The Connection You Didn't Know You Had
You're chatting with Emma about a product challenge she's facing. Midway through the conversation, she mentions she needs to hire a UX designer with experience in fintech.
You pause. You know someone who fits that description. But who? You've got 800+ LinkedIn connections. Was it Jordan? No, Jordan's a developer. Sarah? No, she's in marketing. The name is on the tip of your tongue, but you can't quite grasp it.
Three days later, you're scrolling through your feed and see Alex post about finishing a fintech UX project. That's when it hits you: Alex is exactly who Emma needs. And you forgot.
Here's the painful truth: Your network is more valuable than you realize, but only if you can actually access the right connections at the right time.
The problem isn't that you don't have valuable connections. It's that your connections exist as isolated data points instead of an interconnected system. You're sitting on a LinkedIn knowledge graph, but you can't query it. And that means opportunities slip through the cracks every single day.
What Is a Knowledge Graph (And Why You Need One)?
A knowledge graph is a network of interconnected information—entities (people, topics, companies) linked by relationships and context.
Think of it like this:
- Traditional contact list: Sarah, Marketing Director at XYZ Corp.
- Knowledge graph: Sarah → works in → SaaS marketing → specializes in → content strategy → connected through → James (mutual connection) → interested in → storytelling, positioning → last discussed → brand differentiation in Feb 2025.
The difference? A contact list is a flat database. A knowledge graph is a network. And networks reveal patterns, overlaps, and opportunities that flat lists can't.
Why Your Brain Can't Do This Alone
Human memory is associative—you remember things by connection, not by search. That's great when you have 20 close friends. But when you have 500+ LinkedIn connections, each with their own expertise, interests, projects, and networks, your brain can't hold the full graph.
You know someone who knows something about something—but you can't surface it quickly enough to be useful. That's the LinkedIn knowledge graph problem. And it's costing you referrals, introductions, and opportunities.
This is where tools like the ANDI Chrome Extension become essential—because ANDI builds and maintains your personal knowledge graph automatically, so you can query it like a search engine.

The Building Blocks of a Personal Knowledge Graph
Every knowledge graph has three core components: nodes, edges, and attributes. Let's break them down in the context of LinkedIn relationships.
1. Nodes (The Entities)
Nodes are the "things" in your graph—people, companies, topics, projects.
Examples:
- People: Sarah, Jordan, Alex
- Topics: Product management, fintech UX, remote team leadership
- Companies: XYZ Corp, early-stage SaaS startups
- Projects: Q2 product launch, healthcare expansion
2. Edges (The Relationships)
Edges connect nodes—they define how things relate to each other.
Examples:
- Sarah → works in → SaaS marketing
- Jordan → interested in → AI implementation
- Alex → specializes in → fintech UX
- Emma → needs → UX designer with fintech experience
3. Attributes (The Context)
Attributes are the details that make nodes and edges meaningful—context, history, notes.
Examples:
- Sarah: Last interaction = 2 weeks ago; Reciprocity = 85%; Tag = Tier A
- Jordan: Mentioned transitioning to product management in March 2025
- Alex: Just completed a fintech UX project; Open to freelance work
When you combine nodes, edges, and attributes, you get a queryable system: "Show me everyone in my network who specializes in UX and has fintech experience." Boom—Alex.
How ANDI Builds Your LinkedIn Knowledge Graph
Building a knowledge graph manually is theoretically possible—but practically impossible. You'd need to tag every person, log every topic, and update every connection as contexts change. No one has time for that.
That's why ANDI automates the process. Here's how:
1. Automatic Tagging and Categorization
As you interact with people on LinkedIn—comments, DMs, profile visits—ANDI automatically tags them based on:
- Their stated expertise (job title, skills)
- Topics they post about
- What you've discussed with them
- How you've categorized them (Tier A/B/C, potential client, collaborator, etc.)
You don't manually tag everyone. ANDI infers tags from behavior and content, then surfaces them when you need them.
2. Topic Extraction from Conversations
ANDI reads your DM conversations and extracts key topics: "Sarah discussed content strategy and storytelling." Now when you search "storytelling," Sarah appears—even if "storytelling" isn't in her job title.
This turns implicit knowledge (you know Sarah cares about storytelling because you talked about it) into explicit data (ANDI remembers that Sarah cares about storytelling).
3. Relationship Mapping
ANDI helps you track not just who you know, but how you know them:
- Introduced by James
- Met at XYZ conference
- Connected through mutual interest in AI
This relational context is critical. When you need to make an intro, knowing how two people are connected makes the introduction more natural.
4. Project and Goal Tracking
People aren't static—they have projects, goals, and timelines. ANDI captures these as nodes in your graph:
- Emma → currently working on → Q2 product launch
- Jordan → exploring → transition to product management
- Alex → seeking → freelance UX projects
Now when Emma says "I need a UX designer," ANDI surfaces Alex—not because you manually connected those dots, but because the graph reveals the connection.

