- tldr is great for quick examples of one command you already know the name of.
- ShellGPT and GitHub Copilot CLI are general assistants that can act for you, usually with a cloud model.
- TuxAide sits in between: it answers inside your shell, from a model on your computer, and leaves the running to you.
