Paste your text or upload a document and the AI Detector tells you how much of it reads as AI-generated — then shows you exactly which sentences triggered that reading and why. It is built for people who need to understand a result, not just receive a number.
Most detectors give you a percentage and nothing else. This one shows its working — and gives the same answer every time you ask.
Re-check the same text and you get exactly the same result. No language model is involved, so nothing drifts between runs.
Every flagged sentence explains itself in plain English — the phrasing, rhythm or missing human markers that triggered it.
See exactly where the indicators are, so you know which parts to look at rather than guessing at a whole-document score.
Check an essay, report or assignment straight from the file. Text is extracted and analysed the same way as pasted text.
Save the full analysis — score, evidence, highlighted text and flagged sentences — as a document you can keep or share.
Analysis runs on our own infrastructure. Your writing is not sent to a third-party AI service.
Add your text directly, or upload a PDF, Word or text file.
Several independent analyses read the text — phrasing, rhythm, human markers and more.
See the score, the highlighted sentences, and the reason behind each one.
Keep the full analysis as a document, or rewrite flagged text with HumanGPT.
