1. GitHub Copilot X

If you are a developer and looking for the best AI coding tool, I highly recommend GitHub Copilot X. It’s an AI assistant that can help you with code completion, code explanation, debugging, and more. GitHub Copilot X is powered by the GPT-4 model, which is arguably one of the best general-purpose AI models out there. It’s even better than the purpose-built OpenAI Codex model, a descendant of the GPT-3 series.

Coming to features, GitHub Copilot X is intended to be your helpful AI pair rather than your replacement. It can integrate with every part of your workflow, offer contextual suggestions, fix a piece of code, translate code, write unit tests, and much more. You don’t even need to read the whole documentation. Copilot X can give personalized answers to your queries from the documentation.

It also keeps track of your pull requests and suggests descriptions around code changes to generate a comprehensive update of all the code merges. You can use Copilot X in your favorite Terminal or IDEs like VS Code, Visual Studio, JetBrains, Neovim, and more. Moreover, Copilot X supports several programming languages, including C, C++, C#, Go, Java, JavaScript, PHP, Python, Ruby, Scala, TypeScript, and more.

To quote some figures from Microsoft’s in-house research, Copilot X helped 74% of the developers focus more on satisfying work and 88% of developers felt more productive. In addition, for repetitive coding tasks, 96% of users were able to achieve them much faster with the help of Copilot X.

In summation, GitHub Copilot X can be your best AI coding assistant to tackle coding challenges. That said, keep in mind that Copilot X is not available to everyone currently. Individual users or businesses who already have GitHub Copilot can join the waitlist for Copilot X. Future pricing has not been decided yet, but Copilot costs $10 per month.

Codey is built on Google’s PaLM 2 model and supports only Python as of now. You can open Google Colab, launch a notebook, and check if a “Generate” button appears on top. The best part is that it’s free to use, however, paid Colab users will be first in line to get access.

Moving to Studio Bot, Google announced a similar AI companion for Android developers. You can use Studio Bot in Android Studio for developing Android apps. Again, the feature is rolled out to US developers first and other countries will get it gradually. Google says the technology is experimental, and it will slowly add new capabilities to the Bot. As for now, you can ask it to generate code, create test cases and update APIs for better compliance.
