    Essay Guard — AI Plagiarism Detection for Moodle Essay Submissions

    Plagiarism and AI-generated submissions are a growing integrity challenge in VET assessment. Essay Guard integrates directly with Moodle to check every essay submission for plagiarism and AI-generated content before it reaches your assessors.

    The rise of generative AI tools has fundamentally changed academic integrity in VET. Students can now submit AI-written essays that pass a quick read but were never actually composed by the student. Simultaneously, traditional copy-paste plagiarism remains a persistent problem in online delivery. Essay Guard integrates directly into Moodle's assignment submission workflow, automatically scanning every essay for both traditional plagiarism (against web sources, databases, and previously submitted work) and AI-generated content patterns — before the submission reaches an assessor.

    Why your RTO needs this

    For RTOs, the stakes of undetected plagiarism are significant: you may be issuing qualifications to students who haven't actually demonstrated the required competency. ASQA's Standards require assessment to be valid and reliable — and if assessments can be gamed by AI tools, validity is compromised. Essay Guard gives your assessors the context they need to make informed decisions: a percentage similarity score, a highlighted source match report, and an AI-content probability score — all attached directly to the Moodle submission record.

    Key Features

    Web & Database Plagiarism Checking

    Submissions are checked against billions of web pages, academic databases, and previously submitted work at your RTO — identifying copied content with source links.

    AI Content Detection

    Advanced analysis identifies text patterns characteristic of AI-generated writing, scoring submissions with a probability percentage.

    Highlighted Similarity Reports

    Every flagged submission includes a colour-coded report showing exactly which phrases match external sources — with direct links to the originals.

    Assessor Workflow Integration

    Plagiarism scores and reports appear directly in the Moodle grading interface — assessors see results without leaving the marking screen.

    Configurable Thresholds

    Set institution-specific similarity thresholds for automatic flagging. Legitimate citations and reference formatting are excluded from the similarity score.