Querying Your Knowledge Graph: From Static to Dynamic
The value of a knowledge graph isn't in building it—it's in querying it. Here's where ANDI's LinkedIn knowledge graph becomes a superpower.
Example Queries You Can Run
| Query | What ANDI Returns | Use Case |
|---|---|---|
| "Who in my network works in fintech?" | List of contacts tagged with fintech experience | Exploring a new niche |
| "Who have I not talked to in 6+ weeks?" | Contacts with cooling relationships | Re-engagement outreach |
| "Show me everyone I met through James" | Connections introduced by James | Understanding network clusters |
| "Who's interested in AI and storytelling?" | Contacts at the intersection of both topics | Finding collaboration partners |
| "Who's launching a product in Q2?" | Contacts with Q2 project timelines | Timely check-ins and support |
Without a knowledge graph, these queries require scrolling through hundreds of profiles, re-reading old messages, and hoping you remember. With a graph, they're instant.
Uncovering Hidden Opportunities with Graph Thinking
The magic of a LinkedIn knowledge graph isn't just recall—it's revelation. The graph reveals patterns you couldn't see manually.
Example 1: Cluster Analysis
You run a query: "Who in my network works in early-stage SaaS?" ANDI returns 12 people. You didn't realize you had that many. That's a validated niche—a potential content focus, a service offering, or a community to build.
Example 2: Gap Identification
You notice that none of your Tier A connections work in healthcare, but you've been curious about that space. That's a gap. Time to intentionally build relationships in healthcare.
Example 3: Introduction Opportunities
ANDI shows you that Emma needs a UX designer and Alex is seeking freelance work. You make the intro. Both benefit. And you become known as a connector—which compounds your network value exponentially.

Maintaining Your Graph Over Time
Knowledge graphs aren't set-and-forget. People change roles. Interests evolve. Projects end. A static graph becomes outdated fast.
The good news? ANDI maintains your LinkedIn knowledge graph automatically:
- Profile updates: When someone changes jobs, ANDI updates their node.
- Conversation updates: When you discuss new topics, ANDI extracts and tags them.
- Engagement tracking: When interaction frequency changes, ANDI adjusts relationship strength indicators.
You're not manually updating a database. You're just using LinkedIn normally, and the graph evolves in real time.
From Contacts to Community
A contact list is transactional: "Who do I know?" A LinkedIn knowledge graph is relational: "Who knows what, who's connected to whom, and where are the opportunities?"
When you shift from a contact list to a knowledge graph, you stop seeing your network as isolated individuals and start seeing it as an ecosystem. And ecosystems have emergent properties—opportunities that only exist because of the connections between nodes.
That's when networking stops feeling like work and starts feeling like orchestration. You're not just collecting connections. You're building a community—and leveraging the relationships between people, not just the people themselves.
Frequently Asked Questions
Do I need to manually tag everyone in my network?
Nope. ANDI infers tags from job titles, conversations, and content engagement. You can add manual tags for specificity (like "potential client" or "met at XYZ event"), but the core graph builds automatically as you use LinkedIn.
What if someone's interests or expertise changes?
ANDI updates nodes in real time as people's profiles change or as you have new conversations. The graph evolves with your network, so it stays current without manual updates.
Can I search for people based on specific criteria?
Yes. ANDI's search functionality lets you query by tags, topics, interaction history, or relationship context. Think of it like a Google search for your network.
How is a knowledge graph different from just using LinkedIn's search?
LinkedIn search is limited to profile data (job title, company, location). A knowledge graph includes context you've captured—conversation topics, project timelines, how you met, relationship strength. It's far richer and more actionable.
