Preview

Ever open a file and have absolutely no idea what it does? Maybe you inherited a codebase, maybe it's your own code from six months ago. Either way, this tool reads any code file and explains it in plain English. You pick the level, from beginner friendly to expert deep-dive, and it breaks down what every part does.

Code Explainer

One command. Zero config. Just works.

Quick Start

npx ai-explain src/utils.ts

What It Does

Reads any code file and produces a clear, human-readable explanation
Supports three explanation levels: beginner, intermediate, and expert
Works with any programming language the AI model understands
Breaks down functions, classes, and logic flow step by step
Prints the explanation right to your terminal

Usage Examples

# Explain a file at beginner level (default)
npx ai-explain src/auth.ts

# Get an expert-level breakdown
npx ai-explain src/parser.ts --level expert

# Understand a Python script
npx ai-explain scripts/deploy.py --level intermediate

Best Practices

Start with beginner - Even if you're experienced, the beginner explanation often catches things you'd skim over. Work up from there.
Use it during code review - When reviewing someone else's PR, run this on files you don't recognize. Saves time and catches misunderstandings.
Pair it with documentation - Use the explanation as a starting point for inline comments or docs. It's faster than writing from scratch.
Try it on legacy code - Old codebases with no docs are where this tool really shines. Point it at the scariest file first.

When to Use This

You just joined a team and need to understand the codebase fast
You're reviewing a PR and one file makes no sense
Legacy code with zero comments or documentation
Learning a new language and want to understand example code

How It Works

The tool reads your source file and sends the content to an AI model along with your chosen explanation level. The model analyzes the code structure, identifies patterns, and produces a plain English walkthrough of what the code does and why.

Requirements

No install needed. Just run with npx. Node.js 18+ recommended.
