License Generator

Picking a license shouldn't require a law degree. This tool explains each license in plain English and generates the LICENSE file for you.

One command. Zero config. Just works.

Quick Start

npx ai-license

What It Does

• Interactive license selection with explanations
• Generates complete LICENSE files
• Explains what each license actually means
• Covers MIT, Apache, GPL, BSD, and more

Usage Examples

# Interactive mode
npx ai-license

# Quick MIT license
npx ai-license --type mit --name "Jane Doe"

# Explain a license before choosing
npx ai-license --explain apache-2.0

Best Practices

• MIT for simplicity - do whatever you want, just keep the copyright
• Apache for patents - includes patent protection
• GPL for copyleft - derivatives must also be open source
• Check dependencies - some licenses are incompatible

When to Use This

• Starting an open source project
• Not sure which license fits your needs
• Want to understand license implications
• Need to generate LICENSE file quickly
