<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>

<p><strong>Hreflang Customizer</strong> is a free plugin that generates hreflang tags for your WordPress pages automatically. It works on any site — no multilingual plugin is required.</p>
<p>Hreflang tags tell search engines which language and region each page targets. This prevents duplicate-content issues across multilingual or multi-regional sites and helps the right version of your page rank in the right country.</p>
<h4>Key Features</h4>
<ul>
<li>✅ Works <strong>without</strong> any translation plugin — standalone mode out of the box</li>
<li>✅ Also integrates with <strong>Weglot</strong> for translated URL mapping</li>
<li>✅ Searchable language picker with 180+ languages and regional variants</li>
<li>✅ Selected languages shown as removable tag chips with language codes</li>
<li>✅ Language list cached via WordPress Transients API (no repeated API calls)</li>
<li>✅ Clean, modern admin UI — fully responsive</li>
<li>✅ No upsells, no premium tier — 100% free</li>
</ul>
<h4>How It Works</h4>
<p><strong>Standalone mode:</strong> Select your target language codes in the settings page. The plugin outputs one <code><link rel="alternate" hreflang="..."></code> tag per selected code in the <code><head></code> of every page, pointing to the canonical URL of that page.</p>
<p><strong>Weglot mode:</strong> If Weglot is installed and active, the plugin maps Weglot’s translated URLs to your selected hreflang codes automatically.</p>
<h4>Example Output</h4>
<pre><code><link rel="alternate" href="https://yoursite.com/about/" hreflang="en-AU" />
<link rel="alternate" href="https://yoursite.com/about/" hreflang="en-GB" />
<link rel="alternate" href="https://yoursite.com/" hreflang="x-default" />
</code></pre>
<h4>Third-Party Service</h4>
<p>This plugin optionally fetches an extended language list from <strong>https://app.seo-hreflang.com/api/languages</strong> to supplement its built-in language database. The request is made at most once every 12 hours. No personal data, user data, or site content is transmitted — the request contains no body payload. The result is cached locally using the WordPress Transients API.</p>
<p>If the external service is unavailable, the plugin automatically falls back to its built-in list of 180+ languages and continues to work normally.</p>
