Style Check

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

Important points about this feature:

• only you see words being crossed out (the strikethrough mark won’t appear in Preview or Export)
• no deletions occur unless you choose to do them
• your text stay private and on your device (not sent to an internet service for review)
• there is no AI and it doesn’t steal your texts

Style Check is currently available for English, French, and German. It will cross out:

• fillers (basically, pretty much, sort of)
• redundancies (basic fundamentals, combine together, fall down)
• clichés (against all odds, brass tacks, long and short of it)

For more details about Style Check, you can read our introduction blog post The Power of Style Check or check our quick tour on YouTube:

Enable Style Check

You can enable/ disable Style Check from:

• the Menu Bar Focus → Enable/ Disable Style Check
• the shortcut ⌥⇧⌘D
• the Navigation Bar

You can fully enable Style Check (including fillers, redundancies, clichés, and custom patterns) or just some of them:

We spent a lot of time developing this feature and we are still improving it regularly.

However, our users might feel the need to customize Style Check regarding their own writing style. This is where Custom Patterns shines.

Custom Patterns

Custom patterns allow you to create exceptions or new rules to Style Check, to better fit your style. To create a custom pattern, go to Settings → Editor → Custom Patterns

Below is an example of when adding an exception allowing the filler “as well as”:

Custom Patterns Syntax

For your information, here is the syntax for customizing Style Check with Custom Patterns. You won’t need to remember it as you can find all of these in the Help Section of iA Writer.

Add a Rule

filler
custom ~~filler~~

Provide an Exception

Exceptions affect both custom and built-in patterns.

-filler
-custom ~~filler~~ exception

Regular Expressions

You can use regular expressions by enclosing a pattern in slashes:

/custom ~~filler~~ reg(exp?|ular expression)/
-/reg(exp?|ular expression) exception/
