ChatGPT Detector: Review AI-Typical Phrasing in Academic Papers
Our ChatGPT detector reviews AI-typical phrasing sentence by sentence. It does not identify the model or prove authorship. AI typicality runs from 0 to 100, with 50 neutral. Results in about 15 minutes, from $0.29/page.
This multifaceted approach enables a comprehensive understanding of the topic.
Illustrative example, not an actual report. A score is not the probability that AI wrote a passage.
ChatGPT Writing Patterns, Not a Fingerprint
PlagAware evaluates the frequency and relevance of stereotypical AI expressions in each sentence. The result measures AI-typical phrasing, not who wrote the text. The detector can miss AI-generated text and flag human writing. Model choice, prompts, editing, and subject-specific language can affect the scores. Review passages in context and follow your institution's AI policy.
Hedge Phrases
Stereotypical expressions can occur in ChatGPT output and in human text. No individual phrase proves AI use.
Uniform Sentence Rhythm
Sentence length and structure vary in both human writing and AI output. Uniform rhythm alone is not proof of AI authorship.
AI-Typical Expressions
PlagAware evaluates the frequency and relevance of stereotypical AI expressions. This is a language-pattern measure, not an authorship test.
Why Universities Are Taking ChatGPT Seriously
Traditional plagiarism detection matches text against sources. ChatGPT output may have no source match, but can also reproduce published wording. A 0% similarity score does not prove originality or rule out AI use.
AI rules differ by institution and assignment. For example, Oxford requires prior authorization for AI use in assessments. Check the rules for your course rather than relying on a detector score.
- AI output may or may not match published sources
- AI-typical phrasing analysis is separate from source matching
- Keep drafts and disclose permitted AI assistance
- Our Combo plan covers both plagiarism and AI simultaneously
"It is worth noting that this phenomenon has been studied extensively in the literature."
"In summary, the evidence suggests a clear and positive relationship between the variables."
"There are several key factors that contribute to this outcome, including economic conditions, social dynamics, and institutional frameworks."
"I'm still not sure whether the third case study supports my argument or undermines it. That's something I want to work through in the discussion chapter."

ChatGPT Pattern Analysis
PlagAware evaluates the frequency and relevance of stereotypical AI expressions in each sentence. The result measures AI-typical phrasing, not who wrote the text.
Scored Report by Email
In about 15 minutes you receive a PDF with sentence-level AI typicality scores. Red highlights indicate AI-typical phrasing, not proof of AI use. Review the context and keep your drafting evidence; changing a score does not establish compliance.
AI Models and Detection Limits
The detector assesses AI-typical phrasing rather than identifying a particular model. Detection is not guaranteed for every model, version, or edited passage. PCO has not published model-specific validation for this service.
ChatGPT / GPT-4
ChatGPT is an example of generative AI. The score does not identify an OpenAI model or version.
Claude (Anthropic)
Claude is an example of a generative model family. Detection of a particular version is not guaranteed.
Gemini, Llama & Mistral
Output from different model families can contain AI-typical phrasing. See our LLM detector for detection limits.

ChatGPT Detector: Frequently Asked Questions
No. PlagAware assesses the frequency and relevance of AI-typical expressions, which can also occur in human writing. Its 0 to 100 typicality score is not an authorship probability and cannot identify ChatGPT or a particular model.
ChatGPT can generate fluent text without a matching online source, but output can also overlap existing sources. AI use and disclosure must comply with the institution's policy; a detector cannot establish compliance.
Yes. A plagiarism checker compares your text to existing sources. An AI detector assesses AI-typical phrasing without a source match, but cannot prove authorship. Asking a chatbot to do either job is not a substitute; read can ChatGPT check for plagiarism.
PlagAware documents AI-typical expressions in ChatGPT output, including a GPT-4o mini example. It does not guarantee detection of every GPT version. A score does not identify the model used.
Yes. Students can review AI-typical phrasing before submission. The score is not proof of AI use or a prediction of your instructor's result. Keep drafts and follow your institution's disclosure rules.
