About

Butterfish Shell is an open-source command-line tool that brings AI superpowers to your shell (bash, zsh) by integrating with OpenAI (or compatible APIs). It functions like GitHub Copilot for the shell, allowing users to prompt the AI by starting commands with a capital letter. The AI maintains context by seeing the shell history, enabling users to ask contextual questions like “Why did that command fail?” or request commands for specific tasks. Key features include GPT autosuggestion for commands, customizable and transparent prompts, support for various OpenAI models and compatible API providers, and a powerful “Goal Mode” where the AI acts as an agent to accomplish tasks by executing commands. Butterfish also offers other CLI utilities for prompting, summarization, command generation, and embedding management.

FAQs

What is this thing?

Butterfish is a command-line tool that adds AI prompting to your shell (bash, zsh) using OpenAI (or compatible APIs). It functions like GitHub Copilot for your terminal, providing contextual AI help.

What can you do with Butterfish Shell?

You can get commands for tasks, debug failures, run it as an agent (Goal Mode), receive shell command autocompletion, and use it as a general ChatGPT interface for diverse queries.
