Ch

Ch is a lightweight Go-based CLI tool for interacting with AI models directly from the terminal. It is the actively developed successor to Cha and focuses on faster startup, lower overhead, and better performance. The project is built for developers who want rapid AI assistance without opening a browser or using a heavy desktop app. It emphasizes transparent operations and user control, making it suitable for terminal-first workflows. Ch aims to preserve Cha’s core functionality while improving speed, packaging, and everyday usability. It is especially useful for programmers, system users, and productivity-focused terminal users who want an efficient AI assistant in their command-line environment.
