Highlight Wikipedia-sourced signals
A free Chrome extension that highlights Wikipedia-sourced AI-writing signals.
AI Writing Highlighter is a Chrome extension that highlights writing patterns associated with AI-generated text on web pages. It works on your computer, not in the cloud. It compares what you read to pattern data derived from Wikipedia editors' public Signs of AI writing page.
That page is actively maintained. Wikipedia editors add signs as they spot them in real articles and flag them for cleanup. The extension pulls a fresh copy of those patterns once a day, so what you see reflects the current public guide, not a model or private source list.
What it does
Open a news story, a LinkedIn post, a product description, or any page with text, and the extension checks it for Wikipedia-sourced AI-writing signals. Matched phrases get underlined and nearby lines get a subtle highlight. The Chrome extension shows you the pattern score.
About the number
A higher score means more guide patterns appeared in the text. It measures pattern matches, not authorship. The extension cannot tell you who wrote the page.
Why Wikipedia
The guide covers habits like hollow scene-setting openers, overused transition phrases, padding that inflates length without adding meaning, unusual synonym variation, stray markdown or chatbot disclaimers left in the text, and an unusual fondness for lists of exactly three things.
The list is not a verdict. Human writers use these phrases, and AI can avoid them. Real editors maintain it openly, revising as the habits evolve.
How it works
- The extension finds the main content on the page, ignoring menus, sidebars, and navigation.
- It scans paragraphs, headings, pull quotes, and list items.
- Each piece of text is checked against patterns curated by Wikipedia editors.
- Matched phrases get underlined without modifying the site's own code.
- Every match is tallied and weighted using the guide data, with local safety filters for overly broad entries.
- The extension shows your pattern score, source revision, and a breakdown of which categories came up most.
Private and free
The extension costs nothing. You do not sign up, there is no monthly fee, and there is no usage cap. Nothing you read gets uploaded for analysis.
Everything runs locally in your browser. The text you read never leaves your device, and nothing is sent to any external service, AI or otherwise. We do not track clicks or sell data.
- No sign-up.
- No tracking.
- No paid scans.
- No subscription.
Why it is free
Local analysis means no server costs, so there is no limit on how many pages you check. Once a day, the extension pulls updated pattern data from aiwritingguide.misterburton.com.
Updated every day
AI-writing signals shift constantly. Wikipedia editors update their page as new clichés emerge and old ones fade, and the Chrome extension pulls a fresh copy once a day from aiwritingguide.misterburton.com.
If the daily update fails, the previous version still works.
What it won't do
The score is a signal, not a verdict. Human writing can match these patterns, and AI writing can miss them. Use this resource as a starting point, not a conclusion.
