woofmark
A modular, progressive, and beautiful Markdown and HTML editor. Markdown lets you produce rich HTML-formatted text by writing plain text. You can write code, text in italics or give them a “bolder” format. You can create headings by prefixing them with one or more hash characters (#). The less hashes they have, the more prominent your headings become. Creating links is merely a matter of wrapping some text in brackets and referencing a resource locator, like the ones you’ll find at the bottom of this text. Images can be embedded just the same, except you’ll have to prefix the wrapped text with an exclamation mark. The buttons provided look kind of rough, but that's on purpose, it's up to you to style them and the API helps you do that. Small and focused, progressive, enhance a raw textarea. Markdown, HTML, and WYSIWYG input modes. Text selection persists even across input modes! Built in undo and redo. Entirely customizable styles.

Squire
Squire is an HTML5 rich text editor, which provides powerful cross-browser normalisation, whilst being supremely lightweight and flexible. It is built for the present and the future, and as such does not support truly ancient browsers. It should work fine back to around Opera 10, Firefox 3.5, Safari 4, Chrome 9 and IE8. Unlike other HTML5 rich text editors, Squire was written as a component for writing documents (emails, essays, etc.), not doing wysiwyg websites. If you are looking for support for inserting form controls or flash components or the like, you'll need to look elsewhere. However for many purposes, Squire may be just what you need, providing the power without the bloat.
