Code Explainer
Paste a snippet to get a plain-English, line-by-line breakdown of what the code does — functions, loops, conditionals, returns and more. Works with JavaScript, Python and similar C-style languages. Everything runs locally in your browser — nothing is uploaded.
This explainer recognises common code patterns — it's a reading aid, not AI, so it can't reason about your program's overall logic. Use it to learn the building blocks, then verify the details yourself.
About this code explainer
Each line is matched against common patterns — declarations, functions, loops, conditionals, returns and calls — and described in plain English.
Tuned for JavaScript and Python but handles most C-style syntax (Java, C, Go, Rust) too.
Perfect for beginners reading unfamiliar code or reviewing a snippet quickly.
It reads syntax, not intent — it won't explain why the code exists or catch bugs.
Export the code with inline explanations as commented text for your own reference.
Your code is analysed entirely in your browser — nothing is uploaded.
