You shipped 3,000 lines you didn't write. Can you explain what they do?
When something breaks at 2am, “the AI wrote it” isn't an answer. If you can't explain your own codebase, you can't debug it, extend it, or trust it.
Code is split into logical sections, each explained in plain English. No more guessing what a function does.
Each section is rated 🟢 Safe, 🟡 Watch, or 🔴 Danger so you know exactly where risks live.
"What breaks if this fails?" — every section tells you the blast radius of a failure.
Identifies external dependencies, API calls, and database queries hidden in AI-generated code.
Results in seconds, not hours. Paste code and get an interactive explanation immediately.
JavaScript, TypeScript, Python, Go, Rust, Java, C#, Ruby, PHP, and every other major language.
Drop any code snippet, function, or entire file into Explain.
Our AI breaks it into sections, rates safety, and identifies risks in seconds.
Read the color-coded breakdown, check the safety ratings, and ship with confidence.
Explain supports all major languages including JavaScript, TypeScript, Python, Go, Rust, Java, C#, Ruby, PHP, and more.
No. Code is analyzed and discarded immediately. We do not store your source code after the explanation is generated.
Credit cost depends on the size of the code. Small snippets cost fewer credits, larger files cost more. You get 500 free credits to start.
Absolutely. Explain is designed specifically to help you understand code written by AI tools like Cursor, GitHub Copilot, Lovable, Bolt, and others.
