How to Use the Code Explainer
- Paste your code into the Your Code panel. Hit Try Sample first if you want to see how it works.
- Pick the language from the dropdown, or leave it on Auto-detect if you are not sure.
- Click Explain Code. Your plain-English explanation appears in the output panel in seconds.
- Copy it into your notes, code comments, or documentation.
What It Does
Paste code, get a plain-English explanation. The tool sends your snippet to an AI model that walks through what each part does: the overall purpose, how the logic flows, and what the tricky bits are. It is built for reading code, not writing it.
It supports 17 languages: JavaScript, TypeScript, Python, Java, C++, C#, Go, Rust, PHP, Ruby, Swift, Kotlin, SQL, Bash, HTML, and CSS. If you are not sure which language you have, leave the selector on Auto-detect.
On privacy: this is an AI tool, so your code is sent to the AI service over an encrypted connection to generate the explanation. CyberScryb does not store your code after the request finishes. Do not paste passwords, API keys, tokens, or other secrets.
When to Use It
Debugging unfamiliar code. Inherit a function you did not write? The explainer walks you through the logic so you can find the bug instead of tracing every line by hand.
Code review. Get a quick read on what a teammate's pull request does before you approve it, including logic you would otherwise have to reconstruct yourself.
Learning a new language. Know Python but not Rust? Paste the Rust code and get an explanation that maps the concepts to what you already understand.
Documenting legacy code. Generate the first draft of inline comments or README explanations from the code itself, then edit it into your own voice.
Frequently Asked Questions
Is this code explainer free?
Yes. The code explainer is free to use with no signup. Paste code and click Explain Code as often as you need.
Does my code leave my browser?
Yes. To generate the explanation, your pasted code is sent to the AI service over an encrypted connection. CyberScryb does not store your code after the request completes. Never paste passwords, API keys, or other secrets into any online tool.
Which languages does it support?
JavaScript, TypeScript, Python, Java, C++, C#, Go, Rust, PHP, Ruby, Swift, Kotlin, SQL, Bash, HTML, and CSS. Leave the dropdown on Auto-detect if you are unsure which language your snippet is in.
How accurate are the explanations?
Usually clear and correct for straightforward code. AI can still misread tricky logic, subtle bugs, or unusual patterns, so treat the explanation as a starting point and verify against your tests and documentation before acting on it in production.
Can it explain minified code?
It can try. Minified code has the meaningful variable and function names stripped out, so the explanation will describe the mechanics but may not recover the original intent. You get better results by beautifying the code first.
Does it write code too?
No. This tool only explains existing code. It does not write new code, refactor yours, or fix bugs. For writing help, try our email writer or humanizer.
