AI-Powered Multi-Modal Plagiarism Detection Workflow

Transform your content integrity checking with this comprehensive AI-powered plagiarism detection workflow that processes documents, audio recordings, and images through specialized agents. Perfect for educators, academic institutions, and compliance teams who need scalable, multi-modal plagiarism detection beyond basic text matching.

What this workflow does

This automated n8n workflow receives submissions via webhook and processes them through parallel AI analysis channels. PDF and DOCX documents undergo text extraction, audio files are transcribed using OpenAI Whisper, and images are analyzed through OCR technology. All extracted content is normalized and stored in a vector database using OpenAI Embeddings for semantic retrieval.

Four specialized AI agents run concurrently: Text Similarity Agent identifies matching content patterns, Code Analysis Agent detects programming plagiarism, Multi-Modal Agent cross-references content across different formats, and Audio Analysis Agent examines transcribed speech. A final Reasoning & Aggregation agent synthesizes all findings into a comprehensive, structured report with evidence-based integrity assessments.

Use cases

• Academic institutions checking student submissions across multiple content types
• Corporate compliance teams verifying original research and documentation
• Publishing houses reviewing multi-format manuscript submissions
• Training organizations validating assessment materials and presentations
• Content review teams analyzing mixed-media submissions for originality

Technical details
