## Auto Localize

Auto Localize is a localization workbench built specifically for Apple and cross-platform app developers. Instead of copying strings into a spreadsheet or a web translation service, you point the app at a project folder and it discovers every localizable file — Xcode String Catalogs (.xcstrings), XLIFF 1.2/2.0, .xcloc, .strings, .stringsdict, Interface Builder strings, Android strings.xml, Flutter ARB, Java .properties, .NET .resx and JSON language files. Unity and Articulate Rise projects are handled through XLIFF.

Translation is handled by the model you choose. Apple Intelligence works on-device for free, or you can plug in your own OpenAI, Google Gemini, LM Studio, Ollama, or any OpenAI-compatible endpoint. There is no Auto Localize account and no vendor server: your strings go only to the provider you pick, and API keys stay in the Mac keychain. The app understands plural rules per language, protects placeholders and markup, respects a glossary and tone-of-voice description, and reuses a translation memory so already-reviewed text is never re-sent.

Beyond source strings, Auto Localize can connect to App Store Connect with your own API key to translate the app name, subtitle, description, promotional text, keywords, in-app purchases and events, and it includes a Screenshot Studio for designing and exporting localized App Store screenshots. It is distributed by MOZKAN as a paid Pro app with a free tier for scanning and manual editing.

**Pricing & Plans:** Free to try: scanning all supported formats, manual editing, glossary, translation memory and backups, plus a sample project. A Pro subscription (monthly or yearly) unlocks AI localization with any provider, publishing to App Store Connect, and screenshot exports/uploads. Subscriptions renew automatically until cancelled in App Store settings.

- **Multi-format project scanning:** Detects and rewrites .xcstrings, XLIFF 1.2/2.0, .xcloc, .strings, .stringsdict, Interface Builder strings, Android strings.xml, Flutter ARB, Java .properties, .NET .resx and JSON files, with Unity and Articulate Rise via XLIFF.
- **Bring your own AI model:** Translate with on-device Apple Intelligence for free, or your own OpenAI, Gemini, LM Studio, Ollama or OpenAI-compatible key. No account and no vendor server hold your strings.
- **Plural- and placeholder-aware translation:** Fills every language's plural forms, swaps out %@, %1$d, {{name}} and HTML tags as protected markers, and verifies them on the way back.
- **Glossary, tone and translation memory:** Enforce fixed terms and a brand voice, and automatically reuse text you already translated so it is never sent to a model twice.
- **App Store Connect and Screenshot Studio:** Localize your App Store name, subtitle, description, keywords, in-app purchases and events, and design, translate and export localized screenshots in bulk.

**Strengths:** Native Mac experience with no vendor account or server in the middle; Handles the exact file formats and ordering Xcode and other toolchains write; Choice of translation backend, including fully offline local models; Built-in glossary, translation memory and App Store Connect publishing

**Limitations:** Requires macOS 14 or later, with Apple Intelligence features needing macOS 26; AI localization and App Store/App Store screenshot features are behind the paid Pro plan; Focused on mobile/desktop app projects rather than general document translation

## Xpolyglot

Xpolyglot is a desktop utility built specifically for the Xcode localization workflow. Instead of exporting spreadsheets or pasting strings into a web translator, developers import their Xcode project directly into the app, where all localization projects are tracked in one dashboard. Xpolyglot then uses AI (powered by the user's own OpenAI API key) to translate the .xcstrings string catalog into every target language.

The app's standout efficiency feature is delta updates: rather than re-translating the whole catalog, Xpolyglot detects which strings have changed since the last run and translates only those. That keeps both time and OpenAI API costs low, which the app illustrates with an in-app savings calculator that compares its cost against traditional per-word human translation.

Xpolyglot goes beyond code strings to the App Store. It manages App Store Connect descriptions and keywords across all supported languages, checking them for length and relevance so the app remains discoverable in each market. It also handles versioning, translating the 'What's new' release notes so users are kept informed in their native language. Xpolyglot is notarized by Apple and made by FiveSheep, a small software company based in Estonia.

**Pricing & Plans:** One-time purchase of USD 9.99 for macOS, including lifetime free updates. A separate OpenAI API key is required and its usage is billed by OpenAI; a medium project of 300 keys into 5 languages is estimated at roughly USD 1.11 in API cost.

- **One-click Xcode import:** Import Xcode projects in a few clicks and keep every localization project organised in one place.
- **AI string catalog localization:** Translate the .xcstrings string catalog using your own OpenAI API key for a fraction of professional translation cost.
- **Delta updates:** Detect changed strings and translate only what needs updating, saving both time and API spend.
- **App Store metadata sync:** Keep App Store Connect descriptions and keywords length-checked and relevant in every target language.
- **Version and release notes:** Create new versions and translate the 'What's new' section so users stay informed in their own language.

**Strengths:** Very low one-time price of USD 9.99 with lifetime updates; Purpose-built for Xcode and .xcstrings catalogs, not a generic translator; Delta updates only re-translate changed strings, cutting API cost; Also manages App Store Connect descriptions, keywords and release notes

**Limitations:** Requires you to supply and pay for your own OpenAI API key separately; macOS-only — no Windows, Linux or web version; Translation quality depends on your chosen OpenAI model and prompt; No built-in team seats or cloud sync; it is a desktop app
