## OpenAI Key

If you want AI-assisted translation, add your key to:

```bash {% title="apps/dev-tool/.env.local" %}
OPENAI_API_KEY=your-openai-api-key
```

## Where It Writes

Locale files live under:

```text
apps/web/i18n/messages/<locale>/*.json
```

The editor writes changes back to those files.

## Adding a Language

Add the locale to the i18n routing config first, then add the matching message files.
