AI Detection and ChatGPT in UCAS Personal Statements
2026 has been the first year that universities have openly addressed the problem of AI in admissions. Now, UCAS and universities are employing a wider range of detection tools to combat AI use in applications.
The all-important UCAS personal statement is now particularly scrutinised. The UCAS board itself has now confirmed that personal statements generated by AI can be dealt with in the same way as plagiarism or fraud. In other words, if your personal statement is flagged as AI-generated, it could damage your application.
For many students, AI tools are a part of everyday life. And so, the increasing use of AI detection in university admissions can make applicants anxious. However, the bottom line is that AI tools still produce bland personal statements that offer little originality. The risks far outweigh any benefits, and authenticity remains the safest approach. This is why we ensure that every personal statement is absolutely AI-free, written 100% by real humans.
Can Universities Detect AI Use in Personal Statements?
UCAS now uses a range of tools to judge whether a personal statement is written by AI or a real applicant. These include software (plagiarism tools and AI-pattern detection) and human judgement.
UCAS’s screening system compares every personal statement to those previously submitted. When content appears to be duplicated or machine-generated, it is flagged for review.
At this point, UCAS will notify every university listed on the application, who can decide to request clarification, investigate further themselves, and in some cases, withdraw their offer.
This process is identical for all students, whether UK or international. However, for international students with time-sensitive offers or visa application deadlines, the delays caused by AI flagging may have wider, more significant consequences.
Are Online AI Checkers Reliable?
AI detection software is much more advanced than it used to be. But it’s important to remember that many AI detection tools are still unreliable and inaccurate. Online AI checkers are less sophisticated than those used by universities, as they use outdated software.
Most AI detectors rely on probabilistic language analysis. This means that they identify repetition patterns of words or sentence structure. As a result, they can easily misidentify human writing if it is highly polished, or written or edited by a professional.
A high AI score does not necessarily prove that a personal statement was written by ChatGPT. Rather, it flags that it has identified languages patterns similar to ChatGPT’s.
Universities are aware of these issues surrounding AI detection. This is why they implement a range of different checks through official UCAS screening, contextual reading and judgement of academic professionals.
The Risks of Using ChatGPT in Your UCAS Admission
AI tools are tempting because they produce fluent paragraphs written in perfect standard English. However, what they cannot do is provide genuine reflections or specific understanding. A hallmark of an AI-generated personal statement is that it provides a brilliantly polished text, but with very little substance, specific examples or individuality.
There are further risks to using AI. It often uses generic claims without concrete examples, which can make your statement uninteresting and unspecific. Most worryingly, AI can “hallucinate”, inventing facts, claims, names, books or explanations that do not actually exist.
Finally, it is crucial to recognise that an AI-written personal statement is not original, and may be derived from others’ material, putting you at risk of plagiarism or duplication. This is because apps like ChatGPT use users’ data to train their model, which means that the piece of writing it produces for you may be based on what it has learnt from previous personal statements.
Particularly for applications to the most competitive universities and courses (medicine, law, Oxbridge, Russel Group), it is crucial that your personal statement presents your genuine interests and experiences. This is all the more important for universities which require interviews: if your personal statement does not align with the rest of your academic profile or self-presentation, there is further risk of it being flagged for AI use.

Authenticity is a Competitive Advantage
AI can be a productive tool for students, helping with brainstorming, grammar correction or translations. However, the crucial thing to remember is that it still cannot produce original writing that matches human reasoning or personal experience.
What is more, there are significant risks involved with producing personal statements with AI. Universities can recognise the difference, and admissions tutors consistently prefer writing that demonstrates reflective thinking and genuine interest. An AI-written personal statement can damage your changes of a successful application. It is simply not worth the risk to your future educational goals.
The safest approach is to submit a statement written by real people, refined through human expertise rather than automated tools.
In the current admissions environment, authenticity is a real competitive advantage.
