InfraNodus

InfraNodus is a web-based visual AI text analysis tool for researchers, writers, data scientists, and marketing strategists who need to understand large bodies of text as an interactive knowledge graph.

Key capabilities include:

• Text-to-network visualization that turns word co-occurrences into nodes and edges, enabling non-linear exploration with zoom and filtering
• AI-assisted graph analytics to surface influential keywords, topical clusters (topic modeling), and structural gaps between themes that can guide research questions and ideation
• Flexible imports from plain text, PDFs, Markdown/Obsidian notes, CSV/spreadsheets, Google search results, YouTube transcripts/comments, websites/URLs/sitemaps, RSS/news, and social content such as tweets
• Sharing and interoperability via shareable URLs and embeddable public graphs, plus exports as images and graph files (CSV/GEXF) for tools like Gephi and Pajek

Pricing: Paid with a free 14-day trial; Basic €12/mo, Advanced €32/mo, Premium €66/mo (annual billing options shown).

What makes it notable is its focus on network science and graph theory to reveal relationships and blind spots in discourse, not just summaries. It is developed by Nodus Labs (since 2012) and operated by InfraNodus SAS (Paris, France), with EU hosting and GDPR-oriented positioning, plus API and MCP server options for integrating knowledge graphs into LLM workflows.
