Code Explanation

Paste any code snippet to get a clear breakdown of what each line does, with a summary of the overall structure and detected constructs.

How It Works

This tool performs static analysis of your code entirely in the browser. It tokenizes each line and matches patterns against known language constructs — function declarations, variable assignments, loops, conditionals, class definitions, imports, return statements, and more.

The language is auto-detected by examining file markers, syntax patterns, and keyword frequency. Each line receives a plain-English explanation describing its purpose and role in the code. The summary provides a high-level overview of the structure, including detected constructs and basic statistics.

This is a heuristic-based analyzer, not an AI model — it works offline and never sends your code anywhere. It handles common patterns well but may not interpret highly unconventional or obfuscated code accurately.
