Does using AI in a paper count as plagiarism?
Plagiarism and AI use are separate issues. Many journals and universities require disclosure rather than banning AI outright, and most prohibit listing AI as an author. Rules vary by institution, so check the specific journal or school policy before submitting.
How do I avoid being flagged by AI detectors?
AI detectors have high false-positive rates and regularly flag human writing. Rather than trying to evade them, disclose your use honestly and make sure the substance is your own analysis and evidence. Keeping a draft history gives you something to point to if the work is challenged.
