About this tool.
Hydori is the SEO + AI translation platform built for WordPress. Connect your site, choose your target languages, and Hydori translates your posts and pages into 20+ languages; then publishes them directly to WordPress as SEO-ready posts with hreflang tags, translated meta titles and descriptions, and proper source-translation relationships.
This plugin is the bridge between your WordPress site and the Hydori platform. It handles content export, translation delivery, SEO metadata sync, multilingual plugin wiring, and a live SEO and AI-readiness scoring panel inside the Gutenberg block editor.
The Problem Hydori Solves
Going multilingual on WordPress involves a lot more than translating text. You need hreflang tags set correctly so Google serves the right language to the right audience. You need translated meta titles and descriptions in your SEO plugin. You need multilingual plugins to recognise the posts as a translation group. You need slugs localised, categories mapped, featured images carried across, and brand terms left untranslated.
Most translation solutions stop at generating text and leave the rest to you. Hydori handles the full chain – from AI translation through to a properly published, SEO-configured WordPress post in every target language.
How Hydori Works
01Install and connect – Activate this plugin, visit Hydori & link your site.
02Choose your languages – Select target languages and a translation style (Professional, Casual, or Technical). Existing posts are indexed in Hydori automatically.
03Translate – Click Translate on any article, or bulk-translate your entire site in one action. Hydori’s AI handles the content while respecting your Brand Glossary terms.
04Publish – Translated posts are pushed to WordPress automatically as drafts or live posts, with SEO metadata, hreflang tags, featured images, categories, and multilingual plugin relationships all set.
05Track – Monitor translation status across every post and language from the Hydori dashboard: Done, Pending, Failed, or awaiting review.
Key Platform Features
AI Translation in 20+ Languages – Accurate, context-aware translations powered by AI, not word-for-word substitution
Translation Style Control – Choose Professional, Casual, or Technical tone per site
Brand Glossary – Define terms that must never be translated (product names, brand names, proper nouns)
Bulk Translation – Translate your entire site’s content in one action
Translation Status Dashboard – See every post’s status per language: Done, Pending, Failed, or Missing
Auto-Translate New Posts – Newly published WordPress posts are picked up and translated automatically
Require Review Mode – Translations arrive as drafts so your team can review before they go live
Team Collaboration – Invite team members with Admin, Editor, or Viewer roles
WordPress Integration Features
SEO Metadata Sync – Translated meta titles, descriptions, focus keywords, Open Graph tags, Twitter Card tags, and canonical URLs are written directly to Yoast SEO, Rank Math, All in One SEO, or SEOPress – whichever is active
Multilingual Plugin Integration – Translation relationships are created automatically as Source-Translation pairs along with an easy to digest admin panel view
hreflang Fallback – If no multilingual plugin is active, Hydori emits native rel="alternate" hreflang tags in <head> so Google still understands your language structure
Live SEO & GEO Scoring Sidebar – A panel in the Gutenberg block editor shows your SEO score (0-100) and AI-readiness grade (A-F) with per-check breakdowns and an editable focus-keyword field, fetched from Hydori and cached locally
Meta & Social Panel – Edit SEO title, meta description, Open Graph title, and Open Graph description directly in the block editor sidebar; changes are handed off to your active SEO plugin (or output directly by Hydori if none is installed) and protected from being overwritten by the next sync
Language Auto-Detect Banner – A small dismissible banner suggests a visitor’s browser-preferred language when a translation exists, without replacing the language switcher; on by default, can be turned off in Advanced settings
Score Columns in Posts and Pages List – SEO and GEO scores appear as colour-coded, sortable columns across your entire content library (green ≥80, amber 60-79, red <60)
Language Switcher Block – A native Gutenberg block that renders translation links on single posts and available languages on archive pages, with dropdown, list, inline, and button display styles
Localized Translation Slugs – Newly created translations use their own translated slug in the public URL (e.g. /fr/mon-article/) instead of the source article’s slug
Featured Image Sync – Images are downloaded and attached as post thumbnails on each translated post
Category and Tag Mapping – Categories and tags are created and assigned automatically during publishing
Auto-Export on First Connect – Existing published posts are indexed in Hydori in the background the moment you connect, with no manual action needed
One-Click Reconnect – After a plugin reinstall or key regeneration, the “Reconnect to Hydori” button re-syncs your site’s current API key back to Hydori without copying keys by hand
Clean Disconnect – Disconnecting from Hydori removes Hydori’s own bookkeeping for previously synced posts; your posts and translation groupings are never touched, so a later reconnect re-imports your full library instead of skipping posts as “already handled”
Secure API Key – Auto-generated on activation and stored securely in your WordPress database

Why Choose Hydori Over Other Translation Solutions?
