The AI writes
the code.
You need to understand it.
Cograph renders your project as a live call graph inside VS Code — updating in real-time as AI agents rewrite your codebase. Making the invisible visible.
AI writes the code.
Can you understand it?
Copilot, Cursor, Claude — AI coding agents are shipping features at unprecedented speed. But every new function, every refactor, every generated file makes the call graph harder to hold in your head.
The mental model you had an hour ago is already out of date. Code review catches bugs, not architecture drift. And onboarding a new engineer into an AI-accelerated codebase? Good luck.
Everything you need to see
how your code actually works
Function Relationships
See every call and dependency across your entire project. Instantly understand what calls what — and trace the full chain from any function.
Git Integration
Highlight what changed between commits. See exactly which nodes and edges were added, removed, or modified — diff your architecture, not just your code.
OOP Class Overlay
Toggle class boundaries over the graph. Methods group visually by their parent class — perfect for object-oriented Python and TypeScript codebases.
Folder Structure
Color-code nodes by directory. Spot cross-module dependencies at a glance and identify coupling between packages before it becomes technical debt.
Graph Intelligence
PremiumAI-powered insights surface hidden complexity, dead code, and dependency cycles. Ask natural language questions about your architecture.
Zero config.
Instant visibility.
Open any Python, TypeScript, or JavaScript project
No configuration files. No setup wizards. Just open your project folder in VS Code like you always do.
Run CoGraph: Visualize Project
Hit ⌘⇧P (or Ctrl+Shift+P) and run the command. Cograph parses your project and builds the call graph in seconds.
Explore the live call graph
Pan, zoom, click nodes to inspect function details. The graph updates automatically as you — or your AI agent — changes the code.
Supported languages
Your codebase,
finally visible.

Ship faster, break less
When you're the entire team, architectural clarity isn't a nice-to-have — it's the difference between a fast iteration loop and debugging for hours. Cograph keeps your mental model current without effort.
- Understand AI-generated code before shipping it
- Spot dead code and orphaned functions
- Onboard faster to unfamiliar repos
Code review that sees the whole picture
PR reviews catch logic bugs. Cograph catches architecture bugs. Share graph snapshots in reviews to communicate intent, not just code.
- Review architectural impact of PRs
- Identify unexpected cross-module dependencies
- Share graph state as team documentation
Architectural oversight, not micromanagement
Get a bird's-eye view of how your codebase is evolving — especially in high-velocity AI-driven sprints — without interrupting engineers or reading every line of code.
- Track architecture health over time
- Spot coupling and complexity spikes early
- Communicate system structure to stakeholders
