GitHub Chat integrates with various AI coding assistants like Cursor and Claude to facilitate instant understanding of codebases. It provides a straightforward API for indexing GitHub repositories and querying them for detailed information about their contents and technologies used. Unlike GitHub Copilot, GitHub Chat offers repository-wide analysis and a public API for developers.

Claude Code is a GitHub action that enhances PRs and issues by intelligently responding to context and executing code changes. It supports multiple authentication methods and includes features like code review, implementation of fixes, and seamless integration with GitHub workflows. The setup process is streamlined for users, providing various automation patterns and a comprehensive guide for migration and usage.
