AI Translation: localize any template in seconds

Translate your templates into any language with AI, right inside Courier Design Studio.

If you've ever localized a template, you know the process. Export strings, send them to a translation vendor, pay per word, wait, re-import, wire up locale logic, and hope nothing broke. Change one line of copy and you're doing it all again.

AI Translation is built into the Courier Design Studio. Pick a language, and AI translates your entire template in seconds. You review everything side by side, override anything that needs a human touch, and publish from the same editor you're already working in. It works across every channel: email, SMS, push, in-app, and chat.

How it works

You design your template once. AI localizes it into every language after that. Start by clicking the "Translations" Button

Add a locale

Open any template in Design Studio and click the globe icon in the toolbar. Pick a language from the searchable list, check "Translate with AI," and click Add. AI extracts every translatable string and translates it: subject lines, headings, body copy, button text, all of it. No separate internationalization pipeline, no string files to manage.

Review side by side

Your default content on the left, the translated version on the right, string by string. See how every piece of your template maps across languages, and preview the rendered translation before you publish.

Override anything

Every translated string is editable. Click into any field and write your own copy if the AI got something wrong or you want a different tone for a specific market. Your overrides persist even when you re-translate other strings in the same locale.

Smart variable placement

Dynamic variables like {user.name} or {order.total} get placed automatically based on the target language's grammar and word order. If the placement isn't right, move them yourself.

Stays in sync

Update your default template and Courier flags which translations are out of date. A warning indicator shows up next to each stale string. Re-translate only what changed with one click instead of re-doing the whole template.

Independent locales

Each language lives on its own. Translating into French doesn't touch your Spanish locale, and overrides in one language don't affect another. Add as many locales as you need, all from the same template.
