# Enable Translation API & Install Language Packs (Chrome built-in AI)

To ensure the Chrome Translator AI functions correctly, follow the steps below to enable the Translation API and install the required language packs:

## Step 1: Use a Secure Connection

First, make sure that your connection is secure; otherwise, Translation API will not work properly. If you’re using a non-secure (`http://`) site or localhost:

- Please switch to a secure connection (HTTPS) or add this URL to the list of insecure origins treated as secure by visiting [chrome://flags/#unsafely-treat-insecure-origin-as-secure](chrome://flags/#unsafely-treat-insecure-origin-as-secure). Click on the URL to copy it, then open a new window and paste this URL to access the settings.

## Step 2: Enable the Translation API

- Open this URL in a new Chrome tab: [chrome://flags/#translation-api](chrome://flags/#translation-api).

- Set the Experimental translation API option to Enabled.

- Click on Relaunch Chrome to apply the changes.

- The Translator AI model will now be enabled and ready for use.

Secondly, to translate between English (`en`) and Hindi (`hi`) or any other supported language, alternative language packs must be installed and supported. To view the list of supported languages:

- Please visit [chrome://on-device-translation-internals](chrome://on-device-translation-internals/) .

- Ensure your Chrome browser is updated to the latest version for optimal performance.

## Step 3: Install Language Packs

- You can install languages by visiting the following link: [chrome://on-device-translation-internals](chrome://on-device-translation-internals/).

- Please check if both your source (`en`) and target (`hi`) languages are available in the language packs list.

- You need to install both language packs for translation to work. You can search for each language by its language code: en and hi. After the language pack is installed, reload or restart your browser.

- Now, let’s add this language to your browser’s system languages in Chrome settings.

- Go to **Settings > Languages > Add languages** and add हिन्दी or English to your preferred languages list & reload the page.
