Free multilingual WordPress plugin — translate manually for free, or unlock unlimited automatic translation with a 7-day trial (no card required).

Perfecto Ramón Bouso Alvarez

TransLeti

The plugin is 100% free and GPL. You can run a fully multilingual WordPress site with manual translations, hreflang sitemap, language switcher and slug translation without ever paying anything or connecting to an external service.
If you also want automatic translation across every language at once, connect the optional Transleti API — flat-rate, unlimited words and languages, with a 7-day free trial. No card or payment method is required to start the trial, and the API is optional: the manual workflow keeps working forever, including after the trial ends, even if you never subscribe.
Transleti Translator handles posts, pages, custom post types, WooCommerce products, menus, slugs, SEO meta, and theme strings. A built-in visual editor lets you click on any text in the rendered page and refine its translation in a side-by-side panel — useful both for polishing automatic translations and for translating everything by hand.
<h4>Two ways to use it</h4>
<ul>
<li>Manual mode (free, forever) — edit each translation directly in the WordPress post editor or via the visual front-end editor. No API key, no subscription, no external connection required. Includes the language switcher, hreflang sitemap, slug translation and 49+ pre-defined language slots.</li>
<li>Automatic mode (optional Transleti API) — connect an API key and the plugin fans out translations to every target language in parallel. Flat-rate, unlimited words, 7-day free trial, no card required to start. If you decide not to subscribe after the trial, the plugin keeps working in manual mode. Manual edits on top of automatic translations are preserved on re-translation.</li>
</ul>
<h4>Features</h4>
<ul>
<li>Free GPL plugin — fully functional in manual mode without any external connection or paid service.</li>
<li>Visual translation editor — open any front-end page in an editor frame, click on any string (titles, paragraphs, menu items, buttons, image alts) and edit its translation in a side panel with live preview.</li>
<li>Manual translation editor — review and refine translations directly in the WordPress post editor for every language.</li>
<li>Optional unlimited automatic translation — flat-rate Transleti API subscription, 7-day free trial. No card or payment method required to start the trial; if you do not subscribe, the API simply stops at day 7 and the plugin keeps working in manual mode.</li>
<li>Parallel translation (API mode) — requests fan out to every target language simultaneously. A site with 10 languages translates in roughly the same time as a site with 1.</li>
<li>Built on open source — the plugin itself is GPL, fully auditable, no proprietary lock-in.</li>
<li>Theme-agnostic — works out of the box with Elementor, Gutenberg, classic editor, GeneratePress and any standards-compliant theme.</li>
<li>WooCommerce ready — translates product titles, descriptions, attributes and variations.</li>
</ul>
<h4>Key features</h4>
<ul>
<li>Multilingual sitemap with hreflang — separate <code><url></code> entries per language (the format Google explicitly documents) with self-referential hreflang and <code>x-default</code>. Compatible with Yoast SEO, RankMath, SEOPress, AIOSEO and the WordPress core sitemap.</li>
<li>SEO meta translation — titles and descriptions for SEOPress, Yoast, AIOSEO and RankMath.</li>
<li>Visual translation editor — open any front-end page in an editor frame, click on any string (titles, paragraphs, menu items, buttons, image alts) and edit its translation in a side panel with live preview.</li>
<li>Manual translation editor — review and refine translations directly in the WordPress post editor for every language.</li>
<li>Manual edit protection — your manual fixes survive re-translation cycles.</li>
<li>Slug translation — translated URLs (e.g. <code>/es/contacto/</code>) for clean per-language SEO.</li>
<li>Menu translation — duplicates and translates navigation menus per language.</li>
<li>HTML entity and shortcode protection — prevents corruption of <code>&copy;</code>, <code>[shortcode]</code>, and similar in translated output.</li>
<li>Custom “do not translate” word list — keep brand names, product codes and acronyms intact across all languages.</li>
<li>Language switcher — widget, block and shortcode in flag, dropdown or text styles.</li>
</ul>
<h4>Supported languages</h4>
49+ languages including English, Spanish, French, German, Italian, Portuguese (PT/BR), Dutch, Polish, Romanian, Bulgarian, Hungarian, Finnish, Russian, Ukrainian, Arabic, Hindi, Japanese, Korean, Chinese, Thai, Turkish, and more.
<h4>How it works</h4>
Manual mode (free):
<ol>
<li>Install and activate the plugin.</li>
<li>Choose your default language and the target languages you want to publish.</li>
<li>For each post / page, open the translation editor (in the post editor sidebar or via the visual front-end editor) and type the translation by hand.</li>
<li>The language switcher, hreflang sitemap and per-language slugs work out of the box.</li>
</ol>
Automatic mode (optional API):
<ol>
<li>Install and activate the plugin.</li>
<li>Sign up at https://transleti.com to get your API key (7 days free, no card required; the API stops automatically at day 7 unless you choose to subscribe).</li>
<li>Enter your Transleti API key in the plugin settings.</li>
<li>Choose your default language and the languages you want to publish.</li>
<li>The plugin runs a background job that translates posts, menus, slugs and SEO meta automatically.</li>
<li>Optionally refine any translation manually from the WordPress post editor — your edits are preserved on re-translation.</li>
</ol>
<h3>External Services</h3>
This plugin can optionally connect to the Transleti translation API (<code>api.transleti.com</code>) to translate site content automatically into the languages you select. This connection is optional — the plugin works in manual mode (typing translations by hand from the WordPress editor or the visual front-end editor) without contacting any external service. No external request is made unless you enter an API key in the plugin settings.
What data is sent (only in automatic mode): the text strings to translate (post content, titles, excerpts, menu labels, slugs, SEO meta, theme strings) along with the source and target language codes and your API key.
When it is sent: when the background translation cron runs, when you save a post that needs re-translation, or when you trigger a manual translation from the settings page.
Service provider: Transleti — <code>https://transleti.com</code>

No personal data of site visitors is sent to the service. Only the text content you choose to translate.
