Code Comment Generator
Add meaningful inline comments to complex code that explain the WHY, not the WHAT. Uses AI to analyze code logic and generate contextual explanations for business rules, edge cases, and algorithmic decisions.
🚀 Add meaningful inline comments to your code automatically. This tool reads complex code and explains the WHY behind it—not just what it does. One command, zero setup needed. Perfect for algorithms, business logic, and tricky edge cases that future developers need to understand.
💡 Use this when onboarding new team members, inheriting undocumented codebases, or documenting complex logic before you leave. Choose from three comment styles: concise, detailed, or beginner-friendly. Preview changes with --dry-run before applying them to your files.
✨ Powered by AI, it understands context and intent—no generic comments here. Just run npx ai-comment ./src/file.js and get thoughtful explanations that actually help your team.
