Can you add i18n to an existing application without rewriting it?

Yes. We progressively extract hardcoded strings into translation keys, add the i18n framework, and migrate page by page. Your application remains functional throughout the migration.

How do you handle dynamic content like user-generated text?

User-generated content is stored in its original language. We implement language detection and optional machine translation via Google Translate or DeepL APIs for display purposes.

Do you support right-to-left languages like Arabic and Hebrew?

Yes. We implement full RTL support using CSS logical properties, MUI's RTL mode, and directional-aware icons. The layout automatically mirrors based on the active language direction.

Reach Global Audiences With Seamless Localization

Internationalization, right-to-left layouts, locale-aware formatting, and translation management. Bookuvai makes your application feel native in every language.

Feature: Multi-Language Support

Multi-language support (i18n/l10n) opens your application to global markets by adapting content, layouts, and formatting to each user's language and region. A proper implementation goes beyond string translation to include date/number formatting, RTL layout support, pluralization rules, and dynamic language switching. Bookuvai builds i18n systems that scale from 2 languages to 50+.
