Artificial intelligence (AI) is rapidly changing how we work, and the field of software development is no exception. Code writing is one of the areas that is seeing the most productivity boosts from using AI. AI code assistants are a new breed of AI-powered tools helping developers write code faster and more safely. This article covers the best AI code assistant tools and will help you choose the right one for your needs.

What is an AI Code Assistant?

An AI code assistant is a software tool that uses artificial intelligence to help developers write code faster and more accurately. It does this either by generating code based on prompts or suggesting code for auto-completion as you write code in real time.  Here are just a few things AI code assistants can do:

  • Integrate with popular code editors you use, like Visual Studio Code
  • Generate complete code snippets from prompts or code comments
  • Auto-complete lines of code you are writing in real-time
  • Detect errors, bugs, and security vulnerabilities with your code
  • Help comment code so it is easy to refer back to

Why Use an AI Code Assistant?

Have you considered supercharging your coding experience with AI coding assistants? These powerful tools revolutionize productivity, enabling faster and more accurate code writing while freeing up time for creativity for the challenging solutions you are working on.

For example, using Amazon CodeWhisper in Visual Studio Code, you can simply write a comment describing the code you want to generate, and it will suggest the entire code snippet for you to use and edit as needed.

And once you start writing or editing the code, the code assistant will continuously suggest code to help you fill in the gaps.

But that’s just the start. They can act as vigilant guardians, catching errors early and saving you debugging headaches. Additionally, AI code assistants elevate code quality, offering expert guidance to write efficient, maintainable, and secure code. And they are one of the best learning tools for exploring languages you are not familiar with.

Using them creates efficiencies at every stage of development, no matter what type of project you are working on. Many of the best development teams have already switched to many of the solutions below.
