Mergy is a convenient browser extension that helps users combine contents from any public GitHub repository into a single text document. Designed for use with Anthropic's Claude Projects, Mergy simplifies the fetching, combining, and downloading of repository files. The tool ensures that the combined text is optimized for AI processing, making it easier for developers to provide context for entire codebases. Key features include customizable file inclusion/exclusion rules, respect for .gitignore rules, and support for custom ignore patterns. Mergy is especially useful for small to medium-sized libraries and requires a GitHub Personal Access Token for API access.
