Lorem Ipsum

In publishing and graphic design, placeholder text is commonly used to demonstrate the elements of a document or visual presentation, such as font, typography, and layout. Even though using "lorem ipsum" often arouses curiosity because of its resemblance to classical Latin, it is not intended to have meaning. Where text is visible in a document, people tend to focus on the textual content rather than upon overall presentation, so publishers use lorem ipsum when displaying a typeface or design elements and page layout in order to direct the focus to the publication style and not the meaning of the text.

But, aren't there already a lot of Lipsum generators out there?

Yes, there are quite a few. Here are some examples:

• Lipsum.com
• Loremipsum.net
• Lorizzle
• Fillerati
• Blind Text Generator
• Lorem Ipsum on Wikisource

However, all of these lack features, or are too limited:

• Customization: Most generators only output paragraphs of about the same length. Sometimes you need lists, headings, long paragraphs, short paragraphs, etc. The website/magazine that you're designing probably isn't going to be filled with uniform paragraphs, so your placeholder text should reflect that.
• API: Loripsum.net has an API to generate placeholder text to insert it in whatever software/webapp you want. See below for details.
• The same results, all the time: Most generators output the same results, every time you request some text. Loripsum.net uses the full text of Cicero's "De finibus bonorum et malorum" to make sure you get a different placeholder text every single time.
