Building an AI Code Lab Assistant for a Friend: My Hacktoberfest Weekend Project

Description and use

An interactive code‑debugging assistant that provides real‑time error analysis and step‑by‑step fixes, helping users learn and resolve issues independently.

Problem

A friend studying computer science struggled with debugging errors and understanding complex code blocks late at night when study groups were unavailable.

Outcome

The assistant enables the friend to debug code and understand errors in real time, improving learning efficiency and reducing reliance on external help.

Workflow

• 1. User pastes or writes code in the Monaco Editor interface.
• 2. The frontend sends the code to the backend via Express API.
• 3. The backend forwards the prompt to an LLM API for analysis.
• 4. The LLM returns error detection, explanation, and fix suggestions.
• 5. The frontend displays the feedback and suggested code changes to the user.

Evidence
