The AI Code Explainer is a free, browser-based tool that explains code in plain English using AI on your computer. Paste any code snippet and get a clear breakdown of what it does and how it works. Because the AI runs entirely on your device, your proprietary code stays on your computer.

How to Use

Paste your code

Paste a code snippet in any programming language into the input field.

Choose detail level

Select Brief for a high-level overview or Detailed for a step-by-step breakdown.

Generate explanation

Click "Explain Code" to get a plain-English explanation.

Learn and share

Use the explanation to understand unfamiliar code or share it with teammates.

Tips

For best results, paste a complete function or logical block rather than a single line.
Use "Brief" when you just need to know what the code does, and "Detailed" when you want to understand how it works.
Try pasting regex patterns — the AI breaks them down piece by piece.
Great for code reviews — paste a colleague's code to quickly understand their approach.

Frequently Asked Questions

Is this AI code explainer private? Does it send my code to a server?

No. The AI runs on your computer, so your proprietary code stays on your computer and nothing is sent to OpenAI, Anthropic, or anyone else — ideal for work codebases.

What programming languages are supported?

The AI can explain code in any language — JavaScript, Python, Java, C++, Go, Rust, SQL, and more. It recognizes syntax patterns automatically.

Can it explain regex patterns?

Yes. Paste a regex pattern and the AI will break it down step by step, explaining what each part matches.
