    Flags and guidance appear at the paragraph level for quick edits.

    6. Real-Time AI Probability Score

    Each scan gives you a clear AI Probability Score (%) for your text, similar to the colour-coded bars you see in a Turnitin similarity report. You can re-run the scan after editing to confirm that the AI-likelihood has dropped and that your writing now reads more naturally.

    7. Built-In Humanisation Hints

    The tool provides simple humanisation suggestions. You are guided to vary sentence rhythm, add more personal analysis, and soften automated phrasing before submission. For more complex cases, students can combine this with our Humanise AI-Written Dissertation service for a deeper review.

    8. Integrated Academic Workflow

    Premier’s AI Detector is designed for real academic use. It links naturally with our Turnitin plagiarism checker, proofreading & editing, and dissertation help services, so you can move from AI detection → editing → plagiarism check → submission without changing platforms.

    About the AI Detector Tool

    The Premier Dissertations AI Detector Tool helps students, teachers, and researchers check whether their work includes any AI-generated or AI-refined content. It is built on technology similar to Turnitin’s AI system and analyses how your sentences flow, how predictable they are, and how naturally they vary.

    When you scan your essay, report, or dissertation chapter, you receive a simple, clear label for each section, showing if the text is:

    • Human-written – natural variation and original phrasing.
    • AI-generated – likely written mainly by tools such as ChatGPT or Gemini.
    • AI-refined – human text that appears heavily rephrased or polished by AI.

    For deeper checks, you can combine this with our classic AI plagiarism checker to cross-verify originality, or review our ChatGPT & academic integrity guide to understand how universities view AI use.

    🔒 Your files are analysed securely by our system and editors, then deleted after review – nothing is uploaded to public databases.
