Translate WordPress posts with OpenAI & WPML.
Translate one article or a batch, review the drafts, and keep each translation linked in WPML. The free plugin also translates supported Yoast SEO and Rank Math metadata and shows estimated OpenAI API costs.
Requires WordPress 6.5+, PHP 7.4+, active WPML Multilingual CMS and your own OpenAI API key. WPML is separate; OpenAI API usage is billed separately.

From content to translation in four steps
Activate WPML and configure your own OpenAI API key.
Choose the articles and target languages.
Start with one post as a draft, then translate larger batches.
Open the translated post from History, review it, then publish when ready.

Translate the post and its supported SEO metadata
When supported fields are present, Translation Assistant can translate Yoast SEO and Rank Math titles and meta descriptions alongside your post. Review those fields before publishing.
See your API usage
The dashboard shows input and output tokens and an estimated OpenAI API cost. The estimate helps you inspect usage; your OpenAI account remains the source of your actual charges.

Before you get started
Does this replace WPML or translate my entire site?
No. It works with WPML Multilingual CMS and focuses on WordPress posts and supported SEO metadata. Do not assume support for menus, WooCommerce products or every custom field.
Do I need WPML?
Yes. Translation Assistant is designed to work with WPML and requires WPML Multilingual CMS to be installed and active.
Do I need ChatGPT Plus?
No. This plugin uses the OpenAI API, which is separate from a ChatGPT subscription. You need API access and your own key; API usage may incur charges.
Do I need my own OpenAI API key?
Yes. You connect your own OpenAI API key in WordPress. OpenAI API usage is billed separately by OpenAI.
Can I translate multiple articles with the Free edition?
Yes. The Free edition supports on-demand bulk translation. Premium is focused on automation rather than unlocking bulk selection.
What does Premium add?
Premium is a separate add-on for translation triggered on publication and scheduled translation automations. Install the free plugin first and activate an authorized Premium license. WordPress scheduled tasks must run for automations to work. Bulk translation and full history remain available in Free.
How much does Premium cost?
Premium costs $4.99/month or $49.99/year for 1 site, $9.99/month or $99.99/year for 5 sites, and $19.99/month or $199.99/year for 25 sites. There is currently no lifetime license.
What happens if a translation already exists?
Translation Assistant checks WPML before creating a translation and can stop the operation when a translation already exists or is already being processed.
Start with one article. Keep control of the result.
Install the free plugin from WordPress.org and try one article as a draft. Add Premium later for translation on publication or recurring schedules.
