Smart Localization Suite

Translate your project without leaving Unity. Smart Localization Suite covers the full localization pipeline — string keys, API translation, coverage tracking, and CSV handoff to your translation team. Everything in one Editor window. One dashboard for everything Six dedicated tabs — Setup, Table, Scene, Coverage, Data Integrity, and Glossary. No scattered inspectors, no manual file management. 9 translation providers, no lock-in DeepL, Google Cloud, Azure, Amazon, IBM Watson, Yandex, Smartling, LibreTranslate, and MyMemory. Switch providers at any time without touching your data. MyMemory is free with no account required. Advanced provider options Each provider exposes its most powerful settings directly from Project Settings. Set a DeepL Formality Level per language, plug in your Azure Custom Translator Category ID for domain-specific models, or point LibreTranslate to your own self-hosted instance. Project Glossary Define your game's vocabulary once — skill names, lore terms, UI labels. Smart Localization Suite enforces them natively on DeepL via the Glossaries API, and injects them as context for every other provider automatically. Translate smarter Translate a single key, a selection, or your entire table in one click. Missing-only mode skips already-translated entries. A dry-run shows the character cost before any request is sent. Know your coverage before you ship The Coverage tab shows completion per language with a precise missing key list. Set the Build Validator to Strict and builds fail automatically if any language is incomplete. Data integrity built in Duplicate Detection, Safe Rename, and Orphan Scan keep your localization data clean throughout the project. All operations support full undo. Your translators don't need Unity Export to CSV or JSON, hand the file to your team, preview all changes with Import Preview, then import in one click. Secure by defaul tAPI credentials are stored in Editor-only assets and never included in builds. The Build Secret Guard validates this automatically at build time. Zero runtime footprint All tooling runs in Editor-only assemblies. No third-party packages required. Compatible with Unity 2021.3 LTS and later.
