Is It AI? (isitai.co.uk) is a UK-based AI detector designed for teachers and students. Unlike AI detectors that only provide a percentage score, Is It AI? highlights specific passages that triggered detection and explains why each was flagged in plain English. The tool combines AI-powered analysis with statistical pattern detection to identify sentence uniformity, vocabulary patterns, and structural markers common in AI-generated text. Student work is never stored, content is processed in real-time and immediately discarded. Built by Paul Byrne, a digital marketing strategist with 20+ years of experience including roles at Google and MediaCom, Is It AI? publishes exactly what is processed where on its school data-protection page and is designed primarily for UK education, though it works for any English-language content.

Common questions
Is this proof that someone used AI?
No. AI detection is probabilistic, not definitive. Use results as one signal to inform your judgment, alongside other evidence like writing history and conversations.
Do you store the text I submit?
No. Content is processed in real time and immediately discarded. Student work is never stored on our servers, not even a preview; our school data-protection page sets out exactly what is processed where.
Which AI models can you detect?
We test against the current versions of ChatGPT, Claude and Gemini, and publish per-model results on our methodology page. Other models share many of the same writing patterns, but we only claim what we have measured.
Why use multiple detectors?
The result comes from a trained model that combines a language-model reading of the text with local statistical measurements and a phrase library. The layers are inputs to one decision, not votes, and we publish the measured false-positive rate behind it.
Can this flag genuine student writing?
Yes, false positives can happen. This is why we show the AI-pattern score openly and emphasise that results should support judgment, not replace it.
