Ask Command is an AI-powered macOS app that helps users remember and find Unix commands. It uses GPT-3 to generate command suggestions based on user queries. The app is designed to save time by providing quick reminders for commands, avoiding the need to search online. It is currently in beta, with a 30-day expiration, and is sandboxed for security, ensuring it cannot execute commands on your behalf. The app is not open source and only available for macOS.
