Understand your code, fix your bugs, learn as you go

• Explain — what the code does, in plain language
• Debug — find and fix errors, with the reason
• Optimise — a cleaner or faster version, with the trade-off
• Generate a small project from a description
• Works across JavaScript, TypeScript, Python, Java, C++, SQL and more

1. 1

   Paste your code

   Choose the language and what you want done.

2. 2

   Read the explanation

   See what changed or what the code does, step by step.

3. 3

   Rewrite it yourself

   Try the fix in your own words before copying — that's how it sticks.

• “Why does my loop run one time too many? [paste code]”
• “Explain this recursive function and its time complexity.”
• “Scaffold a simple to-do list app in Python with a menu.”

• A coding request uses 3 credits.
• Generated code can contain bugs or outdated APIs. Run it, test it, and read it before you rely on it.
• If your course forbids AI-written code, use it to understand and debug rather than to produce your submission.