Generic AI translation tools give you text. They do not set hreflang tags, do not write translated meta descriptions into Yoast, do not create source-translation groups, and do not preserve your brand terminology. You end up doing all the SEO configuration by hand, in every language, for every post.
Hydori handles the complete multilingual publishing chain. Translation, SEO metadata, hreflang tags, multilingual plugin relationships, featured images, categories, and tags – all delivered to WordPress in a single sync. And unlike per-word translation services, Hydori uses a credits-based lifetime deal so the cost does not grow with your content volume.

Frequently asked questions.
What is Hydori?
Hydori is an autonomous SEO platform that detects ranking issues, generates AI-powered content fixes, publishes them directly to your WordPress site, and proves which actions moved rankings. It handles the full SEO operations loop so you can focus on strategy instead of manual work.
How is Hydori different from Rank Math or Yoast?
Rank Math and Yoast are on-page SEO plugins that help you optimize individual posts inside WordPress. Hydori is a full SEO operations platform that works alongside them – it detects ranking drops across your entire site, generates AI content fixes, publishes updates directly to WordPress (with Yoast/Rank Math metadata filled automatically), and proves which fixes improved rankings. They complement each other.
Can I use my own OpenAI or Anthropic API key with Hydori?
Yes. Hydori supports BYOK (Bring Your Own Key) on all plans. Connect your own OpenAI or Anthropic API key and run unlimited AI operations at the provider’s cost instead of using Hydori credits.
How does Hydori prove that SEO fixes actually worked?
The Agentic Impact Scorecard tracks every fix and links it to specific ranking changes. It separates the effect of your actions from algorithm updates, seasonality, and competitor changes – so you can show exactly what worked. For example: “Content refresh on /blog/guide: +8 positions in 12 days.”
Can agencies use Hydori for multiple client WordPress sites?
Yes. The Scale plan supports 5 sites and the Command plan supports unlimited sites from a single dashboard. Command also includes white-label branded reports and client portals.
Does this plugin work on WooCommerce-powered sites?
Yes. If your site uses WooCommerce, Hydori can publish blog posts and pages to your WordPress site. The plugin currently supports the post and page post types. WooCommerce product descriptions (the product post type) are not supported at this time.
Can I edit my SEO title, meta description, and Open Graph fields directly in WordPress?
Yes. The “Meta & Social” panel in the block editor sidebar lets you edit the SEO title, meta description, Open Graph title, and Open Graph description for any post. Saving hands each value off to Yoast, Rank Math, All in One SEO, or SEOPress if one is installed; on a site with no SEO plugin, Hydori outputs the tags itself. Any field you edit in WordPress is protected from being overwritten by the next Hydori sync.
Does Hydori support Jetpack’s SEO fields?
Yes. Meta titles and descriptions also map to Jetpack SEO’s fields (advanced_seo_description, jetpack_seo_html_title), so sites using Jetpack’s SEO tools get Hydori’s meta description in their page’s meta description tag instead of falling back to the excerpt.
Is the WordPress plugin free?
Yes, the WordPress plugin is completely free. Hydori platform access is based on your subscription plan, starting at $79/month with a $5 trial available.
Which SEO plugins does Hydori work with?
Hydori automatically syncs SEO metadata with Yoast SEO, Rank Math, All in One SEO Pack, SEOPress, and Jetpack SEO. Meta titles, descriptions, and focus keywords are set during content publishing.
Which multilingual plugins are supported?
We support WPML, Polylang, and TranslatePress. Translation relationships are automatically created when you publish translated content, including proper hreflang tag configuration.
What happens to my synced posts if I disconnect from Hydori?
Disconnecting removes Hydori’s own bookkeeping for posts it has synced, but your posts, their content, and your translation groupings are never touched. This means if you reconnect later, your full library is re-imported instead of being skipped as “already handled.”
What happened to my API key?
The API key is automatically generated when you activate the plugin and stored securely in your WordPress database. If it is missing, click “Regenerate API Key” in the settings page.
Why am I getting 401 Unauthorized errors?
This usually means the API key in Hydori does not match your WordPress key. Go to Settings > Hydori, copy the current API key, update it in your Hydori dashboard, and click “Test Connection” to verify.
How do I troubleshoot connection issues?
Enable “Debug Mode” in Settings > Hydori Click “Test Connection” to see detailed results Check your WordPress debug.log file for entries starting with “Hydori” Contact support at hydori.io/contact if issues persist
Is my data secure?
Yes. The API key is stored securely in your WordPress database. All communication between WordPress and Hydori uses HTTPS encryption. Hydori never stores your WordPress credentials.
