Custom.MT

Machine translation and GenAI localization for enterprise language teams

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.

Strengths & Pros

+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
