How to check text for AI generation
Paste 600–10,000 characters into the text box, or import a plain-text .txt file. Select Analyze text to request a live scan when available. Read the overall signal alongside any passage details, then compare the result with the writing’s sources and drafting history.
An AI checker for articles, essays and other writing
Use the checker as one part of reviewing a draft, an article or an essay. Passage details can help you decide where to look more closely. They do not establish who wrote a sentence, which model was used, or whether an author broke a rule.
Can this detect ChatGPT writing?
The live service looks for signs of AI-generated writing. A result is not proof that ChatGPT, Claude, Gemini or any particular model produced the text. We have not published an independent model-by-model accuracy benchmark for this product.
What does the text score mean?
AI Checker converts the provider’s human score into an AI signal by subtracting it from 100. A signal of 80 or above is labeled likely AI-generated; 25 or below is low signal; values between them are inconclusive. These labels are product thresholds, not a calibrated probability that an author used AI.
Is this a plagiarism checker?
No. This tool looks for AI-generation signals. It does not search publications or websites for matching passages, verify quotations, or establish whether an author copied a source. Review citations separately.
What if human writing is flagged?
A false positive is possible. Review drafts, notes, cited sources and the author’s explanation rather than treating a score as evidence of misconduct. Short, edited or mixed human-and-AI writing needs particular care. Do not use this result alone to make a consequential decision about someone.
