LangRelay – AI Translation & Multilingual vs International SEO by Transifex

LangRelay is a WordPress translation plugin that turns your site multilingual in minutes. AI translates every page, post, and product into 100+ languages. Translated URLs, hreflang tags, and a language switcher are handled automatically. Most translation plugins stop at the words on the page. LangRelay also translates your URLs, your meta titles and descriptions, and the llms.txt file AI search engines read, so your site gets found in every market you sell in. What you get AI translations that read like a human wrote them. Powered by frontier language models, not Google Translate. Translated URLs. yoursite.com/about-us becomes yoursite.com/nl/over-ons. Automatic hreflang. Hreflang tags, canonical tags, and language-specific sitemaps are injected for you. No manual setup. Translated SEO metadata. Meta titles, descriptions, and OG tags translate alongside the page. Works with Yoast and Rank Math. Language switcher. Dropdown, flags, or list. Available as a Gutenberg block, Elementor widget, shortcode, or auto-injected. Translated llms.txt. ChatGPT, Perplexity, and Claude can cite your site in any language you publish in. WooCommerce multilingual. Product pages, shop pages, cart, and checkout translate out of the box. Plays nice with caching. Compatible with WP Rocket, Cache Enabler, WP Optimize, and most other plugins. Why a multilingual WordPress site matters English is only 16% of the internet. The other 84% is your addressable market. Google ranks translated pages separately. A multilingual site can multiply your organic traffic without adding new content. AI search engines (ChatGPT, Perplexity, Gemini) increasingly answer questions in the user’s native language. Without translated pages, you don’t show up. How it works Install the plugin and connect your free LangRelay account. Pick the languages you want. LangRelay captures each page on first visit, translates it through the API, and serves the translated version. Subsequent visits are served from cache instantly. That’s it. No content duplication, no manual translation interface, no separate posts to manage. Multilingual SEO done right LangRelay handles the SEO work that usually takes hours per language: hreflang and x-default tags on every page Canonical tags pointing to the correct language version Translated slugs in the URL structure Language-specific XML sitemaps Translated meta titles, descriptions, and Open Graph tags Translated llms.txt for AI search engines Search engines understand which language to serve to which visitor. AI models cite your site across markets. What makes LangRelay different You only pay for the words that actually get translated. If the same sentence appears on 500 pages, you pay for it once. Most translation plugins count every word on every page, which adds up fast on larger sites. Switching from another translation plugin? Coming from a per-word service like Weglot, or a manual translation plugin like WPML or Polylang? Two things change: You stop paying per language. Per-word plugins multiply their word count by every language you add, so a 50,000-word site in five languages is billed as 250,000 words. LangRelay counts each source word once, no matter how many languages you publish. You stop maintaining translations by hand. There are no duplicate posts or separate editors to keep in sync. LangRelay translates each page on first visit and serves it from cache, so your content lives in one place. Keep your content, keep your domain, and go live in minutes. Pricing Free: 1 project, 1 language, 10K credits/mo Starter (EUR 19/mo): 3 projects, 3 languages, 150K credits/mo Growth (EUR 69/mo): 10 projects, 10 languages, 1.5M credits/mo Business (EUR 199/mo): Unlimited projects and languages, 15M credits/mo Annual billing saves ~17%. Full pricing at langrelay.com/pricing. How credits work One credit is one translated word. A 500-word page into one language costs 500 credits. Into three languages, 1,500. Credits only count the first time a piece of text is translated. If you update a paragraph on your homepage, only that paragraph uses credits again. The rest of the page stays as-is. Duplicate content (like your footer showing up on every page) is recognized and translated once. Credits reset every month and pool across all your projects.

Get Involved: Developers can contribute via the plugin’s GitHub Repository. Translators can contribute new languages to this plugin or our other WordPress plugins through Transifex. Minimum Requirements: WordPress 3.5.2 or greater PHP version 5.4.0 or greater MySQL version 5.0 or greater Tips for developers The Transifex Live plugin uses WordPress hooks to manipulate the links found in your website’s content, so they always point to the appropriate language. If you use custom post types (or one of your plugins does) that emits the ‘the_content’ filter, our code might not be triggered. For those cases, it is recommended to manually trigger our custom filter ‘tx_link’ before you return your content, as seen in the example below: Ex. $updated_content = apply_filters(‘tx_link’, $original_content); It is also recommended to use widgets in your theme instead of custom code, since this allows you to make your integration more future proof against incompatibilities with 3rd party modules.
