It uses OpenAI models to interpret natural-language queries and suggest relevant shell commands.

Features

• Query for suitable commands using natural language
• Support for multiple shells (bash, zsh, cmd, PowerShell)
• Get explanations for commands
• Command history tracking for quick re-execution and recall
• Option to jump to the last command from history
• Simple config commands to set OPENAI_KEY, MODEL, and SHELL
• Persistent configuration storage
• Searched command stored in clipboard for quick execution
