How to set up
Translate your checkout content — product offers, widgets, validation messages, customization rules — into multiple languages for international buyers.
Works with Shopify Markets. The languages you can translate to are the ones you've already published in Shopify Admin → Settings → Languages. Add a language there first if it's not in the picker.
What it does
Translation lets you provide localized text for everything AOV.AI Checkout Upsell shows at checkout. When a buyer's checkout language matches one of your active languages, the app shows the translated copy. Otherwise, it falls back to the default text.
You can translate content in 8 areas:
Product Offers
Offer title, description, button label, variant label, quantity label
Custom Buttons
Section title, subtitle, per-button labels
Discount List
Section title, button label, expiry text, no-expiry text
Checkout Validation
Error messages (empty field, invalid format, etc.)
Checkout Customization
Renamed payment/delivery method names, shipping discount label
Testimonials
Verified badge, anonymous reviewer name, "Show more" / "Show less"
Trust Badges
Section heading, per-badge title and description
Custom Banners
Title, message (formatting like lists, bold, italic is preserved automatically)
Translations only ship to checkout for languages you've activated.
Step 1: Open Translation
In the app sidebar, click Translation. You'll see the Language List page.
The first row shows your Source language — usually English. This is the default text shown when no translation matches.
Step 2: Add a language
Click Add language (top right). A modal opens with all languages you've published in Shopify Markets.
Use the search box to filter by language name
Tick the languages you want to translate to
Languages already added show an "Already added" badge
Click Add to confirm
Newly added languages are active by default — they'll start being delivered to checkout as soon as you save translations.
Don't see a language? It needs to be published in Shopify Admin → Settings → Languages first. The banner inside the Add language modal links you straight to the right Shopify settings page.
Step 3: Toggle a language Active or Inactive
Each row in the language table has an Active toggle.
Active — translations for this language are shown at checkout
Inactive — translations stay saved, but checkout falls back to the default language for buyers using this language
Toggling takes effect at checkout within about a minute.
Step 4: Open the Translation Editor
Click Edit (or the language name) on any row to open the editor for that language.
The editor has:
Breadcrumb — Translation / Français
Auto Translate button (top right) — fills in all empty fields using AI
Tabs — one per content area (Product Offers, Custom Buttons, Discount List, etc.). Less-used tabs sit under More views
Side-by-side rows — default text on the left (read-only), translation input on the right
Step 5: Translate manually
Each tab groups content by entity (one accordion per offer, widget, or rule). Click a row to expand it.
Type the translated text in the right column. The completion count in the row header (for example, "3/5") updates as you fill in fields.
A few things to keep in mind:
If the original text contains a variable in curly braces (for example, the minimum or maximum amount in a validation error), keep it in your translation — use the Add variable button to insert it instead of typing it manually
For Custom Banner messages, type the translated message normally. Any formatting in the original (bullet lists, bold, italic) is preserved automatically — you don't need to copy the formatting marks yourself
Long text fields automatically expand to a multi-line text box
Saving:
A save bar appears at the top whenever you have unsaved changes
Click Save to persist. All edited fields across all tabs save together
All inputs disable while saving — wait for the toast confirmation before continuing
Step 6: Auto Translate (optional)
Click Auto Translate in the top right. A confirmation modal opens.
When you confirm:
The app sends all empty fields for the current language to AI in batches
A progress banner appears: "Translation is in progress and running in the background. You can safely leave this page and check back in 1–2 minutes."
AI fills in every empty field while keeping variables and formatting intact
Translations are saved and published to checkout
The banner clears and a "Last translated at …" badge appears
You can edit any auto-translated field afterwards — manual edits override the AI output.
Auto Translate is gated. If you don't see the button enabled, contact our support team — it requires a one-time activation per store. Use the Contact Support banner shown on the page.
Step 7: Verify on checkout
Open your store's checkout in a buyer's browser, switch the language using the Shopify language selector, and check that:
Offer titles, button labels, and widget content show the translated text
Validation errors (e.g. VAT field invalid) display in the buyer's language
Renamed payment/delivery methods show the translated name
Custom Banner formatting (lists, bold, italic) renders correctly
If something still appears in English, check that:
The language is Active in the Language List
The field actually has a translation saved (check the editor — empty fields fall back to default)
Delete a language
Click Delete on a row. A confirmation modal appears.
When you confirm, all translations for that language are removed from every offer, widget, validation rule, and customization rule. The change reaches checkout shortly after.
Deletion is permanent — re-adding the language won't restore the previous translations.
How language fallback works
Matches an Active language with a saved translation for the field
Translated text
Matches an Active language but the field has no translation
Default (source language) text
Matches an Inactive language
Default text
No match (e.g. buyer uses a language you haven't added)
Default text
The app matches by main language, not region. A buyer using French (Canada) sees your French translation — you don't need to add separate translations for French (Canada) and French (France) unless you actually want different copy.
FAQ
Q: Do I need Shopify Plus? A: For the translations to actually show at checkout, yes — the checkout features that render translated content require Shopify Plus. The Translation admin UI works on any plan.
Q: Can I import/export translations as CSV? A: Not yet. CSV bulk import/export is on the roadmap.
Q: Does Auto Translate work with the formatting in Custom Banner messages? A: Yes. The AI is instructed to keep all formatting (bullet lists, bold, italic, line breaks, links) intact while translating only the words.
Q: What happens if I deactivate a language with translations saved? A: Translations stay in the database. Checkout immediately stops showing them — buyers using that language see the default text again. Toggle it back to Active any time.
Q: Why isn't Image Carousel in the tab list? A: Image Carousel doesn't show any text content visible to buyers. There's nothing to translate.
Q: Can I have one language fall back to another (e.g. French Canada to French France)? A: No. The app matches by main language only. Either there's a translation for that language or it falls back to the default — there's no per-region inheritance.
