About this tool
The Code Explainer translates technical code into plain English so you can quickly understand what any function, script, or snippet does — without needing deep programming expertise. It is a practical tool for developers reading unfamiliar codebases, for team leads doing code reviews, and for anyone learning to code who wants to understand examples step by step.\n\nPaste your code, and the tool will explain the logic in straightforward language: what inputs it expects, what processing it performs, and what output or effect it produces. It works across all major programming languages and is particularly valuable when dealing with legacy code, third-party libraries, or code written by other developers.
Examples
Example 1: Explain a Node.js middleware function that handles authentication tokens.\nExample 2: Describe what a CSS animation keyframe block is doing visually.\nExample 3: Walk through a Python list comprehension that filters and transforms data.
