Scrivener Icon

Scrivener

Scrivener takes tools familiar to writers everywhere and integrates them in new and exciting ways.

For writing. And writing. And writing.

Scrivener is the go-to app for writers of all kinds, used every day by best-selling novelists, screenwriters, non-fiction writers, students, academics, lawyers, journalists, translators and more. Scrivener won't tell you how to write—it simply provides everything you need to start writing and keep writing.

Grow your manuscript your way

Tailor-made for long writing projects, Scrivener banishes page fright by allowing you to compose your text in any order, in sections as large or small as you like. Got a great idea but don't know where it fits? Write when inspiration strikes and find its place later. Grow your manuscript organically, idea by idea.

See the forest or the trees

Whether you plan or plunge, Scrivener works your way: hammer out every last detail before typing a word, or carve out a draft and restructure later. Or mix your methods and do a bit of both. In Scrivener, everything you write is integrated into an easy-to-use project outline. So working with an overview of your manuscript is only ever a click away, and turning Chapter Four into Chapter One is as simple as drag and drop.

Research within reach

Need to refer to research? In Scrivener, your background material is always at hand, and you can open it right next to your work. Write a description based on a photograph. Transcribe an interview. Take notes about a PDF file or web page. Or check for consistency by referencing an earlier chapter alongside the one in progress.

Getting it out there

Once you're ready to share your work with the world, compile everything into a single document for printing, self-publishing, or exporting to popular formats such as Word, PDF, Final Draft or plain text. You can even share using different formatting, so that you can write in your favorite font and still satisfy those submission guidelines.

iA Writer Icon

iA Writer

Get focused. iA Writer offers a unique writing experience that lets you concentrate and clarify your message. Used by half a million people worldwide, its powerful interface is crafted to cut out noise, let you focus on what you want to say, and help you structure and trim your text. Available for Mac, iOS, Windows, and Android.

Simple and Powerful

No rulers, no formatting bars. iA Writer provides the crisp, uncluttered environment you need to write well, supported by discrete, powerful features, from Content Blocks, to Syntax Highlighting.

Focus and Flow

Focus is the key to good writing, and the guiding principle behind iA Writer. With shortcuts and simplified settings, you can keep your hands on the keyboard and your mind in the text.

Ownership and Control

We think every craftsperson should own their own tools, so when you download iA Writer, you own it. No forced subscriptions, microtransactions, or compatibility concerns. Your work, your files, your app.

Hack Your Syntax

Highlight parts of speech to improve your writing. Spot superfluous adjectives, weak verbs, and unwanted repetitions. Developers have long used syntax highlighting to improve their code. Now you can hack your text.

Power of Style Check

Style Check is like having a personal editor-in-chief on your device, carefully reviewing your text for redundancies, clichés and filler words as you type. It’s simple, different, and powerful.

The Original Focus Mode

Focus only on the sentence or paragraph that you’re working on. Introduced in 2010 with the original iA Writer, Focus Mode has since been copied by many writing apps. This is the original, and still (we think) the best.

Flexible Content Blocks

Swap sections around, add media, and construct your content with flexible building blocks of text, .csv tables and image files. Stitch separate chapters together into one master file. Express yourself through experimentation.

Optimized Typeface

We have created an innovative typeface for iA Writer, specifically designed to enhance the writing experience. The family comes in three flavors: classic Mono, Duo for larger screens, and Quattro for small devices.

Parallel PDF Preview

iA Writer now offers a live, paginated PDF preview, parallel to the text you are editing. Instantly see how your document translates into PDF pages, as you edit.
