hi-shell is a Go-based zsh plugin that suggests shell commands via LLM when you describe what you need, displaying suggestions as ghost text and blocking risky commands. Users type 'hi' followed by a description, review the suggestion, and optionally accept it with Tab or ask follow-up questions with 'hi?' or 'hi:'. It supports OpenAI, DeepSeek, and Claude as LLM providers with API keys stored as environment variables.
Guesswork is a zsh autosuggestion tool that uses an AI model to rank command suggestions instead of relying on simple prefix matching. Users can test the tool through a live demo that shows real model-based ranking for common commands like git, docker, and kubectl.
