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? is GDPR compliant and 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. We are GDPR compliant.
Which AI models can you detect?
Our multi-model approach detects content from ChatGPT (GPT-3.5, GPT-4), Claude, Gemini, LLaMA, and other major language models.
Why use multiple detectors?
Each detector uses different techniques. By combining several models, we reduce false positives and give more reliable results. When all models agree, confidence is high.
Can this flag genuine student writing?
Yes, false positives can happen. This is why we show clear confidence scores and emphasise that results should support judgment, not replace it.
