15 writing patterns that make a LinkedIn post read as AI-written
Every pattern the free Klype checker flags, one page each: what it looks like, why readers distrust it, the exact rule the checker applies, and a before-and-after rewrite.
The checker is a set of plain rules that run in your browser. Each one looks for a shape that readers have learned to associate with text produced on request: a stock opener, a percentage with no source, a tidy story with no detail only the author could know, a block of hashtags. None of the rules proves a post was generated, and a careful human draft can trip one or two. Three or more together is usually what readers are reacting to when they say a post sounds like AI.
The pages below describe each rule as it is actually written, including what it misses, so you can judge a finding rather than take it on trust. They are ordered roughly by how often readers notice each pattern.
Cliche openers
A first line built from stock phrases such as "In today's fast-paced world", "Let's dive in" or "Here's the truth" that could open any post on any topic.
Checker rule: Cliche phrasing02Unsourced statistics
A percentage or similar figure stated as fact with nothing in the post saying where it came from.
Checker rule: Figures with no source03Invented stories
A short scene, with people doing and saying things at a stated time, written as fact but with no detail that only someone who was there could know.
Checker rule: Reads like an invented story04Closing question to the reader
A final line that asks the reader something: "What do you think?", "Have you experienced this?", "Agree?"
Checker rule: Ends on a question to the reader05Hashtag block
Three or more hashtags grouped together on a line of their own, usually the last line of a post.
Checker rule: Hashtag block06Em dash overuse
The long dash (U+2014) used so often that it replaces full stops, commas and colons throughout the post.
Checker rule: Heavy em dash use07"Not just X, it's Y"
A sentence shaped as "it's not just about A, it's about B", which denies a modest claim in order to introduce a grander one.
Checker rule: "Not just X, it's Y"08Three-item lists
Runs of three single words separated by commas ("clarity, consistency, and authenticity") appearing again and again across one post.
Checker rule: Three-item lists09Flat rhythm
Sentences of nearly identical length from the first line to the last, with no very short sentence and no long one.
Checker rule: Flat rhythm10Uniform paragraphs
Every paragraph in the post is about the same size, so the draft looks like a stack of identical blocks.
Checker rule: Uniform paragraphs11Summary ending
A final paragraph that restates what the post already said, usually opening with "in short", "in summary", "ultimately" or "the bottom line".
Checker rule: Summary ending12Universal lesson ending
A closing line that turns the post into a general truth, such as "this shows that consistency matters" or "it's a reminder that simplicity wins", and that could close any post on any subject.
Checker rule: Universal lesson ending13Enumerated lessons
A post structured as "First, ... Second, ... Finally, ...", with each lesson introduced by an ordinal and a comma.
Checker rule: Enumerated lessons14Markdown asterisks
Text wrapped in double asterisks, **like this**, pasted into LinkedIn, which shows the asterisks literally instead of making the text bold.
Checker rule: Markdown asterisks15Vague result claims
An outcome asserted in words that cannot be checked, such as "engagement skyrocketed", "metrics were up" or "the results speak for themselves".
