InfraNodus

InfraNodus visualizes text as a network: words are nodes and their co-occurrences form connections. Graph theory algorithms identify topical clusters (topic modeling), influential concepts, and structural gaps between clusters. Users can import content such as notes, PDFs, Markdown, CSVs, survey responses, Google search results, YouTube transcripts and comments, websites, RSS feeds, and Amazon reviews, then explore the graph and use built-in AI to summarize statements and generate ideas. The page also describes integrations with MCP server, n8n, Cursor, Obsidian, and a browser extension for GraphRAG and LLM workflows. It is built on a peer-reviewed method (WWW'19) and states that data is private by default and hosted in the EU. The page lists a 14-day free trial and paid plans.
