Top 5 AI Code Generation Tools

Apr 11, 2024

With the advent of generative AI in the past year, the field of software development has profoundly changed. AI has significantly eased the coding process for professionals, streamlining complex tasks and enhancing efficiency. Now, even experienced developers can leverage AI to quickly generate code, boosting productivity and allowing more time for intricate problem-solving and innovation. 

Seasoned professionals can quickly stub out APIs in seconds. Beginners have a partner available 24/7 for code reviews and assessments. Even non-developers can release entire applications as long as they can sufficiently describe what they want in a prompt.

There are several AI code generation tools on the market and new ones are appearing every day, each with unique features and capabilities. Let’s take a look at some of the best and most popular options.

1. CoPilot by GitHub

Developed in collaboration with OpenAI, CoPilot by GitHub is a transformative code generator leveraging advanced language models like OpenAI's GPT-3 and Codex. It serves as more than just a coding assistant — it’s a virtual partner in programming. Here are its standout features:

  • Seamless Integration with popular IDEs: CoPilot sets itself apart with its integration into widely-used IDEs such as JetBrains, Neovim, Visual Studio, and Visual Studio Code. This integration facilitates a smooth coding experience, aiding in writing code, understanding complex codebases, and debugging.

  • Predictive code generation: At the heart of CoPilot's functionality is its predictive code generation, suggesting whole lines or blocks of code. This feature greatly accelerates the development process and is enhanced by its multilingual capability, thanks to training on a variety of public code repositories, which allows it to support numerous programming languages effectively.

  • Adaptive learning and security detection: GitHub’s Copilot doesn’t just follow a set pattern; it learns and adapts to individual coding styles, making its recommendations more personalized and accurate. It also includes the ability to detect security vulnerabilities, adding an extra layer of utility and safety to its coding assistance.

Copilot is available in three subscription tiers, ranging from $10 for individuals to $39 for enterprises. It also offers complimentary access for students, teachers, and open-source project maintainers, making it accessible to a wide range of users.

2. Replit GhostWriter

Replit GhostWriter  is an innovative tool designed to help programmers craft efficient, high-quality code. Here are its top three features that really make it stand out:
