InfraNodus
Text analysis tool that maps any text as a knowledge graph to show topic clusters and the gaps between them.
InfraNodus is a text analysis tool that represents notes, documents, search results or reviews as a network graph of connected words. InfraNodus applies graph algorithms to find the main topic clusters and the gaps between them, and its built-in AI proposes ideas that link those gaps. Users import data, read the graph and generate questions or summaries.
Best for Researchers, writers and SEO practitioners who want to see what a body of text covers and which connections it leaves out.

What is InfraNodus?
InfraNodus is a text analysis and visualisation tool built on network science. It converts any text into a graph in which words are nodes and co-occurrences are links, then identifies influential keywords, topical clusters and structural gaps, meaning groups of ideas that are not yet connected. An AI chatbot inside the app uses that structure to produce overviews, summaries and research questions. Data can be typed into a live editor or imported from PDF, text, Markdown and CSV files, Google and Google Scholar results, YouTube transcripts and comments, whole websites, Amazon reviews and RSS feeds. Topic modelling and sentiment analysis are included. The graphs can also serve other software through an API, an MCP server for clients such as Claude and ChatGPT, an n8n node, an Obsidian plugin, a browser extension and a VSCode or Cursor extension.
