## 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

## String Catalog

String Catalog keeps localization inside source control instead of spreading it across spreadsheets and side tools. You connect the repository you already ship from, choose the branch you release from, and String Catalog proposes translation updates as clean diffs that your team reviews and merges like any other change. Native formats stay native: .xcstrings files for Apple platforms and Android strings.xml both round-trip without hand cleanup or one-off scripts.

The product deliberately covers more than raw strings. App Store and Google Play release notes and store listing copy can be prepared in the same workspace, with platform-specific field limits, locale codes, and exportable output that growth teams can ship directly. Tone guidance, protected brand terms, and glossaries travel with every new language so the result sounds like your app rather than a generic machine translation.

Quality control is built into the loop. Reviewers get secure no-login links, suggested fixes appear in review queues, and low-confidence output can be retried before release week. Pricing is deliberately flat across languages: every plan covers up to 40 languages, so cost depends on string volume and workflow needs rather than how many markets you enter.

**Pricing & Plans:** Paid subscription with a monthly or annual option (annual saves about 20%) and one free language to trial. Published plans are Hobby at $15/month, Pro at $45/month, and Business at $75/month, differing mainly by base string-key limits and review features. All plans include up to 40 languages and no per-language charge. Check the site's cost calculator for current figures.

- **Git-native, reviewable workflow:** Connect GitHub, GitLab, or Bitbucket and receive localization updates as pull requests and clean diffs on the branch you release from, so your repository stays the single source of truth.
- **Native format support:** Round-trip .xcstrings for Apple platforms and Android strings.xml without spreadsheet export, broken builds, or custom scripts.
- **Release notes and store metadata:** Translate App Store and Google Play release notes and store listing copy in the same product, with platform-specific field limits and locale handling.
- **Brand voice and glossary controls:** Protect brand terms, add tone guidance, and reuse glossaries so each new locale keeps the product voice users already know.
- **Human review with secure links:** Share no-login review links, inspect suggested fixes in review queues, and bulk-accept edits when a translation needs more than an automatic pass.

**Strengths:** Stays inside the Git workflow teams already trust, with pull requests and clean diffs instead of silent content mutation; Flat pricing across up to 40 languages removes per-locale cost math and makes adding markets predictable; Covers strings, release notes, and store metadata in one product instead of three separate tools; Human review tooling, protected terms, and tone guidance are included rather than bolted on

**Limitations:** Built primarily around iOS and Android app workflows, so web or backend-only projects may find it a tight fit; Review quality features such as shared review links and accuracy monitoring are limited to higher-priced Pro and Business plans; Base string-key ceilings on each tier mean very large apps need to size plans carefully or move up a level
