AI Code Explainer
Paste any code snippet and get a clear, plain-English explanation of what it does.
The AI Code Explainer reads a snippet and explains it in plain English — the overall purpose first, then a walkthrough of the key parts. It’s perfect for unfamiliar code, code review, onboarding, or learning a new language.
When it helps
- Reading legacy or third-party code you didn’t write.
- Learning — see how a pattern or algorithm actually works.
- Review — get a second read that surfaces edge cases and improvements.
How it works
Your code is sent securely through our server to the AI model and the explanation is returned — your API key is never exposed in the browser. Paste a focused function or block for the clearest results, and always verify against your own understanding.
