Story arc

How this shipped

Exploring the boundaries of artificial intelligenceThree beats: what pressed against the work, how the stack answered, and what changed once it was live.

I · Constraint

The brief

New developers spend weeks understanding large codebases. Architecture knowledge lives in senior developers' heads, not documentation.

II · Build

The craft

Auto-generates interactive architecture diagrams from code analysis. RAG-powered Q&A answers questions by searching through indexed codebase context.

III · Proof

What moved after launch

Reduces onboarding time from weeks to days. Architecture diagrams update automatically as code changes. Q&A answers 80% of common codebase questions.
