How do I check if a document is AI generated?
The most reliable way to check whether a document was written by AI is to run it through an AI Detector. These tools analyze patterns in the text (like phrasing, predictability, and structure) to determine whether the content is more likely to have been written by a human or generated by AI. For the most reliable results, analyze longer passages of text rather than a single sentence, since AI detectors need enough language patterns to evaluate.
You can also review the document yourself for common signs of AI writing. AI-generated text often relies on predictable sentence structures, repetitive word choices, and a neutral or overly generic tone. While these clues can be helpful, they’re not always definitive on their own. Because no detection method is perfectly accurate, it’s best to combine automated tools with manual review.
Some tools provide additional insights. For example, QuillBot’s AI Content Detector provides a detailed analysis that distinguishes between AI-generated and AI-refined text, giving you clearer insight into how a document was likely produced. This makes it easier to evaluate the originality of content and determine whether AI tools played a role in its creation.

AI detectors analyze text for patterns that commonly appear in machine-generated writing, such as highly predictable phrasing, low variation in sentence structure (often called low “burstiness”), and other linguistic features typical of language models. They rely on machine-learning classifiers trained on large datasets of both human and AI-written content, then use those patterns to estimate […]
