Introduction
Every personal statement submitted through UCAS is run through similarity detection software that compares it against previously submitted statements, websites, and published material. If similarities are flagged, the universities you’ve applied to are notified, along with a report highlighting the sections of concern. What happens next is up to each institution, but it can range from being contacted to explain yourself, to having an offer withdrawn.
When you submit your application, you now have to formally declare that your personal statement hasn’t been copied or generated by another source, including AI. UCAS is direct about this: if you generate and submit all or a large part of your personal statement using an AI tool, it could be considered cheating, and could cost you an offer.
There’s also a practical risk: because AI tools are trained on existing online material, AI-generated text is statistically more likely to be flagged as similar to other statements. The more students use AI to write their statements, the more detectable those statements become.
What Universities Are Saying
Universities across the UK have started publishing their own guidance, and the message is broadly consistent.
Cambridge is a signatory of the Russell Group’s principles on AI in higher education. Its admissions guidance permits using AI as a prompt for ideas or to assist with research, but flags two specific risks: AI can hallucinate, producing false information that, if included in your statement, would be treated as application fraud. It can also produce weak, generic output that actively reduces your chances. Cambridge also prohibits any use of AI tools during interviews, where checks are carried out.
Imperial Business School is frank about what they’re looking for and what AI costs you: an AI-generated application loses the individuality that makes a candidate stand out. Imperial actively looks for unique thinkers who can articulate their own goals, and has introduced new methods to detect AI-generated content across written statements, video interviews, and scholarship submissions.
Newcastle University puts it simply: the short answer is no. Using AI to write your personal statement significantly increases the risk of similarity flagging, and more importantly, it removes the thing admissions teams are actually trying to find – your voice, your experiences, your reasons for applying to this specific course.
City, University of London points to a secondary risk that’s easy to overlook: AI tools may be drawing on unverified or outdated sources, which is especially important given the changes to the personal statement format for 2026 entry. Guidance on what makes a good statement needs to come from UCAS and university websites, not a chatbot.
What Changed for 2026 entry
UCAS has replaced the single open-ended personal statement with three structured questions covering motivation, academic preparation, and experiences outside education, within a combined 4,000 character limit. UCAS’s own AI guidance applies to this new format: the same rules around authenticity, similarity detection, and the risks of AI-generated content hold, and each answer must be in your own words.
Conclusion
AI can be a useful tool in the application process for research, brainstorming, structuring your thinking, and checking grammar. But your personal statement is personal. Universities are trying to understand who you are, why you want to study this subject, and what you’ll bring to their campus. No AI tool has your experiences, your reasons, or your voice.
If you’re applying for 2027 entry, now is the time to start. The UCAS application portal is open, though completed applications cannot be submitted to universities until 1 September 2026. The early deadline for Oxford, Cambridge, Medicine, Dentistry, and Veterinary Science is 15 October 2026, and the main equal consideration deadline for all other undergraduate courses is 13 January 2027. Use this time well!
