Since ChatGPT launched, UK universities have rapidly updated their academic integrity policies. Most now run submitted work through AI detection software, the same technology we use in the Premier Check report to flag content that shows statistical patterns of AI generation.
Important: ChatGPT-generated text is not plagiarism in the traditional sense. It won't match existing sources. But AI detection tools analyse writing patterns and can flag AI content even when it appears original. This is why checking for both AI generation and similarity is now standard practice.

📊 AI Report Checker — Same Technology as Turnitin
When you submit to a UK university, your work is likely checked by Turnitin's integrated AI and similarity detection. Our Premier Check report uses the same underlying detection technology, so you can see exactly what your instructor will see before you submit. This is especially critical for reports, research papers, and journal submissions where originality is paramount.
