Frequently Asked Questions

Which languages are supported?

All major languages — JavaScript, TypeScript, Python, Java, C++, C#, Go, Rust, PHP, Ruby, Swift, Kotlin, SQL, Bash, HTML, CSS, and more. Auto-detect picks the right one automatically.

Who is this for?

Beginners trying to understand a snippet, code reviewers, and senior devs onboarding to unfamiliar codebases.

Does it rewrite the code?

No — it explains what the code does, step by step, in plain English. For rewriting, try our humanizer or ask for a refactor via Pro.

Is my code kept private?

Yes. We don't store code or train on it.

Why Code Explanation Tools Matter

Reading code is harder than writing it. Most developers spend 60 to 70 percent of their time reading existing code � debugging, onboarding to a new codebase, reviewing pull requests, or trying to understand legacy systems that nobody documented. An AI code explainer transforms that process from hours of detective work into seconds of clear, structured explanation.

Our tool uses Google's Gemini model to break down code in any language � Python, JavaScript, TypeScript, Go, Rust, SQL, Bash, and more. It identifies what each block does, explains control flow and data transformations, and highlights potential issues like unhandled edge cases or performance bottlenecks. The output is plain English, not more code.

This is especially valuable for developers learning a new language, students working through assignments, or engineers inheriting a codebase from a previous team. Instead of spending twenty minutes tracing a recursive function through four files, paste the code and get a clear explanation in seconds.

Common Use Cases

Code Reviews: Quickly understand what a teammate's pull request does before approving it. The explainer summarizes logic, identifies patterns, and flags complexity.

Learning New Languages: If you know Python but not Rust, paste the Rust code and get an explanation that maps concepts to what you already understand.

Documentation: Generate the first draft of inline comments or README explanations from the code itself. Edit it into your own voice, but let the AI handle the tedious part of describing what each function does.
