## InfraNodus

InfraNodus approaches text analysis through network science rather than plain summarization. Paste in notes, papers, interviews, search results, or an entire Obsidian vault, and it builds a knowledge graph where words become nodes and co-occurrence becomes connections. The graph highlights the main topical clusters and, crucially, the structural gaps — areas that are barely connected to the rest — which are where genuinely new ideas tend to emerge. The methodology behind it has been peer-reviewed and presented at The Web Conference (ACM) 2019.

Beyond visualization, InfraNodus layers AI on top of the graph. You can generate summaries per topic, ask for research questions that bridge two clusters, and develop missing concepts with AI. It is widely used across AI-assisted thinking, qualitative and thematic analysis, survey and sentiment work, market research, and search engine and LLM optimization. For SEO specifically, it can map what Google ranks against what ChatGPT and Claude actually answer, then compare both to real search demand to reveal topics nobody covers yet.

A distinctive modern angle is its role as a reasoning substrate for AI agents. Through an MCP server, InfraNodus exposes graph tools to Claude, ChatGPT, Cursor, or any MCP client, so an agent can generate a knowledge graph of a codebase or note collection and detect what is missing before acting. The platform also ships ready-made graph examples, ontologies, plugins and extensions for Obsidian, VS Code, Cursor, and browsers, a CLI skill, and integration pathways via API and no-code tools, making it as much an infrastructure layer for knowledge work as it is an analysis app.

**Pricing & Plans:** Freemium with a free plan that requires no credit card, plus a free trial and paid subscription tiers; API and consulting or training services are also available. See the site for current plan details.

- **Knowledge Graph Visualization:** Convert any text into a visual network of words and their connections, so topics and their relationships become explicit at a glance.
- **Content Gap Analysis:** Automatically surface the structural gaps between topical clusters — the under-connected areas where original ideas are most likely to appear.
- **AI Summaries and Research Questions:** Generate per-topic summaries and AI-created questions that bridge two clusters, turning a graph into a concrete line of inquiry.
- **MCP Server for AI Agents:** Connect InfraNodus to Claude, ChatGPT, Cursor, or your own agent over MCP so graph reasoning grounds the model's answers and actions.
- **SEO and LLM Optimization:** Compare what search engines rank with what AI assistants answer and with real demand to identify uncovered topics to write about.

**Strengths:** Combines rigorous network science with modern LLM capabilities rather than relying on plain summaries; Content gap analysis produces genuinely actionable research and writing directions; Deep integration with AI agents via MCP and with tools like Obsidian, VS Code, and Cursor; Backed by a peer-reviewed methodology presented at an ACM conference

**Limitations:** The graph-based interface has a learning curve compared with a simple chat box; Getting full value requires feeding it substantial text, not just a sentence or two; The sheer number of features, ontologies, and integrations can feel overwhelming at first

## Liminary

Liminary targets a familiar professional failure mode: you do the research, then spend the first hour of the next project re-finding it. The tool acts as a persistent memory layer. Articles, reports, PDFs, videos and AI chats are saved with one click while you browse, and you can add your own notes and context as you read, so the stored knowledge reflects your thinking and not just the source text.

Retrieval is the differentiating part. Rather than waiting for you to search, Liminary proactively surfaces what is relevant while you write, and it now includes Magnet, a meeting sidekick that pulls in the right material in real time. Answers are grounded in your saved sources, with every insight traceable to a citation and every source one click away. Fact-checking and gap detection run against your own material rather than the open internet, so you can verify claims and spot missing pieces before someone else does.

Security is positioned as a core feature rather than an afterthought: data is encrypted, siloed to your workspace, and never used to train AI models, with the team crediting ex-Dropbox security, ML and search engineers. The product is aimed at consultants, researchers, analysts and small teams whose recommendations carry professional risk if the underlying facts are wrong.

Practicalities: Liminary ships as browser extensions for Chrome and Firefox with a rated 5-out-of-5 presence on the Chrome Web Store, and the vendor publishes benchmark posts on long-term memory evaluation. Pricing structure beyond a free download is presented on the site; check there for current plan tiers.

**Pricing & Plans:** Free download available to get started. Subscription tiers for professional and small-team use are listed on the Liminary site. Check the official pricing page for current plan details, since published tiers may change.

- **One-click saving anywhere:** Capture web pages, PDFs, videos, reports and LLM chats while you browse, then annotate them with your own notes and context.
- **Proactive recall:** Instead of waiting for a search, Liminary surfaces the relevant saved material while you write and inside meetings.
- **Magnet meeting sidekick:** A meeting companion that pulls in the right information at the right moment, then saves the summary, full transcript and your notes for later recall.
- **Sourced, traceable answers:** Every answer points back to where it came from, internal or external, so you can verify claims rather than trust a black box.
- **Fact check and gap detection:** Validate claims against your own saved sources and find what is missing in a draft, including directly inside Notion.

**Strengths:** Proactive recall means relevant knowledge finds you instead of requiring a search; Answers stay traceable to saved sources, which suits high-stakes professional work; Captures many source types in one place: pages, PDFs, videos and AI chats; Explicit privacy stance: encrypted, siloed per workspace and never used for model training

**Limitations:** Value depends on you actually saving sources, so the habit has to be built first; Overlaps with note tools like Notion, which can mean deciding where knowledge should live; Full plan structure is not fully clear from the landing page alone, so pricing needs checking
