About this plugin
Translate your entire WordPress site effortlessly, without paying for expensive translation credits.
Auto AI Translator For WPML is a professional-grade bridge between your WPML setup and the world’s most advanced AI models. Instead of relying on rigid, word-for-word machine translation or purchasing marked-up translation credits, this plugin allows you to plug in your own OpenAI API key. It registers seamlessly inside WPML Translation Management, picking up your jobs, translating them with deep contextual awareness, and writing the polished results right back into your website.
We built this for real businesses and serious multilingual sites. When you have long-form content, complex page builder layouts, or thousands of products, you need a system that won’t break or time out.
Why choose Auto AI Translator?
- Zero Translation Markup: You use your own OpenAI API key. You pay OpenAI directly for what you use, saving you hundreds of dollars compared to traditional translation credits.
- Native WPML Integration: No new workflows to learn. Send jobs from the WPML Translation Management dashboard just like you always have.
- Smart Background Queue: Large posts are intelligently split into chunks. If a timeout occurs, the system retries and resumes exactly where it left off. You don’t even need to keep your browser tab open.
- Brand Voice & Glossaries: Enforce your brand’s tone of voice. Use global custom instructions to ensure specific industry terms, brand names, and product codes remain exactly as you want them.
- HTML & Page Builder Safe: It respects your formatting. Shortcodes, Elementor layouts, and complex HTML structures are kept perfectly intact during translation.
- Complete Transparency: A beautiful dashboard gives you a bird’s-eye view of your queue health, while per-job logs with timestamps show you exactly what is happening under the hood.
Requirements
- The WPML plugin (WPML Multilingual CMS + WPML Translation Management) with at least two active languages. WPML is a commercial plugin from OnTheGoSystems and is not included here.
- An OpenAI API key with billing enabled. Translation requests are billed by OpenAI directly to you.
External services
This plugin sends content to the OpenAI API in order to translate it. Nothing is sent anywhere else, and no data is sent to the plugin author.
- Service: OpenAI API ( https://api.openai.com/v1/chat/completions ).
- What is sent: the text of the field being translated (post title, content, excerpt, custom field or term name), the source and target language, and the translation instructions you configured. Requests are authenticated with the API key you enter in the plugin settings.
- When it is sent: only when a translation job is processed, either from the WPML queue, from the plugin queue, or when you re-translate a single item.
- Provider terms: OpenAI Terms of Use, OpenAI Privacy Policy, OpenAI API data usage.
No translation request is made until you save an API key, and the plugin makes no outbound request on activation.
