ShellGPT is a command-line productivity tool that generates shell commands, code snippets, and documentation by querying large language models directly from the terminal.
The tool solves the problem of context-switching to external resources when you need to recall command syntax or generate code. It accepts prompts via command-line arguments or stdin, making it easy to pipe data through it. By default it uses OpenAI's API with GPT-4, though it can be configured to run open-source models locally through Ollama. The tool is aware of your operating system and shell environment, so it tailors suggestions accordingly—for example, generating macOS commands when run on macOS and Ubuntu commands when run on Ubuntu. It supports major shells including Bash, Zsh, PowerShell, and CMD across Linux, macOS, and Windows.
Adoption requires an OpenAI API key and incurs API costs, though the README notes that open-source models can be run locally for free via Ollama as an alternative, with the caveat that the tool is not optimized for local models. The tool suits developers who frequently look up command syntax or need quick code generation and want to stay in the terminal. Shell integration via hotkeys in Bash and ZSH allows you to invoke suggestions directly into your terminal buffer for immediate editing, making it particularly useful for iterative command construction.
Development activity shows consistent engagement with bug fixes and feature refinements. The project maintains responsiveness to user-reported issues and incorporates feedback into updates. Documentation is actively maintained, including detailed guides for alternative setups like Ollama integration.
