Command-G is a tool designed to serve as a versatile Xcode copilot for developers working on iOS, macOS, and visionOS. Its functionalities are centered around aiding developers with coding tasks and workflow efficiency.

One of the notable features of Command-G is its code auto-complete capability which aims to accelerate coding tasks and inspire developers during their programming process.

This feature is powered by Codeium. Another feature is its integration with ChatGPT, allowing code to be inserted as context in conversations with ChatGPT to facilitate communication and ensure better focus during coding tasks.

The tool also carries a robust focus on personal security and privacy, with measures in place that prevent Command-G servers from accessing user code or messages, and no telemetry to track app usage.

While it offers various licenses for different types of users, such as trial users, early adopters, and individual developers, each type is subject to certain conditions and features.

Command-G is developed by Olivier Truong who has a background in iOS development and financial infrastructure design.
