GitWit is an AI-powered tool that enables developers to speed up their coding process using natural language to prompt code generation and modification. It integrates with modern developer tools and utilizes large language models to create and modify codebases with a single prompt. Aimed primarily at full-stack developers with a learning mindset, GitWit is currently in beta, offering up to five free projects and unlimited revisions. The tool uses GPT-4 to generate code and track changes and requires a GitHub account to access.
