Paste your text on the left and click “Check patterns.” Results appear here.
HOW IT WORKS
From pasted text to clear fixes in seconds
No account and no upload. The checker reads your text in the browser and shows which patterns make it read as generic, sentence by sentence.
Paste your text
Add at least 100 words: a blog post, a product page, or a draft you want to publish. Longer text gives more reliable results.
Read your scores
See four scores for sentence rhythm, sentence length, stock phrases and first-hand detail, each with a plain explanation.
Fix the highlights
Every flagged sentence is highlighted in place, so you know exactly where to add specifics, vary rhythm or cut filler.
WHAT THE CHECKER LOOKS AT
The patterns behind an AI detector score
AI detectors give you a percentage without reasons. This checker measures the writing patterns that commonly push those scores up, and tells you what to change.
Sentence rhythm
Measures how much sentence length varies. Below 0.40, sentences are a similar length and read as mechanical. Above 0.40, the mix feels natural.
Average sentence length
Between 15 and 25 words reads comfortably online. Above 25, readers lose track. Below 12, the writing can feel choppy.
Repeated openers
Flags any two-word opening used three or more times, a common sign that text follows a template.
Stock phrases
Finds filler lines like “it’s worth noting” or “the bottom line.” One or two is normal. Three or more leans on stock language.
First-hand signals
Counts numbers, dates and first-person words like “we” or “our.” Aim for at least 1 per 100 words to show real data or experience.
Sentence-level highlights
Red marks repeated openers or stock phrases, yellow marks runs of similar-length sentences, and green marks data or first-hand detail.
PATTERN CHECKER VS AI DETECTORS
A score tells you what. Patterns tell you why.
Google does not rank content by how it was written. Its quality systems and spam policies focus on real value, so fixing thin or formulaic writing matters more than any detector score.

FAQ
AI writing and detector questions
How do AI detectors work?
Most AI detectors measure how predictable each word is and how much sentence length varies, then run the text through a classifier trained on human and AI writing. They report a confidence score, not proof of who wrote the text.
Are AI detectors accurate?
Not reliably enough to trust alone. Different detectors often give very different scores for the same text, and clear, structured human writing can be flagged as AI. Use a score as a prompt to review the text, not a verdict.
Is this an AI content detector?
No. It does not guess who wrote your text. It shows writing patterns that make content read as generic, such as uniform sentence rhythm, repeated openers, and stock phrases.
Is my text stored or sent anywhere?
No. The analysis runs entirely in your browser. Your text is never uploaded, as described in our Privacy Policy.
Does Google use AI detectors?
Google evaluates whether content is helpful and original, not how it was produced. Its scaled content abuse policy targets pages made mainly to manipulate rankings, whether written by people or AI. Publishing at scale? Check your templates for duplicate content too.
What is a good sentence rhythm score?
Above 0.40 usually means sentence lengths vary naturally. Lower scores mean many sentences have similar length, which reads as mechanical.
