## What it is
Oh-my-mermaid (omm) is a CLI tool plus Claude Code skills that uses AI to analyze a codebase and generate architecture documentation as nested Mermaid diagrams. It includes an interactive viewer and optional cloud hosting for the generated architecture docs.

## Use cases
- generate architecture diagrams from my codebase with AI
- visualize how a large codebase is structured
- create mermaid diagrams of data flow and integrations
- document architecture for humans after AI-generated code
- onboard new developers with navigable architecture docs
- recursively break down complex modules into nested diagrams

## When to choose
- you use Claude Code or similar AI coding tools and want architecture docs generated automatically
- you need visual, nested Mermaid diagrams of a complex codebase
- you want an interactive viewer to explore architecture hierarchically

## When to avoid
- you need deterministic, non-AI-generated documentation
- you don't use an AI coding tool that supports skills
- you need docs generated in CI without an AI agent
