Description
PolyTranslate AI is an independent addon that enhances your Polylang setup with automatic AI translation. While Polylang manages your multilingual structure, this addon handles the actual translation with just one click using premium AI services.
This is NOT a standalone translation plugin – it works exclusively with Polylang to add automatic translation capabilities.
🚀 How It Works
- Polylang (required) – manages your languages and creates language versions
- PolyTranslate AI (this addon) – automatically translates content between those languages
- Result: Complete multilingual site with minimal effort!
This plugin uses your own API keys to connect with top translation engines such as OpenAI (ChatGPT), DeepL, Google Translate, and OpenRouter. It makes it easy to translate your site’s content and metadata with a single click — directly within the WordPress admin.

FAQ
-
Does this work without Polylang?
-
No. This is an addon that adds automatic translation to Polylang. You must install and configure Polylang first. Without Polylang, this plugin will not function at all.
-
Why do I need both Polylang and this addon?
-
Polylang handles the multilingual structure (language management, URL structure, language switcher, manual translations).
PolyTranslate AI handles automatic content translation (AI-powered translation using OpenAI, DeepL, or Google). -
Is this an official Polylang product?
-
No. This is an independent third-party addon created to work with Polylang. We are not affiliated with or endorsed by the Polylang team. We simply integrate with their excellent language management system.
-
Will this work with Polylang Pro?
-
Yes! This addon works with both the free Polylang and Polylang Pro. It extends either version with automatic AI translation capabilities.
-
Is this plugin completely free?
-
The core plugin is free with powerful translation features. Premium features (ACF fields, bulk translation, advanced SEO support) require a license, but you’ll still save thousands compared to traditional translation methods.
-
Can I translate Advanced Custom Fields?
-
Yes! The premium version fully supports ACF fields including text, textarea, WYSIWYG, repeater fields, and more. Also supports Meta Box and other custom field plugins.
-
Is there a restriction on how many languages I can translate?
-
No. You can translate to as many languages as you want. Polylang handles the language management, and this addon translates content between those languages.
-
What happens if I uninstall the plugin? Do all translations get lost or are they still there?
-
All translations will still be there. This plugin only adds automatic translation capabilities. Once content is translated and saved, it becomes part of your WordPress database just like any other content.
-
Does this plugin support the classic editor?
-
Yes! This plugin works with both the Classic Editor and Gutenberg block editor.
-
Is my content secure?
-
Absolutely. Your content goes directly from your site to your chosen AI service using your API keys. We never see, store, or have access to your content or API keys.
-
Can I translate WooCommerce stores?
-
Yes! Both free and premium versions support WooCommerce. Premium adds product variations, categories, attributes, and advanced WooCommerce SEO meta translation.
-
Does it work with page builders?
-
Premium version supports Elementor fully. Gutenberg works out of the box. Other page builders work for basic content – contact us for specific compatibility questions.
