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.
