## LLM content visibility tags

ai, writing-content

New `<llms-only>` and `<llms-ignore>` tags let you provide additional context for AI assistants while keeping your documentation site (for human readers) clean and focused.

Use `<llms-only>` to show content exclusively to AI assistants via LLM endpoints (like `/llms.txt`) while hiding it from your documentation site:

**`docs/getting-started.mdx`**

```jsx docs/getting-started.mdx
<llms-only>
  This technical context is only visible to AI assistants via LLM endpoints.
</llms-only>
```

Use `<llms-ignore>` to show content only on your documentation site while excluding it from LLM endpoints:

**`docs/getting-started.mdx`**

```jsx docs/getting-started.mdx
<llms-ignore>
  <Callout intent="info">
    This callout appears on your documentation site but not in LLM endpoints.
  </Callout>
</llms-ignore>
```
