Is using AI plagiarism? It depends on the paper
Short answer
Using AI is not plagiarism in itself. Presenting AI-generated words or ideas as your own, in an assessment that does not allow it or without the acknowledgement it requires, usually is treated as misconduct, often under plagiarism or falsification rules. Whether a given use is allowed depends on the assessment, so the answer changes paper by paper.
Plagiarism versus unauthorised AI use
Plagiarism is usually defined as presenting someone else's words or ideas as your own. The University of North Carolina's definition, quoted by its Writing Center, is the "deliberate or reckless representation of another's words, thoughts, or ideas as one's own without attribution". "Reckless" matters: not knowing the rule is not a defence.
AI text is not written by a person, so universities have had to decide how to treat it. UCL's guidance is one clear answer: misuse of generative AI in assessment is considered under plagiarism or falsification, not contract cheating, and students must acknowledge use rather than cite the tool as an author. Other universities have created a separate category of unauthorised AI use. The result is similar: undisclosed or disallowed use is misconduct.
Paper by paper
The same tool can be fine on one paper and misconduct on another. This matrix shows how the risk usually differs by paper type. It is a general guide written for this site, not a rule: your assessment brief decides.
| Paper | Usually lower risk, if allowed | Usually treated as misconduct |
|---|---|---|
| Essay | Questions about your outline; feedback on clarity | Generated paragraphs presented as yours |
| Literature review | Search terms; summaries of papers you read | Citing sources you have not read; generated synthesis |
| Book review | An overview before reading | Reviewing from a summary; summary wording as yours |
| Case analysis | Organising the facts of the case | A generated diagnosis or recommendation |
| Dissertation | Planning; language checks within policy | Generated chapters, analysis or discussion |
| Admission essay | Brainstorming; readability checks | Any generated statement text |
| Exam or class test | Revision before the exam | Any use during it |

What policies usually allow
Most university policies now sit somewhere on a scale. UCL's three categories are typical: no AI use (common for exams and vivas); AI in an assistive role, where the student remains the author, with examples such as proofreading, reviewing tone, tutoring and feedback; and AI as an integral part of the task. The Russell Group's principles, agreed by its 24 universities in 2023, commit them to clear and transparent policies and to letting students ask about specific cases openly.
Two patterns hold across most policies: if AI is allowed, you usually have to acknowledge how you used it, and AI-generated sources or facts are your responsibility. Paraphrasing tools sit in a grey area covered in paraphrasing, quoting and AI rewriting.
When you are unsure
- Read the assessment brief and the module handbook for any AI rule.
- Read the university policy; how to read your university's AI policy shows what to look for.
- If it is still unclear, ask your tutor in writing before you use the tool.
- If you used a tool, keep a record and acknowledge it as required.

FAQ
Is using ChatGPT plagiarism?
Not automatically. Presenting its output as your own work, where that is not allowed or not acknowledged, is usually treated as plagiarism or a related offence.
Do I have to cite ChatGPT?
Policies differ. Some ask you to cite it in a set style; others, such as UCL, ask you to acknowledge how you used it rather than cite it as an author.
Is AI-paraphrased text plagiarism?
If it paraphrases a source, you still need to cite the source, and a paraphrasing tool may count as unauthorised AI use. Check your policy.
Can I be penalised if I did not know the rule?
Often yes. Many definitions of plagiarism include reckless as well as deliberate misuse, so check before you use a tool.
Is it plagiarism to use AI for ideas?
Using a tool to brainstorm is not plagiarism in itself, where your course allows it. If an idea or wording from the tool ends up in your work, acknowledge it as your course requires.
This guide explains common rules; your institution's policy decides what is allowed on your work.
