## 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

## Custom.MT

Custom.MT sits at the intersection of machine translation engineering and generative AI localization. The platform gives localization teams a single console for managing translation engines, whether those are off-the-shelf providers or models trained specifically on a client's terminology and style. Because the console connects to the CAT and TMS tools translators already use, MT becomes part of the existing workflow instead of a separate step.

Beyond the software, Custom.MT operates as a language AI partner. Teams can commission evaluation projects to benchmark engines by language, domain and linguist, run an annual translation memory cleanup, or deploy machine translation on their own hardware when confidential content must not leave the building. Automatic post-editing, language data anonymization and in-domain dataset acquisition round out the service catalog.

The audience is localization managers, language service providers and product teams that treat translation quality as a measurable engineering problem. Companies typically begin with a free trial of the console or a discovery call, then scale into fine-tuned or private models as volumes and quality requirements grow.

**Pricing & Plans:** Custom.MT offers a free trial of the AI translation console and a documented API; full pricing for platform access and services is quote-based, with a discovery call recommended for enterprise MT, fine-tuning and on-premise projects.

- **Central engine management:** Manage stock engines and your own custom models from one console, then push them into the linguistic tools your team already works in.
- **MT and LLM engine evaluation:** Compare DeepL, Google, GPT-class and custom models with BLEU, WER and COMET scores plus sample segments to find the best engine per language pair.
- **Model fine-tuning:** Fine-tune translation models on your terminology, style guides and past translations to cut edit distance and post-editing cost.
- **CAT and TMS connectors:** Plugins and extensions for Trados, Smartling, memoQ, XTM Cloud, Smartcat and Shopware keep MT inside existing localization workflows.
- **TMX cleaning and data services:** Clean up stale translation memories, remove personal data and source in-domain training sets for medical, legal, patent and eCommerce content.

**Strengths:** Unusually broad service catalog, from MT evaluation and fine-tuning to on-premise deployment and TMX cleaning; Engine comparison with standard metrics makes quality decisions defensible rather than anecdotal; Plugins for the major CAT and TMS tools mean minimal disruption to existing localization pipelines; Combines software with human expertise, useful for teams without in-house MT engineers

**Limitations:** Enterprise-grade services and on-premise deployments require a discovery call rather than instant self-serve setup; The strongest value (fine-tuning, evaluation, data acquisition) requires localization engineering knowledge to exploit fully; Pricing is not fully transparent on the marketing site for larger service engagements
