ChatGPT Checker: Detect ChatGPT-Written Text in Your Academic Paper
Not sure whether your paper contains AI-written content? Our checker gives you sentence-level clarity before your instructor runs their own AI detection. Results in 15 minutes · from $0.29/page.
Why Checking for ChatGPT Use Matters Academically
Universities around the world have updated their academic integrity policies. Understanding your exposure before submission is essential.
Institutional Policies Are Evolving Fast
Many universities now explicitly prohibit submitting AI-generated text as original work. Policies vary widely, but the direction is clear: undisclosed AI use is increasingly treated as misconduct.
Instructors Use Detection Tools
Academic institutions are equipping instructors with AI detection tools. Running your own check first lets you identify and address any flagged sections before they are seen by your examiner.
Better to Know Now Than Later
A proactive check takes 15 minutes and costs as little as $0.29/page. Discovering a problem after submission — or after your instructor does — is significantly more costly.
How to Use the ChatGPT Checker
Upload Your Paper
Submit your document as .docx, .pdf, or .txt. No account required. Files up to 50 MB. Your document is processed on German servers.
ChatGPT Analysis Runs
The PlagAware engine analyses each sentence for the statistical patterns of ChatGPT and other major LLMs — perplexity, burstiness, and token distributions.
Review Your Results
Within 15 minutes you receive a detailed PDF report. Every sentence is scored 25–75. High-scoring sentences are highlighted — you can revise them before submission.
What the ChatGPT Checker Score Tells You
The score scale runs from 25 (confidently human) to 75 (confidently AI-generated). This approach is more informative than a simple yes/no answer because it quantifies the strength of the AI signal.
A paper where most sentences score between 25 and 35, with one or two sentences reaching 60+, is very different from a paper where the majority of sentences score above 65. The report shows both the individual sentence scores and a summary view.
- Individual score per sentence
- Colour-coded report (red = AI, green = human)
- Document-level summary included
- PDF format, delivered to your inbox
ChatGPT checker — sample output
Human
The gap between what I expected to find and what the data showed forced me to revisit my initial assumptions.
AI
It is important to note that this phenomenon has been extensively studied in the academic literature, with researchers highlighting its multifaceted implications.
Human
Three studies contradicted each other on this point, which made writing the literature review genuinely difficult.
Mixed
The theoretical framework integrates several established models of economic behaviour to provide a comprehensive analytical structure.
What AI Models Are Detected?
The checker covers ChatGPT and all other major language models — useful if you used multiple AI tools during your writing process.
ChatGPT (GPT-3.5 & GPT-4)
The most widely used AI for academic writing. Both the free GPT-3.5 model and the premium GPT-4 model are covered with the same detection engine.
Claude, Gemini & Others
Anthropic Claude and Google Gemini are also detected. If you used any combination of AI tools, the checker analyses the resulting mix accurately.
Open-Source LLMs
Llama, Mistral and other open-source models that power many writing assistant tools are included. See our LLM detector for details.

ChatGPT Checker — Frequently Asked Questions
Upload your document to our ChatGPT checker. The system analyses every sentence for statistical patterns characteristic of ChatGPT — low perplexity, low burstiness, characteristic hedge phrases and uniform sentence structure. Each sentence receives a score from 25 (human) to 75 (AI-generated). You receive a colour-coded PDF report within 15 minutes.
Most universities now treat undisclosed use of ChatGPT to generate submitted text as academic misconduct. Even where policies are still evolving, using AI without attribution undermines the learning purpose of academic work. A ChatGPT checker helps you identify whether your paper might flag under your institution's AI detection procedures.
Minor AI assistance typically does not leave strong detectable patterns if the actual writing is yours. The ChatGPT checker scores each sentence individually, so if only minor editing was AI-assisted, those sentences are likely to stay in the ambiguous or human range. Only sentences generated by AI will score high.
Yes. Because the checker operates at the sentence level, it can identify AI content in specific sections — introduction, conclusion, literature review — even if the rest of the paper is entirely human-written. This is one of its key advantages over document-level tools.
Yes, ideally. Plagiarism checkers catch copied text from existing sources. ChatGPT checkers catch AI-generated text that does not match any existing source. They address different risks. Our Combo plan runs both simultaneously at $0.39/page — saving 33% compared to ordering separately.
