# Using the CLI

> Whether you need the nito CLI, what it is for, and how it relates to the in-chat plugin.

Questions about the terminal side of Nito. See the [CLI](/cli/reference) section for the full reference.

#### Do I need the `nito` CLI at all?

No, not for everyday prompting. The plugin does the work from inside your chat. The [CLI](/cli/reference) is there for installing and repairing the integration, and for running Nito from the terminal or a script when you want to.

#### What can I do from the terminal that I cannot do in a chat?

Install and authorize a harness (`nito setup`), check the health of your setup (`nito doctor`), keep everything current (`nito update`), and start a fully Nito-routed session from a script. See [CLI Overview](/cli/reference).

#### Can I ask a question without opening a chat?

Yes. `nito ask "your question"` prints an answer and exits, and `nito fusion` runs a multi-model Fusion. See [Ask and Fusion](/cli/ask-and-fusion-from-terminal).

#### A command says Nito is not connected. What do I do?

Run `nito doctor` to see what is wrong, `nito agent login` to sign in, then re-run your command once. See [Doctor and Update](/cli/doctor-and-update) and [Troubleshooting](/help/troubleshooting).
