Lexis PRO

Documentation | Discord | Free Trial

Translate your game into any language — without leaving Unity.

Lexis PRO gives you everything you need to localize your game: manage translations, auto-translate with AI, sync with translators, and ship in as many languages as you want.

WHAT YOU CAN DO WITH LEXIS PRO

► Localize text across your entire UI

Built-in components for TextMeshPro, UI Toolkit, and Legacy UI. Add a component, pick a key, done. Text updates automatically when the player switches language.

► Localize images, audio, fonts, and prefabs

Swap sprites (flags, region-specific art), audio clips (voiceovers), fonts, and entire prefabs per language. One key, multiple assets — the right one loads for each locale.

► Manage translations in a visual editor

The String Table Browser gives you a fast, virtualized grid for thousands of entries. Search, filter, edit inline, and compare languages side by side.

► Import and export translations

JSON and CSV support out of the box. Hand off spreadsheets to translators, import them back, keep working. Version-control-friendly file formats that diff cleanly in git.

► Switch languages at runtime

One API call changes the language for your entire game. All UI components update instantly. Auto-detect the player's system language on first launch.

► Integrate with any architecture

Pure C# with zero MonoBehaviour dependencies. Works seamlessly with Zenject, VContainer, or any DI framework. Use the static API for quick access or inject ILocalizationService for testability.

► Auto-translate your entire game with AI

Connect to DeepL, ChatGPT, Claude, Google Translate, or Gemini — and translate all your strings in one click. Set your game's tone, genre, and glossary so translations match your style. Translation Memory caches results to save costs on retranslation.

► Collaborate with translators via Google Sheets

Let your translators work in Google Sheets while you stay in Unity. Pull and push translations with conflict detection and diff preview. No more emailing spreadsheets back and forth.

► Export to professional translation tools (XLIFF)

Send your strings to SDL Trados, memoQ, Phrase, Crowdin, or any TMS that supports XLIFF. Track translation states (Initial → Translated → Reviewed → Final).

► Use Smart Strings for dynamic text

Pluralization, gender agreement, number/date formatting, and conditionals — all built in. "{count:plural:one=# item|other=# items}" just works, with CLDR rules for every language.

► Find problems before your players do

Pseudo-localization reveals UI overflow and hardcoded strings. Unused Key Detection scans your entire project to find orphaned translations. The Validation System catches missing translations, broken keys, and formatting errors.

► Full RTL support

Arabic, Hebrew, Urdu, and Farsi work out of the box — bidirectional text, punctuation mirroring, and UI layout flipping included.
