## 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

## ModernMT

ModernMT is the machine translation product built by Translated, the language services company behind MyMemory. Its central idea is adaptivity: rather than a single generic model, ModernMT lets each user's project learn from their own corrections, translation memories and glossaries, so the engine's output increasingly matches house style and terminology.

The platform is aimed at professional localization teams rather than casual translation. It combines a web dashboard for managing memories, glossaries and engines with a REST API and official SDKs for Node.js, Python, Go, Java, .NET and PHP, plus plugins for CAT tools including Trados Studio and memoQ. That makes it practical to embed inside an existing translation pipeline instead of replacing it.

Important operational note: Translated is migrating ModernMT to a newer platform called Lara, powered by a domain-specific large language model. According to the company, ModernMT will sunset by the end of 2026; existing API keys and plugins remain functional until December 31, 2026, and new sign-ups on modernmt.com are closed with new users directed to Lara. Anyone evaluating ModernMT today should plan for that migration path.

**Pricing & Plans:** ModernMT has historically offered a free trial alongside paid subscription and pay-as-you-go API plans, with custom enterprise agreements. Current pricing is quoted per project and is being reworked into dedicated Lara plans during the migration, so exact figures should be confirmed with the vendor.

- **Adaptive machine translation:** The engine continuously learns from translator corrections, so quality on your own content improves with use.
- **Translation memory and glossary:** Upload and manage translation memories and glossaries so terminology and past phrasing are respected in output.
- **API and CAT tool plugins:** Integrate the engine into Trados Studio, memoQ or your own stack via a documented REST API and SDKs for Node.js, Python, Go, Java, .NET and PHP.
- **Domain-aware engines:** Context-aware engines recognize the domain of a text and apply the most relevant translation memories automatically.
- **Batch and document workflows:** Process documents and batches through the platform as part of a localization pipeline, with support for 200+ language pairs.

**Strengths:** Output improves over time by learning from your own corrections; Strong professional-tooling story with CAT plugins and SDKs; Supports 200+ language pairs; Backed by Translated, an established language services provider

**Limitations:** Service is scheduled to sunset by the end of 2026; New sign-ups on modernmt.com are closed; new users are redirected to Lara; Document, image and audio translation are not available in ModernMT itself; Advanced adaptation (context, instructions, style guides) only exists on the newer Lara platform
