How does an AI detector work exactly?

AI detectors are given a set of training data that typically includes both human and AI-generated text. AI detectors use advanced machine learning algorithms to analyze and understand hidden patterns in the training text and learn to differentiate them. When a new piece of text is fed into an AI detector, it uses the patterns it learned from the training data previously to classify the current text into either AI or human.

What is the best way to avoid AI content detection?

The best way to avoid AI content detection is not to copy and paste text directly from AI tools like ChatGPT. Instead use ChatGPT like Wikipedia to get answers for questions and consume the information first, and then write them down in your own words. This will help you pass the AI content detection. Copying one or two lines from a passage generated by ChatGPT is fine provided you sufficiently paraphrase them. You can use different paraphrasing techniques to rewrite the text.

Why are some sentences in my article still flagged as plagiarized by the plagiarism checkers, despite citing all those phrases?

This normally happens due to excessive use of quotes in your paper. You should only use the exact text from someone else's work and put them in quotes if you think it is important to be precise. The recommended practice is to understand the work and then write it in your own words. This will reduce the plagiarism percentage.

Do plagiarism checkers steal your work?

It is very important that you use a reputable plagiarism checker such as Ref-n-write that does not store your uploaded documents permanently. Once the plagiarism report is generated, your document is deleted and none of the contents are retained in the system.

Can an AI detector detect contents obtained from chat GPT 3.5 and paraphrased using a paraphrasing tool?

It depends on the nature of the paraphrasing tool. If the paraphrasing tool still uses ChatGPT in the backend, then it will be picked up by AI detectors. If you use Ref-n-write’s academic proofreading and paraphrasing tools that do not use AI generated text, then there is a good chance that it might pass AI detectors. However, it depends on how much of the source text has changed, if you make minimal changes to ChatGPT text, it will still get picked up by AI content detectors.

Plagiarism checker says that I plagiarized on a paragraph but I didn't. What should I do?

If you're confident that you did not plagiarize a paragraph but the plagiarism checker is flagging it, then look at the plagiarism report carefully to study why the plagiarism checker thinks that you have plagiarized. Look that the sources that are mentioned in the report and check if you have unintentionally used similar words or phrases in your text. If that is the case, consider paraphrasing the text and modifying the content. If the problem still persists, it's best to speak with your instructor or professor directly. Explain the situation and provide evidence that you did not intentionally plagiarize.
