# English Comment Classification

> How NAWA handles English comments - same API, same pricing, different routing.

# English comment classification

NAWA's API works for both Arabic and English comments. The same endpoints, same pricing, same response shape. The difference is under the hood: Arabic routes to ALLaM, English routes to Claude.

## How routing works

| Input language | Model        | Dialect detection                        | Pricing |
| -------------- | ------------ | ---------------------------------------- | ------- |
| Arabic         | HUMAIN ALLaM | Gulf, Egyptian, Levantine, MSA           | Same    |
| English        | Claude       | `null` (not applicable)                  | Same    |
| Mixed          | Claude       | Detected if Arabic portion is sufficient | Same    |

Language is auto-detected. You do not need to specify the language in your request.

## What changes in the response

For English comments, the `dialect` and `dialect_confidence` fields return `null`, and the `language` field returns `"en"`. Everything else is identical.

<CodeGroup>
  ```json Arabic response theme={null}
  {
    "intent": "question",
    "sentiment": "neutral",
    "dialect": "gulf",
    "dialect_confidence": 0.95,
    "language": "ar",
    "model": "nagl-v1"
  }
  ```

  ```json English response theme={null}
  {
    "intent": "question",
    "sentiment": "neutral",
    "dialect": null,
    "dialect_confidence": null,
    "language": "en",
    "model": "claude-v1"
  }
  ```
</CodeGroup>

## Multilingual channels

If your channel has both Arabic and English comments, you can send all comments through the same `/v1/classify` endpoint. NAWA detects the language automatically and routes accordingly.

```typescript theme={null}
// Works for both languages - no changes needed
const comments = [
  "This video was incredibly helpful, thank you!",
  "ما شاء الله عليك، محتوى رهيب!",
  "Can you make a follow-up on this topic?",
  "متى الجزء الثاني؟"
];

for (const text of comments) {
  const { data } = await nawa.classify({ text, platform: 'youtube' });
  console.log(`${data.language}: ${data.intent} (${data.sentiment})`);
}

// Output:
// en: praise (positive)
// ar: praise (positive)
// en: suggestion (neutral)
// ar: question (neutral)
```

## Reply generation

The `/v1/comments/:id/reply` endpoint also handles English. Arabic replies match the detected dialect. English replies are natural and platform-appropriate.

Set `language: "auto"` (default) to let NAWA match the commenter's language, or force a language with `language: "en"` or `language: "ar"`.

## Pricing

Pricing is identical for Arabic and English. No per-language surcharge.

| Endpoint | Cost    |
| -------- | ------- |
| Classify | \$0.006 |
| Reply    | \$0.008 |
| Detect   | \$0.002 |
| Moderate | \$0.004 |
