The next-generation desktop-rich content editor that saves documents with themes. HTML & Markdown compatible. For Windows, OS X & Linux. The main idea of (Un)colored is to focus on what you write. There are no distracting elements like multiple indicators & toolbars. When you're writing, the only things you see are your content, the caret, and your cursor. The toolbar appears when you select a portion of text, documents tabs & main menu when you move your cursor at the top of the window. Simple as that. (Un)colored includes classic & standard word processor tools like Bold, Italic, Links, etc., but also Web-oriented tools like videos from YouTube, Vimeo, Dailymotion, and even Twitch livestreams. You can even include any type of embed content to your documents like SoundCloud tracks, Facebook posts, etc. thanks to the Embed Content tool.

Library which converts HTML to Markdown for your sanity and convenience. You have an existing HTML document that needs to be edited by people with good taste. You want to store new content in HTML format but edit it as Markdown. You want to convert HTML email to plain text email. You know a guy who's been converting HTML to Markdown for years, and now he can speak Elvish. You'd quite like to be able to speak Elvish. You just really like Markdown. By default, HTML To Markdown preserves HTML tags without Markdown equivalents, like span and div. To strip HTML tags that don't have a Markdown equivalent while preserving the content inside them, set strip_tags to true.

Crowbook's aim is to allow you to write a book in Markdown without worrying about formatting or typography and let the program generate HTML, PDF and EPUB output for you. Its focus is novels and fiction, and the default settings should (hopefully) generate readable books with correct typography without requiring you to worry about it. To see what Crowbook's output looks like, you can read the Crowbook guide rendered in HTML, PDF or EPUB. Crowbook will parse this file and generate HTML, EPUB, and/or PDF output formats, according to the settings in the configuration file. Crowbook supports HTML, PDF and EPUB (either version 2 or 3) as output formats. See the Crowbook User Guide rendered in HTML, EPUB and PDF. Crowbook uses pulldown-cmark and thus should support most of CommonMark Markdown.
