InfraNodus is a text-analysis and knowledge-graph platform for researchers, writers, consultants and marketing teams. It turns documents and collections of ideas into interactive networks to reveal themes, influential concepts and gaps worth investigating.
What it does Import notes, PDFs, CSVs, websites, search results and survey responses. Explore topical clusters and source excerpts, compare ideas, and use AI to develop summaries or research questions. Browser and Obsidian extensions connect existing material; API, MCP and n8n integrations bring graphs into AI workflows. It is an analytical aid, not proof that an AI-generated conclusion is correct. The company says hosted data stays in the EU.
