Features

Everything you need for multilingual WordPress

Built for sites with hundreds of pages and dozens of internal links.

Unique

Automatic Link Rewriting

Internal links are rewritten to point to the correct translated version of each page. No broken links, no manual fixes.

One-Click Bulk Translation

Server-side queue processes hundreds of pages without browser timeouts. Select, choose language, click Apply.

100+ AI Models

GPT-4o, Claude, Gemini, DeepSeek, Llama, Mistral — pick any model on OpenRouter. Switch anytime.

ACF Field Support

Advanced Custom Fields content — text, textarea, WYSIWYG — is translated alongside standard post content.

SEO-Friendly Slug Translation

Slugs are translated so URLs read naturally: /cloud-desktops/ becomes /fr/bureaux-cloud/.

Custom Post Types

Translate pages, posts, tutorials, FAQs, solutions, glossaries — any post type registered with Polylang.

Outdated Detection

Edit the original and translations are flagged as outdated. Know exactly what needs re-translating.

Custom Prompts

Control the AI: "Keep brand names in English," "Use formal German," "Match our casual tone."

Auto-Retry on Failure

API hiccups and rate limits are handled automatically. No babysitting bulk translations.

Drafts by Default

Every translation starts as a draft. Review and publish on your terms — nothing goes live without your approval.

Temperature Control

Slide lower for precise, literal translation. Slide higher for creative, natural-sounding output.

Media & Taxonomies

Featured images, categories, and tags are copied to translated posts. No manual re-assignment.

01

Install and activate

Upload the plugin zip to WordPress, activate it, and make sure Polylang is configured with your target languages.

Select pages from the list, choose a target language, and click Apply. The server-side queue handles hundreds of pages. Internal links are rewritten automatically. Review drafts and publish.

FAQ

Frequently asked questions

Yes. Polylang AI Translator extends the free Polylang plugin. Install Polylang first and configure your target languages. The free version of Polylang works fine — you don't need Polylang Pro.
You pay OpenRouter directly at their published rates. A typical 1,000-word blog post costs a fraction of a cent with GPT-4o mini, or a few cents with GPT-4o. Translating an entire 500-page site into 5 languages costs roughly $2–$10 in API fees. There is no markup — you pay exactly what OpenRouter charges.
WPML charges €199/year for their plugin, plus per-word translation credits that are marked up roughly 10x over raw API costs. A large site can easily spend $2,000–$4,000/year with WPML. Our plugin costs $49–$349/year with API costs at their true price. Plus, WPML requires migrating away from Polylang — a complex, risky process. We're Polylang-native.
Weglot uses a proxy approach — translations don't live in your WordPress database. Plans start at €190/year for 10K words. For a site with 1M+ words across 6 languages, you're looking at €2,990–€6,990/year. Our $199/year Growth plan covers 2M translated words, and the translations are real WordPress posts you own.
Any model available on OpenRouter: GPT-4o, GPT-4o mini, Claude 3.5 Sonnet, Gemini 1.5 Pro, DeepSeek, Llama 3, Mistral, and 100+ others. You can switch models at any time. Use budget models for bulk translation, premium models for important pages.
Yes. Text, textarea, and WYSIWYG fields from ACF are translated alongside standard post content. Other field types (images, numbers, relationships) are copied as-is.
When a page is translated, every internal link in the content is checked. If a translated version of the linked page exists in the target language, the link is rewritten to point to it. This happens automatically during translation — no extra steps, no manual checking.
You can upgrade your plan at any time. The word limit resets annually. Translated words are counted as source words multiplied by the number of target languages (e.g., 1,000 English words translated into 3 languages = 3,000 translated words).
Yes — your content is sent to the AI provider you select (OpenAI, Anthropic, Google, etc.) via OpenRouter's API for translation. Nothing is stored by the plugin. Review OpenRouter's privacy policy for details.
Yes. All plans come with a 30-day money-back guarantee. If the plugin doesn't work for your use case, contact us for a full refund.
