Features

Everything you need. Nothing you don’t.

Pure, purposeful, battle-tested on live Squarespace 7.1 sites.

  • The Ownership Advantage

    Subscription-based translation tools charge between $15 and $99 per month, meaning you could pay $1,000 or more over three years for a feature that the Squarespell plugin delivers as a permanent, one-time investment. When you purchase the Squarespell Language Switch Plugin, you own it. There are no renewal notices, no price increases, no features gated behind higher tiers, and no service cancellation risk.

  • SEO Compatible by Design

    The plugin is architected to remain invisible to search engines in a way that protects your existing SEO. It does not create duplicate pages, does not inject content in ways that confuse crawlers, and does not interfere with your existing metadata, canonical tags, or structured data. Your English rankings remain intact. Your site's authority is not diluted. The plugin enhances the user experience for human visitors while leaving your SEO infrastructure untouched.

  • Full RTL Language Support

    Arabic, Hebrew, Farsi, and Urdu are supported with right-to-left script compatibility. This is a non-trivial technical capability that most Squarespace translation solutions either ignore or handle poorly. The Squarespell plugin handles RTL language switching cleanly and professionally.

  • Geo Detection

    The plugin detects each visitor's country via IP geolocation on first visit and automatically switches the site to the appropriate language silently, instantly, and without any visitor action required. A French visitor lands on your French site. An Arabic speaker from the UAE lands on your Arabic version. This single feature alone has been shown to dramatically reduce bounce rates for international traffic.

  • 41 Languages. One Plugin. One Price.

    The plugin supports 41 of the world's most widely spoken languages covering billions of native speakers across every major region and market. From European languages like Spanish, French, German, Italian, Portuguese, Dutch, Polish, Swedish, Norwegian, Danish, Finnish, Czech, Romanian, Hungarian, Greek, Bulgarian, Croatian, Slovak, Lithuanian, Latvian, Estonian, and Catalan to major Asian languages including Chinese, Japanese, Korean, Hindi, Bengali, Vietnamese, Indonesian, Malay, and Thai to right-to-left script languages including Arabic, Hebrew, Farsi, and Urdu and extending further to Ukrainian, Russian, Turkish, Filipino, and more.

  • AI-Powered Multilingual Translator

    Turn your Squarespace website into a fully multilingual experience with support for 41 languages (including 4 RTL languages) complete with automatic geo-detection that switches content based on your visitor’s country.

What is the Squarespell Language Switch Plugin?

Still have a question? Email us →

How many languages does the plugin support?

The plugin supports 41 languages, including English, Spanish, French, German, Italian, Portuguese, Dutch, Polish, Russian, Ukrainian, Arabic, Chinese (Simplified), Japanese, Korean, Hindi, Bengali, Turkish, Vietnamese, Indonesian, Malay, Thai, Farsi, Swedish, Danish, Finnish, Norwegian, Czech, Romanian, Hungarian, Greek, Hebrew, Bulgarian, Croatian, Slovak, Lithuanian, Latvian, Estonian, Catalan, Filipino, and Urdu.

Is there a monthly subscription fee?

No. The Squarespell Language Switch Plugin is a one-time purchase. You pay once and own the plugin permanently. There are no monthly fees, annual renewals, usage limits tied to a paid tier, or subscription cancellation risks.

Does the plugin support right-to-left (RTL) languages?

Yes. The plugin fully supports RTL script languages including Arabic, Hebrew, Farsi (Persian), and Urdu, rendering them correctly within your Squarespace site layout.

Will the plugin affect my Squarespace SEO?

No. The plugin is designed to be SEO-neutral. It does not generate duplicate pages, does not modify your page URLs or canonical tags, and does not interfere with your existing metadata or structured data. Your English-language SEO rankings are fully protected.

How does geo-detection work?

On a visitor's first visit to your Squarespace website, the plugin detects their country via IP geolocation. If their country corresponds to a supported language (for example, a visitor from Japan is served Japanese, a visitor from Saudi Arabia is served Arabic), the plugin automatically switches the site to that language. The visitor's preference is then saved in their browser for all future visits.

Is the plugin mobile responsive?

Yes. The language selector widget is fully responsive and displays correctly across all screen sizes including desktop, tablet, and mobile consistent with Squarespace's own mobile-first design standards.

Can visitors manually choose their language?

Yes. In addition to automatic geo-detection, all visitors can manually select any of the 41 supported languages at any time using the floating language selector widget displayed on the site. Their selection is saved to their browser for future visits.

What happens if the primary translation provider is unavailable?

The plugin uses a three-provider waterfall architecture. If the primary translation provider reaches its daily capacity or is temporarily unavailable, the plugin automatically and silently switches to secondary and tertiary backup providers ensuring translation functionality is maintained without any visible interruption to your visitors.

Do I need any coding experience to install the plugin?

No coding experience is required. Installation involves copying the plugin script and pasting it into the Code Injection field in your Squarespace settings. The entire process takes approximately two to five minutes.

Is the plugin compatible with Squarespace carousels and slideshows?

Yes. The plugin includes a dedicated Carousel Engine that monitors Squarespace carousel components and re-applies translations as slides rotate. This is a specific technical feature addressing a known limitation in generic translation solutions used on Squarespace.

How quickly does the language switching happen?

For first-time visitors, translation begins streaming to the page as API responses arrive each element updates the moment its translation is ready rather than waiting for the full page. For returning visitors, all previously translated content is retrieved from the browser cache and painted to the DOM in under 16 milliseconds functionally instantaneous.
