AI Code Explainer — understand any code online

You open a file someone else wrote — or that you wrote months ago — and you have no idea what it actually does. Reading it line by line takes ages, and you're still not sure. We made something for exactly that — AI Code Explainer — right in your browser.

What it does

Paste any piece of code and it gives you a plain-English summary of what the code is for, a step-by-step walkthrough of how it works, and a list of the gotchas — the tricky bits and things that could trip you up. No need to know the language inside out; it explains it in words anyone can follow.

Why it helps

It saves you the slow, frustrating part of reading unfamiliar code. Reach for it when you've inherited a project, when you're learning and stuck on an example, when you're reviewing a snippet before you trust it, or when you just need to remember what your own old code was doing.

How to use it

  1. Open AI Code Explainer.
  2. Paste the code you want explained.
  3. Read the summary, the step-by-step walkthrough and the gotchas.
