Microsoft-owned GitHub today launched its Copilot AI tool. This tool helps developers suggest code lines to their code editor. 

OpenAI and GitHub teamed up to create a preview version of Copilot last year. It's now available for all developers.

GitHub Copilot costs $10 per month and $100 annually. It can suggest the next line of code to developers as they type in an integrated development environment, such as Visual Studio Code, Neovim, or JetBrains IDEs. 

Copilot can suggest complex algorithms and complete methods, as well as boilerplate code and support with unit testing.

Over 1.2 million developers have signed up for the GitHub Copilot Preview over the past 12 months. It will continue as a free tool for verified students or maintainers of popular open-source projects.

GitHub claims that nearly 40% of the code being written now is by Copilot in files where it is enabled.

"Just as the rise of compilers, open-source, and AI-assisted coding will fundamentally alter the nature of software engineering, giving developers a new tool that allows them to write code faster and easier so they can live happier," states Thomas Dohmke, CEO of GitHub.

GitHub Pilot is now available to all developers and comes with a free 60-day trial. GitHub will soon offer Pilot to businesses.
