Lightweight localization for Unity—no Addressables required, but supported.
Smart strings, TextMeshPro & UI Toolkit support, RTL languages. Set up in minutes.Documentation | Discord | Free TrialTranslate 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► Auto-translate your entire game with AIConnect 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 SheetsLet 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).► Localize text, images, audio, fonts, and prefabsNot just strings — swap sprites, audio clips, fonts, and entire prefabs per language. Built-in components for TextMeshPro, UI Toolkit, and Legacy UI that update automatically when the player switches language.► Use Smart Strings for dynamic textPluralization, 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 doPseudo-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 supportArabic, Hebrew, Urdu, and Farsi work out of the box — bidirectional text, punctuation mirroring, and UI layout flipping included.━━━━━━━━━━━━━━━━━━━━━━━━━━━━EDITOR TOOLS• String Table Browser — fast, virtualized grid for thousands of entries with inline editing and side-by-side language comparison• Translation Window — translate, configure services, and manage translation memory in one place• Language Switcher — instantly preview your game in any language• Source Quality Checker — catch hardcoded strings and formatting issues in your source text• Import/Export — JSON, CSV, PO (GNU Gettext), XLIFF, and Google Sheets━━━━━━━━━━━━━━━━━━━━━━━━━━━━WHY LEXIS INSTEAD OF UNITY LOCALIZATION?✓ No Addressables dependency — simpler setup, fewer build headaches✓ 5-minute setup — drop in, configure, start localizing✓ Pure C# — works with Zenject, VContainer, or any DI framework✓ Full source code included — debug, extend, and customize anything✓ Zero-allocation formatting with ZString integration━━━━━━━━━━━━━━━━━━━━━━━━━━━━WORKS WITH• Unity 2020.3 LTS and newer• All platforms: PC, Mobile, WebGL, Consoles• All render pipelines: Built-in, URP, HDRP• Optional: TextMeshPro, UI Toolkit, Addressables, UniTask, ZString━━━━━━━━━━━━━━━━━━━━━━━━━━━━FREE VS PROThe free edition includes core localization, Smart Strings, JSON/CSV support, and all UI components.PRO adds: AI translation (5 services), Google Sheets sync, XLIFF export, PO support, Pseudo-localization, Unused Key Detection, Validation, Translation Memory, File Watching, RTL support, Addressables integration, and full source code.Lexis PRO - Complete Feature ListCore Localization (fully functional, no limits):- Unlimited translation keys- Unlimited supported locales- JSON and CSV file format support (read/write)- TextMeshPro integration with per-locale font overrides- UI Toolkit integration with UXML attributes- Full RTL (right-to-left) and bidirectional text support- Smart Strings: pluralization, gender, conditionals, number/date/currency formatting- System locale auto-detection- Locale-aware formatting (CultureInfo)- Event-driven architecture (OnLocaleChanged, OnLocalizationReady)- Zero MonoBehaviour dependencies — DI-friendlyPro-Exclusive Features:- Google Sheets sync (Pull/Push) with bi-directional collaboration- XLIFF provider for professional TMS integration (memoQ, SDL Trados, Phrase, Crowdin, Lokalise)- PO/Gettext provider for GNU standard i18n workflows- Auto-Translation: DeepL, OpenAI GPT, Google Translate APIs- Batch translation with progress tracking and translation memory- Sync operations (Pull/Push) with conflict detection and safety dialogs- File watching for live reload during development- Validation system: missing translations, unused key detection- Unused Key Detection CI/CD tool with exit codes and JSON reports- Pseudo-localization testing for UI layout verification- Source quality checker (spell check, grammar, placeholder consistency)- Addressables integration for async asset management- Localization key search windows- Full source code includedRuntime Components:- LocalizedTMP (TextMeshPro)- LocalizedLabel (UI Toolkit)- LocalizedText (Legacy UI)- LocalizedImage (locale-specific sprites)- LocalizedAudio (localized audio clips)- LocalizedTexture (localized textures)- LocalizedPrefab (localized prefabs)- LocalizedFont / LocalizedLegacyFont- RtlLayoutGroup (automatic layout flipping)Editor Tools:- String Table Browser with virtualized scrolling- In-editor Language Switcher- Setup Wizard with integration detection- JSON and CSV Import- Inspector property drawers with key dropdowns- Multi-table workflowsShared Features (also in Free):- Unlimited translation keys and locales- JSON and CSV file format support- TextMeshPro integration with per-locale fonts- UI Toolkit integration with UXML attributes- Full RTL (right-to-left) language support- Smart Strings: pluralization, gender, conditionals, number/date formatting- System locale detection- Event-driven architecture (OnLocaleChanged, OnLocalizationReady)- Zero MonoBehaviour dependencies — DI-friendly- String Table Browser with virtualized scrolling- In-editor Language Switcher- Setup Wizard with validation- JSON and CSV Import & Export- All runtime components (LocalizedTMP, LocalizedLabel, LocalizedText, etc.)- All localized asset types (sprites, audio, textures, prefabs, fonts)Compatibility:- Unity 2020.3 LTS through Unity 6- All platforms: Windows, macOS, Linux, Android, iOS, WebGL- All render pipelines: Built-in, URP, HDRPDependencies:- Required: Unity 2023.1+ OR UniTask- Optional: TextMeshPro, UI Toolkit, ZString, AddressablesDocumentation:- Setup guide included- Code samples and API reference- Full Documentation- Online Reference- Priority supportAi supported code generation
