How AI Code Explanation Works
The tool sends your code to Anthropic's Claude API, which analyses the syntax, control flow, data structures, and patterns. Claude returns a structured explanation: what the code does, how it works step by step, potential issues, and complexity analysis. This is invaluable for understanding unfamiliar codebases, reviewing pull requests, and learning new languages.
