## 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

## 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
