It depends on how large the overlap is. I certainly would not copy it directly, and I would not include any tables or figures that were in the earlier article.

Using or copying a part of your previous paper can potentially be considered plagiarism, depending on how it is done and the context. Plagiarism involves presenting someone else's work, ideas, or words as your own without proper attribution.
Here are a few scenarios to consider:
Self-Plagiarism: If you copy and paste a significant portion of your own previous paper without indicating that it is a direct reuse, this could be considered self-plagiarism. It's generally expected that you create new and original work for each assignment or publication.
Proper Attribution: If you use a small portion of your previous paper and clearly indicate that it's a quote from your own work and provide proper citation, it's less likely to be considered plagiarism. However, even in this case, it's essential to ensure that the reused content is relevant and appropriate for the new context.
Paraphrasing and Rewriting: If you paraphrase or rewrite a section of your previous paper without proper citation, it can still be considered plagiarism. Paraphrasing involves expressing the ideas in your own words while maintaining the original meaning, but you still need to attribute the source.
Context Matters: The context of the reuse matters. If you're repurposing part of your previous paper for a new assignment or publication in a way that is relevant and adds value to the new work, it's less likely to be considered plagiarism. However, simply copying and pasting without proper citation can still be problematic.
To avoid potential issues with plagiarism, it's best to err on the side of caution and be transparent about the reuse of any content from your previous papers. If you're unsure whether your intended use might be considered plagiarism, consult your instructor, advisor, or the guidelines provided by the institution or publisher. Always make sure to give proper credit to any sources, including your own previous work.
Technically, AI-generated content is not plagiarism. Plagiarism, by definition, refers to copying other people’s content, whether you copy an article word for word or paraphrase it, to avoid detection.
Merriam-Webster defines plagiarism as taking someone else’s ideas or words and presenting them as one’s own. Since artificial intelligence tools generate unique content from scratch instead of stealing someone’s ideas, using an AI tool isn’t technically plagiarism, unlike copy-paste plagiarism.
