Easily swap providers (IAssetProvider), create custom TMS integrations (ITMSService), or extend parsing logic.Build-Safe Architecture. Impossible to break your build. The tool creates a 'Safety Bridge' that automatically reverts localization previews before building or saving prefabs. Never accidentally commit localized text.🚀 Automation & ToolsMachine Translation Integration: Native support for DeepL, Google Translate, and Microsoft Translator with configurable batching. Plus, an AIPresetsGenerator to quickly set up popular AI services.Optimized Project Search: Instantly find any localized element in large projects without freezing the editor.Detailed Parsing Report: Track all added, updated, removed, and duplicate keys after every scan. Now includes detailed stats for Migrated and Skipped keys.Data I/O: Import & Export data in CSV, XML, YAML, and XLIFF formats, plus direct import from Google Sheets.One-Click Component Setup: Automatically add and configure all necessary localization components across your project.Backup System: Create, restore, and manage named backup copies of all localization data for ultimate safety.Asynchronous Operations: Optimized data loading and HTTP requests run in the background with a progress bar to keep the Editor responsive, even with large datasets.UI Layout Verification: New "Has Length Issues" filter automatically highlights translations that exceed the original text length by a specific % threshold, helping you spot UI overflows instantly.✨ Technical & Quality of LifeFull RTL (Right-to-Left) Support: Flawless rendering for languages like Arabic and Hebrew. Now uses reflection-based integration to eliminate compilation errors if the RTL asset is missing.Advanced Multi-line Editor: A pop-up window for editing long texts with a source text comparison, real-time placeholder validation, and a "Copy from Source" function.Smart Placeholder Protection: The system isolates placeholders ({0}) and line breaks from machine translators to prevent them from being damaged.Editor Crash Protection: If the Unity editor crashes while a preview is active (even in Prefab Mode), the tool automatically restores the original state of the objects on the next launch."Foolproof" Preview Protector: Automatically reverts changes from Live Preview before saving a scene or prefab to avoid accidentally saving temporary data.Non-Destructive Prefab Workflow: Keeps your original prefabs untouched for a safe, clean workflow. The localized prefab is created as a child object, while the original's components are disabled.Automatic Handling of "Play on Awake": Correctly handles localization for AudioSource, VideoPlayer, and other components with auto-play enabled.Secure API Key Storage: API keys are stored locally on your machine and are not committed to version control.Ready-to-Use Examples: Includes a drag-and-drop
