PolyTranslate AI for Polylang

⚠️ IMPORTANT: This plugin requires Polylang to be installed and active.

This is a third-party addon for Polylang – not affiliated with or endorsed by Polylang.

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

1. Polylang (required) – manages your languages and creates language versions
2. PolyTranslate AI (this addon) – automatically translates content between those languages
3. 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 Pro, 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.
