About this check
What AI Text Detector actually does.
The AI Text Detector — also called an AI writing detector or ChatGPT detector — evaluates writing for two distinct risks at once: whether it was likely produced by a large language model like ChatGPT, Claude, or Gemini, and whether it carries scam, phishing, or impersonation markers. Paste an essay, an email, a DM, or any text sample to receive a Truth Score with the specific patterns that triggered concern.
How it works
- 1Sentence-rhythm analysis catches the smooth, evenly-balanced cadence common in LLM output.
- 2Vocabulary fingerprinting looks for generic transitions and over-hedged phrasing.
- 3Risk-intent scoring weights urgency words, credential requests, and impersonation cues.
When to use it
Real situations this page is built for.
- An essay was submitted that may have been written by ChatGPT.
- A bank-style email is asking you to verify your password.
- A DM offer reads suspiciously polished and pressuring.
Limitations
Short samples under 50 words give weak signals, and skilled human writers who imitate LLM style can produce false positives.

Honest scope
What this detector does not do.
Naming the gaps explicitly so the score is interpreted in context.
- Plagiarism against published sources (use a plagiarism checker for that).
- Whether claims in the text are factually true.
- Authorship attribution to a specific human writer.
FAQ
AI Text Detector questions
Can a teacher use this to grade?
No detector is reliable enough to be used as a sole basis for grading. Treat results as one input alongside drafting history and conversation with the student.
Does it work in languages other than English?
The demo is tuned for English. Other languages will produce less reliable scores.
Why did a hand-written essay score as AI?
Formal, evenly structured writing — common in academic English — overlaps with LLM patterns. Add personal voice, examples, and specific claims to differentiate.
