Explanation

What You Can Do

Generate Code

Describe what you need in plain English and get production-ready code in Python, JavaScript, TypeScript, Java, C++, Go, Rust, Ruby, PHP, SQL, HTML, CSS, or Shell.

Debug & Fix

Paste buggy code and get the fix. The AI identifies errors, explains what went wrong, and returns corrected, working code.

Explain Code

Paste any code and get a clear, line-by-line explanation. Great for learning new languages or understanding unfamiliar codebases.

Convert Languages

Translate code between 13 programming languages. Python to JavaScript, Ruby to Go, or any other combination — with idiomatic output.

Code Review

Get feedback on bugs, security issues, performance, readability, and best practices. Like having a senior developer review your code.

Code in Chat & Coder

You can also generate code in Chat conversationally, or use Coder IDE for a full browser-based coding environment.

How to Use

Pick language and mode

Select your programming language and what you want to do: generate new code, debug existing code, explain it, convert between languages, or get a code review.

Describe or paste code

For generation, describe what you want in plain English. For debug/explain/convert/review, paste your code. Be specific about requirements and edge cases.

Generate and review

Click the button (or press Ctrl+Enter) and the AI produces your code with syntax highlighting. Explanations appear separately below for debug and review modes.

Copy and use

Copy the generated code with one click. The output is production-ready with comments and proper formatting. Iterate by adjusting your prompt and generating again.
