Style Check
Style Check for Android 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 (
basicfundamentals, combinetogether, falldown) - clichés (
against all odds,brass tacks,long and short of it)
For more details about Style Check, you can read this introduction blogpost: The Power of Style Check.
Enable Style Check
To enable/ disable Style Check:
- stay in the Editor mode
- tap the 3 dots on the top-right ⋮ → Style Check



You can fully enable Style Check including:
- fillers
- redundancies
- clichés
- custom (see below)
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 → Style Check → 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 Custom Patterns.


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/
