Lionrapid – AI Translation & Multilingual SEO

Take your WordPress site multilingual and reach hundreds of millions of new customers, at a very affordable cost.

Lionrapid translates every page of your site and serves each language as a real page that visitors and search engines read. Install the plugin, click Connect, pick your languages: that’s the whole setup.

Why Lionrapid

• So easy. Install free from WordPress.org, click Connect to Lionrapid, choose languages on your dashboard. Set up in 5 minutes.
• Complete multilingual SEO. A URL per language (/fi/, /de/), hreflang with x-default, a canonical per language, the lang attribute, and translated titles, descriptions and social tags. Everything is rendered on the server, so Google, Bing and AI assistants read every language. Works alongside Yoast SEO, Rank Math, AIOSEO and SEOPress.
• Built for Elementor. Testimonials, counters, tabs, alerts, icon lists and accordions are translated, and your icons stay intact. Gutenberg and the classic editor too.
• Tested with 80+ of the most popular plugins. WooCommerce, Yoast SEO, Rank Math, Contact Form 7, WPForms, WP Rocket, LiteSpeed Cache, Jetpack, The Events Calendar and many more.
• Your forms keep working. Contact Form 7, WPForms and Fluent Forms keep every field in every language.
• Works with your page cache. WP Rocket, W3 Total Cache, WP Super Cache, LiteSpeed Cache, WP Fastest Cache, WP-Optimize, SiteGround Optimizer, Breeze and SpeedyCache are emptied for you when a translation changes.
• Fast. Pages are translated on your own server, from translations stored in your WordPress database, so a page never waits on us before it is sent, and visitors never see untranslated text flash on the screen.
• Quality you control. AI translation on models we host, automatic checks on every segment, and review by you or a professional translator before anything goes live. Fix any wording in place with the in-context editor.
• One memory for everything. Your site, documents and apps share one translation memory and termbase. Export them any time.
• The best value for money. Plans from €9.90 a month including VAT, with unlimited sites on every plan. A source word counts once against your served-word limit, however many languages you add.

Lionrapid: the choice of winners.

How it works

1. Install Lionrapid from Plugins → Add New (search “Lionrapid”) and activate it.
2. Under Settings → Lionrapid, click Connect to Lionrapid and approve it in your Lionrapid account.
3. Pick your languages on the dashboard. Your site follows at once: a language switcher, translated pages under /fi/, /de/ and so on, and hreflang for search engines.

New and changed text is collected automatically, translated, checked, and goes live when you approve it.

Pricing

The plugin is free and open source (MIT). Translation needs a Lionrapid plan:

• Basic: €9.90 a month incl. VAT, with 25,000 machine-translation words and 10,000 served words a month.
• Pro: €24.90 a month, with 100,000 and 50,000.
• Studio and Business for bigger sites.

Every plan includes unlimited sites, the translation memory and the termbase, and every paid plan starts with a 14-day trial. Cancel anytime. See https://www.lionrapid.com/pricing.

Key features

• Server-side translation: the page’s HTML is translated before delivery, so search engines see the translated content directly.
• Formatting kept: inline formatting such as <b> and <a> survives translation.
• Managed from the dashboard: source and target languages, the switcher and excluded paths come from your Lionrapid project. Changes are pushed to the site immediately, with a 5-minute check as a safety net.
• Gutenberg blocks: a translation block, a language switcher block and an inline translation editor.
• Language switcher: three styles (floating, buttons, flags), added to every page automatically or placed where you want it with the block.
• Language URLs: addresses like /de/, /es/ and /fi/ lead visitors to the right language.
• SEO: hreflang tags, translated meta descriptions and canonical URLs.
• New text is collected: text that appears on the live site is sent to your dashboard for translation in the background (wp_cron).

Required external service

This plugin requires a Lionrapid account. It connects to the Lionrapid service at the address shown under Settings → Lionrapid (https://app.lionrapid.com by default).

When activated and configured with a site key, the plugin sends:

• Translation requests (page content blocks) → server for translation lookup
• New keys discovered on the live site → server for translation queue
• Configuration sync requests → server for current project settings

Server endpoints called:

• GET /api/integrations/config?domain={your-site-domain} — fetches project config
• GET /api/integrations/translations/{locale}/{namespace} — fetches translations
• POST /api/integrations/sync/... — pushes newly discovered keys

When your settings hold a publishable key (pk_), your visitors’ browsers also call the Lionrapid service directly, at the API address your Lionrapid project gives (https://app.lionrapid.com by default):

• to load the translations and language settings for the page they are viewing;
• to report text on the page that has no translation yet, so it appears in your dashboard.

Like any web request, these calls show the service the visitor’s IP address and browser details. The plugin adds no tracking or analytics. Login and account pages excluded on the dashboard never report text. Without a publishable key, the browser loads translations from your own site instead and calls no Lionrapid address.

The plugin also adds two REST endpoints to your site:

• POST /wp-json/lionrapid/v1/resync: your Lionrapid dashboard calls it to push configuration changes immediately. It is authenticated with the key stored in your plugin settings.
• GET /wp-json/lionrapid/v1/api/integrations/translations/{locale}/{namespace}: public and read-only. It serves your site’s translations to the visitor’s browser, so the browser never needs a key.

Without a site key

Until you enter a site key, the plugin calls no external service. It does start preparing your pages for translation as soon as it is active (language links and markers in the HTML), so activate it once your Lionrapid account is ready.
