One customiser can now serve shoppers in multiple languages. Add translations yourself or use AI to prepare a first draft, check each language in the live preview, and publish it when you are happy with the result.

Use AI to prepare first draft. Choose the source and target language and Sign Customiser fills the draft catalogue for you. The result stays private until you review it in the live customiser preview and choose to publish.
This is not a Shopify-only feature. The same published languages work across Universal customiser links, iframe embeds and supported custom element integrations. Universal sites can select a language explicitly, follow the site’s chosen language or use the shopper’s browser language before falling back to the customiser default. See how language selection works on Shopify and Universal, including the language_code URL parameter and language-code custom element attribute.
What’s Changed
- One customiser for every language - Add and manage languages without duplicating customisers or swapping template IDs for each market.
- Automatic language matching across Shopify and Universal - Shopify customisers follow the shopper’s active storefront language. Universal customiser links and embeds can use an explicit language, the site’s chosen language or the shopper’s browser language, with a safe fallback to your default.
- Manual or AI-assisted translation - Start with blank fields or ask AI to prepare a first draft. AI translations stay in draft until you review and publish them, and your manual edits remain protected.
- Private drafts and live previews - Work on a translation without changing the public customiser, then preview the real shopping experience before publishing.
- Full customiser interface coverage - Translate buttons, option names, choice labels, custom forms, warnings, review details, and other text within the customer customiser.
- Clear missing and stale translation notices - See what still needs attention and find wording that may need another look after you change the source language.
- Translated order details stay readable - Sign Customiser keeps the labels and choices the shopper saw with the product and order, while preserving the underlying details used for pricing and production.
