Infranodus

InfraNodus is a text analysis tool that represents any text as a knowledge graph in order to reveal its main topics, influential concepts and the structural gaps between them. Words and entities become nodes, their co occurrences become connections, and network science algorithms highlight topical clusters, top keywords and trends. A built in AI then uses that structure to generate summaries, research questions and ideas that bridge the gaps. The method is described in a peer reviewed paper presented at The Web Conference in 2019. It serves researchers, consultants, writers, marketers and SEO specialists doing ideation, qualitative analysis and content gap research. Text can be written in the built in editor, uploaded as files such as PDFs and CSVs, or imported from Google search results, YouTube, X, Amazon reviews, websites, RSS feeds, Evernote, Obsidian and scientific databases. An MCP server and an API let users connect graphs to their own LLM tools and augment RAG prompts, and there are browser extensions and an Obsidian plugin. Data is private by default, exportable and hosted in the EU. All plans carry a 14 day free trial. On annual billing the site lists Basic at 12 euros per month for personal and academic use, Advanced at 32 euros per month with API and MCP access and commercial use, and Premium at 66 euros per month with higher quotas, training and faster support. The page says annual plans save up to 35 percent against monthly billing, prices exclude VAT for EU private customers, and student and educational discounts are available on request. InfraNodus is developed by Nodus Labs, which states it takes no investor funding or external grants.
