The Big Three of Code AI: Duet AI, GitHub Copilot, and AWS CodeWhisperer

The rise of artificial intelligence (AI) has transformed many industries, and the field of software development is no exception. AI-powered code assistants like Duet AI from Google, GitHub Copilot from Microsoft, and CodeWhisperer from Amazon Web Services (AWS) are changing the way developers work by providing intelligent suggestions, automating repetitive tasks, and helping them write better code faster.

While these three offerings share a common goal, they approach code assistance in slightly different ways, catering to specific needs and workflows. Let's delve into their individual strengths and weaknesses to help you choose the best AI companion for your coding journey.


Duet AI

Let's start with the new kid on the block, who doesn't seem to get mentioned a lot.


Google's entry into the code assistance arena aims to be a versatile companion for developers across various disciplines. It leverages the power of Google's foundation models, including Codey, to offer code recommendations, generate code snippets, and even translate between different programming languages. Duet AI also boasts strong integration with Google Cloud services, making it a natural choice for developers working within that ecosystem.


  • Versatile across various programming languages and disciplines.
  • Integration with Google Cloud services.
  • Strong focus on code generation and translation.


  • Relatively new compared to its competitors, with a smaller user base and potential for limited code completion options.
  • Still under development, with potential for occasional inconsistencies.


GitHub Copilot 

In my opinion, this is the OG of Gen AI coding assistants, and you are most likely to see this being rolled out in your workplace as a company endorsed tool.

Microsoft's solution, born from its partnership with GitHub, is specifically designed for developers, integrating seamlessly into popular code editors and offering context-aware code suggestions and completions. Copilot's advantage lies in its access to the vast repository of code on GitHub, allowing it to learn from millions of real-world examples and provide relevant suggestions.


  • Deep integration with GitHub and popular code editors.
  • Extensive knowledge base thanks to access to GitHub code.
  • Excellent code completion capabilities.


  • Limited functionality outside of code completion and suggestion.
  • Less versatile than Duet AI in terms of supported languages and disciplines.
  • Potential for bias and security concerns arising from training data.


AWS CodeWhisperer

Amazon's offering focuses on the specific needs of developers working on AWS infrastructure. It incorporates knowledge of AWS services and APIs, allowing it to generate code snippets that are tailored to the AWS environment. CodeWhisperer also integrates with popular IDEs and cloud-based tools, making it a convenient option for AWS developers.


  • Deep knowledge of AWS services and APIs.
  • Integration with popular IDEs and cloud-based tools.
  • Tailored code suggestions for AWS-specific tasks.


  • Limited functionality outside of the AWS environment.
  • Less versatile than the other options in terms of supported languages and disciplines.
  • Less mature than Copilot or Duet AI, with potential for limited code completion options.


Choosing the Right Code AI

The best AI assistant for you ultimately depends on your individual needs and preferences. Consider the following factors when making your decision:

  • Programming languages: Ensure the chosen AI supports the languages you primarily use.
  • Development environment: Consider existing workflow integrations with your IDE or cloud platform.
  • Specific needs: Evaluate if you require features like code generation, translation, or specific knowledge of a platform like AWS.
  • Maturity and user base: Opt for a more established solution like Copilot for wider compatibility and a larger pool of learning data.

Ultimately, the best way to find the perfect AI companion is to try them all and see which one resonates best with your coding style and preferences. The future of code assistance is undoubtedly bright, and these three offerings are just the tip of the iceberg. As AI technology continues to evolve, we can expect even more powerful and versatile tools to emerge, revolutionizing the way we write code and pushing the boundaries of software development.
