What Is an AI Coding Assistant?

An AI coding assistant is software powered by large language models that helps developers write, understand, review, debug, and improve code.

Instead of searching Stack Overflow for every small issue, developers can simply ask an AI assistant questions like:

• How do I fix this error?
• Can you optimize this function?
• Generate a REST API in Node.js.
• Explain this Python code.
• Convert Java code into C#.

Today’s AI developer tools work directly inside popular editors like Visual Studio Code, Visual Studio, JetBrains IDEs, and even web browsers.
