How it Works

To see how fast Liquid makes you, first consider how you currently perform a basic text operation such as looking text up in Wikipedia (or  any online resource).
First you select the text you want to work with, then:

Lorem ipsum dolor sit amet, sapien platea morbi dolor lacus nunc, nunc ullamcorper. Felis aliquet egestas vitae, nibh ante quis quis dolor sed mauris. Erat lectus sem ut lobortis, adipiscing ligula eleifend, sodales fringilla mattis dui nullam. Ac massa aliquet.

Standard Interaction:
Copy the text
Go to your web browser
Click on the location bar or cmd-l
Type in the URL
Hit enter
Locate the search field on Wikipedia
Click for focus
Paste the text
Hit enter

The Liquid Way:
Keyboard shortcut
Type two characters

in Detail

In detail: Let's say you select the text 'Liquid seriously speeds up your workflow'. You first need to do the keyboard shortcut to summon Liquid (by default @  but it's easily customizable to space) and Liquid opens with your text copied across, ready for action:
You can now click on menu categories (such as 'References'), or for more speed use the keyboard shortcuts which are indicated next to the commands: For example next to References you'll see (R) and once 'r' is activated you can do (W) which is the shortcut for Wikipedia, as will be shown to the right of Wikipedia.

Magic Margins

When you start writing it can be helpful to be able to note keywords where you work but which you don't know where will fit into the document quite yet. To use the Magic Margins, make sure you are in full-screen and simply double click anywhere in the margin to jot down a note or put an important keyword.

Note: These margins do not follow your document when you scroll, they are separate, to allow you to have an always-available space to jot notes.

If you would like more space to group and connect thoughts, you can click at the bottom of the document or cmd-d to enter the Dynamic View:

Dynamic View

In the Dynamic View you can think freely–without being constrained by the traditional columns of text–though the text is still connected to your Word Processing View:

Any text in this view which is also in the Word Processor View will have a blue selection rectangle (otherwise it will be orange). Double-click it and you will get a list of all the sentences in the Word Processor View which has that text (exactly the same as doing Find). Click on a sentence to jump to it or click in the margin to dismiss.

You can double-click on the other (orange) text to choose for it to be automatically appended at the end of your Word Processing View so that you can immediately start typing to elaborate on it.

Instant Outline View

Author gives you control over how you see your document by letting you cmd- to fold your document into an outline, so you always have an overview of your work. Click on a heading to jump to it or cmd- again to fold further or cmd+ to expand.

Headings are assigned by selecting text and using the keyboard shortcuts cmd-1 through 6. To go back to regular view click on a heading to jump to it, ESC or pinch back out.

This folded view shows names, highlighted and bold text to make it easier & faster to ‘jump around’ your document.

Instant Lookup & Search

To interact with the text in Author and all the text in your macOS applications, you can download the companion utility ‘Liquid’. When it is installed it you can select any text and either use a keyboard shortcut of your preference or ctrl-click and choose ‘Liquid | Flow’ and choose a command.

It is worth getting used to since it will allow you to search, look anything up, convert translate and more so quickly that when you use another computer your hands will feel like they are working in slow motion.

Most commands in Author are available through keyboard shortcuts and you can quickly learn any new commands since when you ctrl-click the keyboard shortcuts are clearly listed, something you will soon find useful and wonder why is not standard.


Everything you Cut (but not Copied) is remembered by Author. Cmd-shift-v to see what you have cut and choose what to paste.


When you are done it's time to share with the world. When you Export, Author (optionally) automatically:

  • Adds a Cover Page based on your personal details (stored from last use)
  • Formats the Citations inside the document with [(brackets)] or superscript1
  • Appends a References/ Bibliography section at the back of the document
  • Appends Visual-Meta information at the end of the document for use by Liquid | Reader and other compatible systems

Formats include:

  • .pdf
  • .doc
  • .rtfd
  • .txt plain text
  • .liquid (native Author document)
  • Print to Paper

Publish to WordPress

You can Publish to your WordPress blog, including adding tags and uploading pictures.

What People Are Saying

“Liquid | Author secretly puts all of the features you need from a writing package within reach while letting you focus on being creative” iCreate

“Words and language distinguished the human species from most if not all others. Words help us think. Liquid | Author is a new tool in the Engelbart tradition that clears away the fixation of most text editors on format and concentrates on content and composition. Authors experience a new intimacy with the semantics and structure of what they are writing. All of this improves clarity with an economy that is awesome in its simplicity and power”

On the addition of Magic Margins: “This new release of Author brings a remarkable new flexibility - marginal notes. Imagine composing using this new tool - jot ideas down in the margins for later expansion, with full capability of Author in these privileged spaces!” Vint Cerf (co-inventor of the Internet)

“Remarkable” Ted Nelson (coined the term ‘Hypertext’)

“Of all the modern, minimalist editors which I have tried, Liquid | Author is by far the best ... It has some truly innovative features, and is wonderfully designed” THE ECLECTIC LIGHT COMPANY

“Author leads the field of writing environments centred on content, rather than distracting with dozens of superfluous formatting controls. Magic Margins are another valuable tool which we all use on paper, now provided in Author. The best just gets better, whether you're writing an academic paper or a blog article.” Howard Oakley

“Wow! I really didn't think I could find anything that could replace word or open office but I did! I love the features that Author has. The Dynamic view is so helpful, laying it out as a mind map -- I love this tool and I like Author so much I decided to try Liquid Flow and Liquid reader.. so impressive. Truly unique and super powerful and you made it so easy to use -- I love this WP... Bought because you mentioned Ted Nelson. Best minimalist app ever. The features are very good for writing. The environment is very clean and minimalist and it lets you focus on what you have to do. The support team is very responsive when you have a problem. The best app for writing.
