<p><strong>PiedWeb AI Polyglot</strong> is the multilingual infrastructure for your WordPress + WooCommerce site — routing, SEO, admin UI, virtualized stock and reviews — without duplicating content. It does <strong>not</strong> translate text itself: you bring your own translation provider (an LLM, a translation API, or a human translator), and the plugin handles everything else.</p>
<p>It uses a <strong>Master/Shadow architecture</strong>: you manage content in your primary language, and the plugin creates linked shadow copies for each target locale. Each language gets its own domain (or subdomain), with full SEO support out of the box. WP-CLI commands expose the master content as JSON so you can pipe it into any LLM or translation API and push the result back.</p>
<p>Designed to fit AI-powered translation workflows — but works just as well with human translators or a flat-file editing loop.</p>
<h4>Why PiedWeb AI Polyglot?</h4>
<ul>
<li><strong>No content duplication</strong> — shadows are linked copies, not clones. Update the master, shadows follow.</li>
<li><strong>No separate database</strong> — everything lives in a single WordPress install. No sync headaches.</li>
<li><strong>No performance penalty</strong> — stock, images, and reviews are virtualized at query time, not copied.</li>
<li><strong>No plugin lock-in</strong> — all data is stored as standard WordPress post meta. Remove the plugin, your content stays.</li>
<li><strong>AI-ready</strong> — WP-CLI commands expose master content as JSON, ready to pipe into any translation API or LLM.</li>
</ul>
<h4>Features</h4>
<ul>
<li><strong>Domain-based routing</strong> — one domain per language, detected via <code>HTTP_HOST</code>. Each domain serves only its locale’s content.</li>
<li><strong>Virtualized stock</strong> — shadow products read stock from the master in real time. Orders on any domain decrement the same inventory.</li>
<li><strong>Virtualized reviews</strong> — reviews submitted on any domain are stored on the master product. Star ratings are aggregated across all locales.</li>
<li><strong>Virtualized images</strong> — shadow products inherit the master’s featured image and gallery without duplicating media files.</li>
<li><strong>Hreflang SEO</strong> — automatic <code><link rel="alternate" hreflang="..."></code> tags plus sitemap annotations with <code>xhtml:link</code>.</li>
<li><strong>Locale-filtered sitemaps and RSS</strong> — each domain’s sitemap and feed only expose its own content.</li>
<li><strong>WooCommerce i18n</strong> — shipping labels, checkout legal texts, cart product names, and permalink slugs are all translated per locale.</li>
<li><strong>Human lock</strong> — manually edited translations are protected from automated overwrite (unless you <code>--force</code>).</li>
<li><strong>Language suggestion banner</strong> — auto-detects the visitor’s browser language and suggests switching locale, with dismiss + localStorage persistence.</li>
<li><strong>Draft link handling</strong> — internal links pointing to drafts are auto-hidden for public visitors and re-activate once the target is published. Editors keep working links.</li>
<li><strong>Language switcher</strong> — drop-in function for your theme with WooCommerce cart session transfer across domains.</li>
<li><strong>Admin UI</strong> — locale filter dropdown, language badge column, shadow warning banner, and translations metabox on masters.</li>
<li><strong>Flat-file export/import</strong> — bulk export all translations to TSV + HTML files, edit offline, re-import.</li>
<li><strong>WP-CLI powered</strong> — list untranslated content, push translations, manage slugs — all from the command line.</li>
</ul>
<h4>Works without WooCommerce</h4>
<p>All WooCommerce features (stock, reviews, cart, slugs) activate only when WooCommerce is present. On a standard WordPress site, the plugin handles routing, hreflang, admin UI, and translation management with no extra dependencies.</p>

PiedWeb AI Polyglot

Multilingual infrastructure for WordPress + WooCommerce. One install, one database, zero duplication. Bring your own translator (AI or human).

