Show HN: crai – Get notified when your AI CLI finishes thinking (github.com)

A new command-line interface (CLI) tool called "crai" has emerged, designed to notify users when their AI agents have completed processing a request. This tool engages with popular AI command-line tools such as Claude Code, Codex, and Gemini CLI, providing auditory alerts and visual notifications via macOS’s Notification Center. Crai monitors the output stream of AI tools, triggering a notification if there's a silence longer than 1500 milliseconds post-AI response, while intelligently ignoring any irrelevant output to maintain focus. This tool is significant for the AI/ML community as it enhances user experience during AI interactions by reducing the cognitive load of waiting for responses. With built-in features like echo suppression and quick-response suppression, crai allows seamless integration with existing workflows while maintaining robust notifications. Users can easily install crai via Homebrew or build it from source, making it accessible for developers seeking to streamline their AI tool usage. This innovation emphasizes the growing need for usability improvements in AI applications, fostering more efficient and engaging human-AI collaborations.
