    Review notes

    Context from the listing review and editorial research.

    InfraNodus is a niche powerhouse for discourse analysis — genuinely reveals insights invisible to word clouds or standard NLP. Steeper learning curve than consumer AI tools. Academic and SEO communities praise gap detection; newcomers find graph interpretation challenging. Obsidian integration and MCP server add modern workflow value. Premium pricing justified for professional research use.
