The free edition (one post at a time, any language, no limits) is the one-button translator: download the free version and try it on your site first. Just one post to translate? Use the free online AI translator, no install. The full version adds bulk, SEO fields, terms, menus, WooCommerce and auto-translate.

Who it's for

WordPress site owners and agencies who publish in one language and want a fast, reviewable starting point in others — without pasting content in and out of a translation tool by hand, and without a monthly SaaS translation subscription.

What it does

A Translate box right in the post editor sidebar.
Pick a language and get a full draft translation of title and content in one click.
Preserves HTML markup, shortcodes and Gutenberg blocks — the draft stays structurally intact.
Every translation lands as a new draft post for human review before it goes live.
Built-in shortlist of high-demand languages (Arabic, Hindi, Chinese, Khmer, Swahili) plus any language by name.
Calls any text-capable AI endpoint compatible with the OpenAI chat completions API — OpenAI itself, or any compatible provider, including providers with free tiers.

The translation created as a separate draft post, headings, links and block markup preserved, ready for review

A WooCommerce variable product translated into Italian on the storefront: title, short description, Size and Color attributes, variation description and the header menu all in Italian

Appearance > Menus showing the Italian copy of the main navigation menu, with translated labels linking to the translated pages, category and shop

What the full version adds

The one-button translator is free on WordPress.org. The full version is for sites that translate a whole catalogue, not one post at a time:

Bulk translation: select any number of posts or pages in the list, choose Translate with AI, and they are translated into all your chosen languages in the background — no page left open, no timeouts.
SEO fields translated too: Yoast SEO and Rank Math titles, meta descriptions and focus keywords, plus the excerpt, so the translated page ranks in its own language.
Categories and tags translated once and reused, assigned to every translated post.
Outdated translations flagged and refreshed: edit the original and its translations are marked Outdated; re-translate them in place (one, a selection, or all) without losing their URL.
Polylang and WPML linking: if either is active, each translation (and each translated term) is registered as the translation of its source, so language switchers just work.
WooCommerce products: variations are recreated under the translation with price, SKU, stock and image; attributes and purchase note translated; up-sells and cross-sells point to translated products; stock stays in sync across every language.
Translated menus: copy a navigation menu into a language from Appearance > Menus (labels translated, links to translated pages), and each translated page shows the menu of its language.
Automatic translation on publish, with a glossary of brand names and terms to keep or translate your way.

BYOK (Bring Your Own Key): the plugin ships no API key of its own and does not act as a paid intermediary. No request is sent anywhere until you enter your own API key, and no post content passes through any server belonging to the plugin author — requests go directly from your site to the provider you configured.

What you get

The full-version plugin file (ai-translate-byok.zip) plus install instructions, delivered immediately after payment. It replaces the free version in place: same settings, no license key.

Installation

Upload the ai-translate-byok folder to /wp-content/plugins/.
Activate the plugin from the WordPress Plugins menu.
Go to Settings > AI Translate and enter your API key (and, if you're not using OpenAI, your provider's API base URL and model name).
Open any post, pick a target language and click Translate — a draft translation appears for review.

FAQ

Do I need an OpenAI key specifically?: No. Any endpoint compatible with the OpenAI chat completions API works — just change the API base URL and model in the settings.
Does the plugin publish the translation automatically?: No. Every translation lands as a draft for you to review and edit before publishing.
Does the plugin send my content to a server of its own?: No. Requests go directly from your site to the API provider you configured yourself.
Is there a free version?: Yes: the single-post translator, unlimited, with every language. The full version adds bulk translation, SEO and category translation and Polylang/WPML linking.
Is this a subscription?: No. $27.99 once. You only pay your AI provider directly, and only if their free tier doesn't cover your usage.