langrelay

<p>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.</p>
<p>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.</p>
<h4>What you get</h4>
<ul>
<li><strong>AI translations that read like a human wrote them.</strong> Powered by frontier language models, not Google Translate.</li>
<li><strong>Translated URLs.</strong> <code>yoursite.com/about-us</code> becomes <code>yoursite.com/nl/over-ons</code>.</li>
<li><strong>Automatic hreflang.</strong> Hreflang tags, canonical tags, and language-specific sitemaps are injected for you. No manual setup.</li>
<li><strong>Translated SEO metadata.</strong> Meta titles, descriptions, and OG tags translate alongside the page. Works with Yoast and Rank Math.</li>
<li><strong>Language switcher.</strong> Dropdown, flags, or list. Available as a Gutenberg block, Elementor widget, shortcode, or auto-injected.</li>
<li><strong>Translated llms.txt.</strong> ChatGPT, Perplexity, and Claude can cite your site in any language you publish in.</li>
<li><strong>WooCommerce multilingual.</strong> Product pages, shop pages, cart, and checkout translate out of the box.</li>
<li><strong>Plays nice with caching.</strong> Compatible with WP Rocket, Cache Enabler, WP Optimize, and most other plugins.</li>
</ul>
<h4>Why a multilingual WordPress site matters</h4>
<ul>
<li>English is only 16% of the internet. The other 84% is your addressable market.</li>
<li>Google ranks translated pages separately. A multilingual site can multiply your organic traffic without adding new content.</li>
<li>AI search engines (ChatGPT, Perplexity, Gemini) increasingly answer questions in the user’s native language. Without translated pages, you don’t show up.</li>
</ul>
<h4>How it works</h4>
<ol>
<li>Install the plugin and connect your free LangRelay account.</li>
<li>Pick the languages you want.</li>
<li>LangRelay captures each page on first visit, translates it through the API, and serves the translated version. Subsequent visits are served from cache instantly.</li>
</ol>
<p>That’s it. No content duplication, no manual translation interface, no separate posts to manage.</p>
<h4>Multilingual SEO done right</h4>
<p>LangRelay handles the SEO work that usually takes hours per language:</p>
<ul>
<li><code>hreflang</code> and <code>x-default</code> tags on every page</li>
<li>Canonical tags pointing to the correct language version</li>
<li>Translated slugs in the URL structure</li>
<li>Language-specific XML sitemaps</li>
<li>Translated meta titles, descriptions, and Open Graph tags</li>
<li>Translated llms.txt for AI search engines</li>
</ul>
<p>Search engines understand which language to serve to which visitor. AI models cite your site across markets.</p>
<h4>What makes LangRelay different</h4>
<p>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.</p>
<h4>Pricing</h4>
<ul>
<li>Free: 1 project, 1 language, 10K credits/mo</li>
<li>Starter (EUR 19/mo): 3 projects, 3 languages, 150K credits/mo</li>
<li>Growth (EUR 69/mo): 10 projects, 10 languages, 1.5M credits/mo</li>
<li>Business (EUR 199/mo): Unlimited projects and languages, 15M credits/mo</li>
</ul>
<p>Annual billing saves ~17%. Full pricing at <a href="https://langrelay.com/pricing" rel="nofollow ugc">langrelay.com/pricing</a>.</p>
<h4>How credits work</h4>
<p>One credit is one translated word. A 500-word page into one language costs 500 credits. Into three languages, 1,500.</p>
<p>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.</p>
<p>Credits reset every month and pool across all your projects.</p>
<h4>Meet Relay</h4>
<p>Relay is your AI assistant inside the LangRelay dashboard. Ask it about translation coverage, quality scores, or which pages still need attention. It pulls live data from your project so you don’t have to dig through the user interface.</p>
<h4>External services</h4>
<p><strong>LangRelay API</strong></p>
<p>This plugin sends page HTML to the LangRelay API for translation. Data is sent over HTTPS. Your WordPress database is never modified.</p>
<p>What is sent: page HTML, your authentication token, target language code.<br />
When: on untranslated or uncached page requests, during setup verification, and when syncing project settings.</p>
