# Unmatched Writing Experience
iA Writer is designed to provide the best digital writing experience: Keep your hands on the keyboard and your mind in the text.

# Embed Pictures, Tables and Nest Textfiles
Include images from Library in your documents (.png, .gif, .jpg)—images are uploaded to Medium and WordPress when sharing a draft. Include comma separated value files as tables in your documents (.csv), or create advanced tables using MultiMarkdown. Build a manuscript from several chapters, embed source code files as code blocks, or nest text files into each other.

Note: Embedding only works for files in the same folder (or subfolders) as the master file. You can’t embed files in a parallel or higher directory.

# Swipe Right to Library
iA Writer now comes with an integrated library for all your documents. With a swipe to the right you have easy access to all your texts in one place.

# Swipe Left to Preview
With synchronized scrolling Preview, iA Writer consciously separates form and content. It optimizes plain text writing while offering stellar formatted export—with world class typography.

# Focus Mode and Syntax Control
iA Writer is famous for offering a deeper focus on your text. Its unique tools improve your writing style by honing your concentration: One sentence at a time, or by highlighting different parts of speech.

Customer Reviews

Tried to love…and could but can’t use.

I feel bad about writing this review because I loved typing in this app.

I looked and looked at writing apps for a while; finally, I choose iA — The Focus Feature is excellent, and there is a fantastic content selection system at the bottom of the window. My one (out of three) main complaint was the navigation system (or lack of) on the left, so I wrote them; they got right back to me and said my requests were on the way — that was six months ago.

iA is clean and comfortable; it has power, but this poor navigation/organization system renders it disappointing. This app is useful for writing one page, not a book — or anything you write that has more than one page that you need titled and organized. My other negative criticism is I would like to see a button to switch between Syntax and Format (instead of a menu pull-down)— I also have enough screen real estate to display them both at once. Probably not meant for it so it’s not a big deal but the font-styling integration (is probably par for this type of app but it) is not friendly.

Sorry, iA. I have been waiting months for something you said was (quickly) coming.
I need to organize on the fly and have it replicated (exported/rathered mirrored) in the Finder. I can not do it with iA.

Really great writing app!

My requirements for my writing are pretty simple: I need an editor that uses Markdown, uses flat-files (.txt or .md, nothing proprietary), and allows me to attach photos to each file. iA Writer passes my requirements with flying colors. I only have two things on my wish list though: a better way to organize files (thinking of Ulysses and Notebooks here), and a way to change the default editor font. But these are minor things when compared to how well iA Writer meets my requirements. I also like the options at the bottom of the main editor screen, where you can toggle between Format and Syntax. Very cool. And the fact it handles tables and various kinds of lists!!! And that it works on all my devices, so I can take my writing with me wherever I am, is wonderful. Just an overall superb application. All my writing, wherever it ends up, starts in iA Writer.
