# Captions & localize

> Generate platform-aware social captions and adapt creatives for multiple languages and markets using Captions and Localize in Creative Studio.

Creative Studio includes two copy and localization tools that keep your creative assets on-brand as they move across platforms and markets: **Captions** for social-ready post copy and **Localize** for multi-language adaptation.

## Captions — how do you generate platform-aware copy?

The Captions node generates polished post copy tailored to the platform and tone of your campaign. It reads from your creative context — product, brand identity, and brief — to produce copy you can use or refine immediately.

<Tabs>
  <Tab title="Instagram">
    Conversational, emoji-friendly, hashtag-rich copy optimized for feed posts and Reels captions. Tone defaults to engaging and aspirational.
  </Tab>

  <Tab title="TikTok">
    Short, punchy, trend-aware captions with hooks in the first line. Works well with on-screen text overlays.
  </Tab>

  <Tab title="LinkedIn">
    Professional, insight-led copy suited for B2B campaigns, brand storytelling, and thought-leadership ads.
  </Tab>

  <Tab title="Other platforms">
    Twitter/X, Facebook, Pinterest, and others. Tune tone and length to match each platform's conventions.
  </Tab>
</Tabs>

### Generating captions via MCP

Captions are available programmatically through the `generate_caption` tool in the ElarisLabs MCP integration.

```bash theme={"dark"}
generate_caption --platform instagram --tone engaging
```

## Localize — how do you adapt creatives for multiple markets?

The Localize node adapts your creative copy and assets for additional languages and regional markets, keeping visual identity and brand guidelines intact throughout the process.

### Supported locales

The app UI supports the following locales:

<CardGroup cols={4}>
  <Card title="English" icon="globe">en</Card>
  <Card title="Arabic" icon="globe">ar</Card>
  <Card title="Japanese" icon="globe">ja</Card>
  <Card title="Spanish" icon="globe">es</Card>
  <Card title="French" icon="globe">fr</Card>
  <Card title="German" icon="globe">de</Card>
  <Card title="Chinese" icon="globe">zh</Card>
  <Card title="More" icon="plus">Additional locales available</Card>
</CardGroup>

### How does localization stay on-brand?

<AccordionGroup>
  <Accordion title="Brand identity guidelines">
    Pair Localize with your brand's identity guidelines so tone-of-voice, terminology, and visual hierarchy carry through into localized assets. Set up your guidelines under [Brand identity](/docs/brands/identity-and-assets).
  </Accordion>

  <Accordion title="RTL layout support">
    Arabic (ar) and other right-to-left locales automatically adjust text direction and layout alignment in exported assets.
  </Accordion>

  <Accordion title="Review before export">
    Localized copy is always editable before export. Review translations in the Localize panel and make inline corrections without re-running the full generation.
  </Accordion>
</AccordionGroup>

<Tip>
  Run Localize **after** finalizating your master creative and captions in English. This ensures the source content is stable before spawning localized variants.
