What this page helps you check
This page is tuned for the intent behind "detect GPT-4 content". It checks whether text has signals commonly seen in highly polished AI-generated writing.
You get a probability score that helps flag suspicious passages for deeper review.
How to use it in real work
Paste one coherent section at a time so the score reflects one writing style.
Compare several sections and look for consistency before drawing conclusions.
Example: an editor can test the intro and conclusion of a client draft to see if tone and signals line up.
What to keep in mind
No tool can confirm a model with 100% certainty from text alone.
Very short or heavily edited text can produce unstable results.
Practical next steps
Treat high scores as a prompt for verification, not a verdict.
Check citations, factual grounding, and the writer's process.
