Sync Google Drive Files to InfraNodus Knowledge Graph

This n8n workflow automates the synchronization of files from a specified Google Drive folder to an InfraNodus knowledge graph. It triggers on new files, iterates through them, retrieves content, identifies file types (TXT, PDF, Markdown), and extracts text accordingly. For PDFs, it offers optional high-quality conversion via ConvertAPI before processing. The extracted text is then sent to InfraNodus's graphAndStatements API to generate or update a knowledge graph.

Key benefits include automatic revelation of main topics, ideas, and content gaps in your document collection, enabling AI-powered conversations with your files. This is ideal for knowledge management, research, and content optimization, saving hours of manual analysis. The resulting graph is accessible via InfraNodus's GraphRAG API for integration into other workflows.

Use cases span education (course material organization), research (literature synthesis), and business (internal knowledge bases). It's particularly valuable for course managers handling student submissions or lecture notes, turning raw files into interactive, insightful graphs without manual intervention.

The workflow demonstrates advanced n8n features like looping, conditional logic, and multi-service integrations, making it scalable for large folders.
