About this plugin
BallesDev LingoPress makes your WordPress site multilingual with a proven data model (languages and translation groups as taxonomies, no custom tables) and adds AI translation that actually understands your content. Every feature is included — there is no paid tier, license key or locked functionality.
Multilingual core
- Languages with directory-based URLs (/es/, /en/) and automatic rewrite rules.
- One post per language, linked as translation groups.
- Automatic hreflang tags, language-aware 301 canonicals and sitemap support.
- Language switcher as a Gutenberg block, shortcode, widget, menu item or PHP function.
- Menus per language, media translation with shared files, string translations.
- Template translations for block themes (FSE): each language gets its own copy of your templates and template parts.
- REST API: lang and translations fields on wp/v2, collection filtering with?lang=.
AI translation (optional)
- On WordPress 7.0+, LingoPress uses the AI provider you connected in Settings → Connectors through the WordPress AI Client — no extra API key in LingoPress.
- Or bring your own key: Claude (Anthropic), Gemini (Google), OpenAI (ChatGPT) and GroqCloud providers, selectable in settings (also on WordPress 6.5–6.9).
- Context-aware prompts: the AI reads the whole content, your site description and your glossary before translating a single word — so an ambiguous word like Spanish “muñeca” becomes “wrist” on a fitness blog, never “doll”.
- Glossary with hard terminology rules.
- One-click translation from the editor, bulk translation with a background queue, automatic retry with backoff on provider saturation, and outdated-translation detection with one-click re-translation.
- Long content is automatically split into block-aligned chunks.
- Every AI translation is created as a draft for human review. Nothing is published automatically.
The multilingual features work fully without any API key. AI translation is an optional extra that only runs when you ask for it — see “External services” below.

External services
LingoPress can translate your content with an AI provider of your choice. php ) — and a user with editing permissions starts a translation — from the post editor, the bulk action, the Queue, the Templates tab or the “Translate missing strings with AI” button. Queued jobs run in the background through WP-Cron, but only jobs that a user explicitly queued.
Only the provider selected in the settings receives data. Each request sends the text being translated (post title, content and excerpt; a theme template; or the registered strings), the source and target languages, your site name and tagline, the “Site context” and glossary settings, the post type and the names of the post’s categories and tags, together with your API key to authenticate. No other site or visitor data is sent.
- WordPress AI Client (Settings → Connectors) — used when the provider is set to “WordPress (Connectors)”. LingoPress hands the request to WordPress core, which sends it to the AI service the site owner connected (for example Anthropic, Google or OpenAI) under that service’s terms and privacy policy; LingoPress itself does not contact any external server in this mode.
