Module Preview
Every module follows the same structure — chapters with objectives, learning content, knowledge checks, and coding challenges. Here's an interactive sample from our Getting Started with Cograph module:
Chapter 1: The Knowledge Graph Mental Model
- Understand what a knowledge graph is and why it matters for retention
- Identify the three types of knowledge Cograph captures
- Recognize your own expertise surface area in the graph
Why Knowledge Gets Lost
Every organization has the same invisible problem: the knowledge that makes your company work lives inside people's heads, not in your systems.
When someone leaves — whether it's a planned retirement, a surprise resignation, or a role change — a piece of your organizational memory walks out the door. Documentation helps, but documentation captures what people remember to write down, not what they actually know.
Cograph solves this differently. Instead of asking people to document everything upfront (which nobody does), it continuously maps expertise from signals they're already producing: code commits, Slack conversations, document edits, and meeting patterns.
// Each employee node has relationships to topics they know
MATCH (e:Employee {email: "sarah@company.com"})
-[r:HAS_EXPERTISE]->(t:Topic)
RETURN t.name as topic, r.score as score
ORDER BY r.score DESC
LIMIT 5
// Result:
// "API Authentication" → 0.94
// "PostgreSQL Optimization" → 0.87
// "CI/CD Pipelines" → 0.81
// "React Patterns" → 0.76
// "Infrastructure as Code" → 0.71A simplified view of how Cograph models expertise in the graph
Cograph captures: (1) Technical expertise — code ownership, architectural decisions; (2) Process knowledge — how things actually get done day-to-day; (3) Relationship capital — who knows who, who to call for what.
How Expertise Scores Work
Each employee–topic relationship has a score between 0 and 1, built from multiple signals:
- Code ownership (40%) — proportion of commits, files last touched - Document authorship (30%) — Notion pages, Google Docs created or heavily edited - Communication patterns (20%) — Slack threads where the person is the go-to responder - Peer recognition (10%) — mentions, direct reports' engagement
The score is continuously updated as new signals arrive. It's not a one-time assessment.
What is the primary advantage of Cograph's signal-based approach over traditional documentation?
Once your organization connects its integrations, you can view your own knowledge profile from Settings → My Profile. Most people are surprised by what Cograph already knows about them.
Key Takeaways
- The knowledge graph maps expertise continuously from real work signals
- Expertise scores are weighted composites across code, docs, communication, and recognition
- Three knowledge types: technical, process, and relationship capital

Progress Tracking
Cograph tracks progress at the chapter level. Each chapter has a "Mark Complete" button — completion is self-reported and not gated on quiz scores.
Module purchased but no chapters opened
At least one chapter marked complete
All chapters and required quizzes finished
Manager Visibility
Managers can see the learning progress for their direct reports from Team → Learning Progress. Visible data includes:
- Which modules are purchased and assigned
- Chapter completion status (complete / not started)
- Time spent per module
- Quiz scores (not individual answers)
Knowledge Graph Integration
Completed modules feed back into the knowledge graph as lightweight expertise signals. Completing the GraphQL APIs module adds a small positive signal to your GraphQL expertise score — weighted far lower than direct work experience but useful for employees building new skills.
This means learning modules are useful for closing gaps, but won't create false expertise signals that distort successor matching — real work experience always dominates.
