# Server-Side Tools

> Capabilities Nito runs for the model during a call: web search, web fetch, and document parsing.

These are work Nito performs during your call and folds into the answer. Web search and web fetch are on by default; the flags narrow them or turn them off. Document parsing happens whenever you attach a file.

<CardGroup cols={2}>
  <Card title="Web Search" icon="magnifying-glass" href="/features/server-side-tools/web-search">
    Pull fresh information from the web into an answer. On by default. Narrow or disable it with `--web-search`.
  </Card>

  <Card title="Web Fetch" icon="link" href="/features/server-side-tools/web-fetch">
    Read a specific URL you name in your prompt into the model's context. On by default. Disable it with `--web-fetch=off`.
  </Card>

  <Card title="Document Parsing" icon="file-lines" href="/features/server-side-tools/file-parser">
    Attach a document with `--file` and Nito extracts its text so the model can read it.
  </Card>
</CardGroup>

## How They Fit Together

* **Web search** starts from a question and goes looking for sources.
* **Web fetch** starts from a URL already in your prompt and reads that one page.
* **Document parsing** starts from a file you attach and reads its text.

All three work on [`ask`](/commands/ask-and-continue), inside a [`session`](/commands/session), and from the [terminal](/cli/ask-and-fusion-from-terminal). For attaching images rather than documents, see [Image Input](/features/multimodal/image-input).
