Rainline adds a floating translate button so shoppers read your storefront in their own language without leaving the page. It translates products, collections, navigation and blog text on demand - including third-party-app widgets and dynamically rendered content - and caches results for instant repeat visits. You stay in control: a glossary keeps brand terms consistent, style presets match your tone, setup is a theme app embed, no code. For SEO pages, pair with Shopify Translate & Adapt.

• Precision glossary: keep brand names or set fixed translations.
