StringWise Localizer for Xcode

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.
