InfraNodus is a text analysis tool based on knowledge graphs and network analysis, driven by network analysis techniques and AI, designed to help users discover hidden patterns and content gaps in texts, rather than merely providing generic summaries.
In terms of use, InfraNodus can analyze notes, ideas, PDFs, CSVs, Google search results, survey questionnaires, tweets, spreadsheets, and other types of text, using text networks to reveal the most important topic clusters and the gaps between clusters, and leveraging built-in AI models or MCP servers to fill these gaps and enrich perspectives. Its positioning is "AI thinks with you, not for you."
Main capabilities include: visualizing any text as a knowledge graph, with words as nodes and co-occurrence relationships forming connections; identifying related idea clusters (topic modeling) through graph theory algorithms, discovering the most influential concepts and hidden intermediary nodes, and revealing structural gaps in discourse; supporting sentiment analysis and segmented topic extraction; providing a built-in text editor for real-time analysis, and also allowing file uploads or running in a local folder; a built-in GPT-5.4 / Claude Opus-powered AI chatbot that can generate text overviews, summaries, research questions, facts, and innovative ideas; supporting online sharing, embedding, or exporting high-resolution images of graphs; data is private, exportable, and hosted in the EU.
The workflow consists of five steps: import / connect via MCP, get an overview, zoom into details, discover gaps, generate ideas.
Import sources are abundant: supports batch processing of multiple text files (txt, pdf, md) with automatic topic extraction; supports CSV and spreadsheets, allowing import by column and using specific column values as filters (e.g., positive/negative); supports copy-pasted text and voice input for real-time analysis; supports Google search, Google Scholar, and related search query analysis; supports analysis of YouTube videos, comments, channels, playlists, and search results; supports analysis of entire websites and single web pages, and sitemaps; supports analysis of Amazon product search results and reviews; supports RSS and news feed imports.
In terms of integration capabilities, InfraNodus can connect to LLM clients such as ChatGPT and Claude through an MCP server (MCP address:https://mcp.infranodus.com），通过官方 The n8n node integrates with n8n and, through configuration files, connects to IDEs such as Cursor, Claude Code, OpenClaw, and Antigravity, providing a VSCode / Cursor extension and an Obsidian Graph View plugin. After connecting to the MCP server, you can install its free skills collection, run the installation command in the terminal and select the target agent; you can also run /plugin marketplace add infranodus/skills and /plugin install infranodus-all@infranodus-skills in the Claude Code prompt. To install a single skill, add --skill infranodus after the npx command.
Use cases cover research and creative ideation, consulting and marketing (discovering untapped trends and market opportunities), SEO (discovering content gaps and optimizing strategies for search engines and LLMs), qualitative analysis (analyzing open-ended questionnaires, interviews, etc.), competitive intelligence (analyzing competitor websites and reports to discover ideas no one has connected), topic analysis and customer feedback visualization, real-time data analysis (news, search results, tweets, Amazon reviews), research paper and note/book analysis, mind mapping and reasoning ontology construction, etc.
Its principle is to visualize text as a knowledge graph, using advanced graph theory algorithms to identify clusters, highlight influential nodes, and reveal gaps, and using AI algorithms to generate insights and new ideas based on clusters and gaps. Users can use the graph as a "steering device" to guide the model's attention, maintaining a direct connection to the source material to avoid LLM hallucinations. The tool's philosophy originates from the "ecology of mind," aiming to promote ecological dynamics and diversity at the cognitive level, and can serve as "mind antivirus software" against paranoid loops and narrow thinking.
Regarding limitations and pricing, the official offering provides a 14-day free trial, after which it becomes a paid plan. Specific prices and quotas (such as upload file size, AI credits, number of imports, etc.) differ by tier. Prices do not include VAT for private customers in the EU. Annual plans can lock in the current price and save costs. For details, refer to the official website.
