Case Study: Truely achieves consistent, high-quality localization across 32 languages with Lingo.dev

Truely streamlines 32-language localization with Lingo.dev

Truely, a travel platform, faced significant challenges managing content across 32 languages. They initially used raw OpenAI API calls, which resulted in poor quality, uncontrolled terminology, and an inability to maintain their brand voice. After finding human translators and platforms like Crowdin to be inefficient or overly complex, they turned to the localization engine from Lingo.dev for a solution.

Lingo.dev implemented a stateful localization engine that persisted Truely's glossary and brand voice configurations across all translation requests. This architectural shift ensured consistent terminology, natural-sounding translations, and text that automatically fit UI constraints. The results were immediate, with measurable quality improvements in languages like Dutch and Russian. The solution fully automated their translation process for 200 pages, freeing developers from management overhead and providing precise control across all 32 locales with zero ongoing configuration.
