WeLocale translates your website into 50+ languages with one connection. No code changes, no 
developer, live in minutes. Add your App Key and the WeLocale widget translates your site in 
place, with a built-in language switcher and SEO hreflang tags (on paid plans).
<ul>
<li>One connection, no code changes</li>
<li>50+ languages, AI-powered translations</li>
<li>Built-in language switcher</li>
<li>SEO hreflang tags (Pro and Scale plans)</li>
<li>Words are stored permanently and never reset monthly</li>
</ul>
You manage languages, translations, the switcher, and SEO in your WeLocale dashboard. This plugin 
only connects your site using your App Key; translations are stored in your WeLocale account, not 
in WordPress. The widget always loads its latest version from welocale.net, so improvements arrive 
without updating this plugin.
<h3>External service</h3>
This plugin connects your site to WeLocale (https://welocale.net), a third-party website-translation 
service, and requires a WeLocale account. When enabled, it loads the WeLocale widget script 
(https://welocale.net/widget/latest/loader.js) on your public pages using your App Key. The widget 
reads the visible text of your pages to translate it.

It’s even more useful if your own blog is multilingual.
