose a mode: rich text (this page), Online Notepad for plain text, or Markdown Editor for Markdown with a preview.
- Type or paste your text. It is saved in this browser automatically, so a refresh or a closed tab does not lose it.
- In rich text, select words and use the toolbar for bold, italic, underline, strikethrough, headings, quotes, lists, links, undo and redo.
- In the notepad and Markdown modes, use Find and Replace above the box to change a word everywhere, with an optional Match case.
- Use the Download button to save a file, or View HTML in rich text to copy the markup. Clear empties the editor.

Privacy: how it works
- The editor runs in your browser tab. What you write is not sent to Ulkaa or to any other server.
- Your text is saved in your browser local storage, which is how the autosave works. It stays on your device, and it is only there for this browser and this site. Press Clear, or clear site data, to remove it. Anyone with access to your browser profile can read it, so do not leave private notes on a shared computer.
Tips
- Download a copy of anything important. Autosave is a convenience, not a backup.
- Use Clear formatting after pasting from a web page or a Word file to drop styles you do not want.
- Use Find and Replace with Match case on when a word differs only by capitals, such as "US" and "us".
- Keep each mode for one purpose, so you always know where a note is.
