Mac
Localize your Xcode app in minutes. AI translates String Catalogs into 24 languages — placeholders stay valid, plurals stay correct, your code stays private.
Translate your iOS or macOS app into 24 languages in minutes. StringWise is the AI localizer for Xcode that handles String Catalogs (.xcstrings), plurals, and placeholders - without uploading your source code.
Built for indie developers and small teams who want to ship multilingual releases without the localization tax. No API keys. No accounts. No source-code upload. Just import, translate, and export.
WHY DEVELOPERS CHOOSE STRINGWISE
- AI Localizer for Xcode - Drop in a `.xcstrings` file or Xcode project folder. Translate every string in one click, no copy-paste between tools.
- Smart Context, On-Device - Reads your Swift code locally to understand whether each string is a button, alert, tab, or label. Better translations, zero source-code upload.
- Placeholder-Safe - `%@`, `%d`, `%1$@` and other format specifiers stay valid in every target language. No runtime crashes from broken localizations.
- CLDR Plural Rules - Correctly handles every plural form for languages with up to six categories (Arabic, Russian, Polish, and more). Output works with modern String Catalog plural variants out of the box.
- Device Variants - Supports iPhone, iPad, Mac, and Apple Watch device-specific text variants in your catalog.
- Privacy-First - Source code analysis happens entirely on your Mac. No telemetry, no backend tracking, no `.swift` files leaving your machine.
- Skip Manual XLIFF - No more exporting XLIFF, sending to an agency, waiting a week, then merging conflicts. Translate, review, export, ship.
HOW IT WORKS
1. Drop your `.xcstrings` file or Xcode project folder into StringWise.
2. Select target languages from the 24 supported.
3. Optionally enable Smart Context for better accuracy via on-device code analysis.
4. Click Translate and watch the catalog fill in.
5. Save the updated `.xcstrings` and build in Xcode.
