AI text analysis with knowledge graphs to reveal topics and content gaps
Convert any text into a visual network of words and their connections, so topics and their relationships become explicit at a glance.
Automatically surface the structural gaps between topical clusters — the under-connected areas where original ideas are most likely to appear.
Generate per-topic summaries and AI-created questions that bridge two clusters, turning a graph into a concrete line of inquiry.
Connect InfraNodus to Claude, ChatGPT, Cursor, or your own agent over MCP so graph reasoning grounds the model's answers and actions.

AI research platform for reading, understanding and writing scientific papers
Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
