Manage and Connect Models
Manage your stock and custom translation models and connect them to linguistic tools and content systems via the Custom.MT Console.
Engine Evaluation & Comparison
Compare DeepL, Google, GPT‑4, custom and other models using the Best Engine tool with BLEU, WER scores, example segments, and engine rankings to select the right model.
Tag Processing
Tag processing routines let you either preserve tags in software strings during AI translation or clean them out to fit your localization workflow.
Model Training & Fine-Tuning
Train and fine-tune models to improve accuracy with terminology and style, reducing edit distance and achieving localization savings.
Machine Translation Evaluation
Measure model performance by language, domain and linguist with automated and human evaluations using metrics such as BLEU, WER, and COMET.
On-Premise Machine Translation
Deploy MT on your hardware to process confidential content without sending data to the cloud.
Translation Memory (TMX) Cleaning
Perform annual TMX cleanups to keep translation memories useful and to prepare data for model training.
Automatic Post-Editing (APE)
Replace manual review with automatic machine translation post-editing to cut linguistic audit costs (the site notes potential savings of up to 70%).
Language Data Acquisition
Search for and acquire in-domain training datasets from public sources and marketplaces (medical, legal, patent, eCommerce data).
Open-Source Machine Translation
Build custom MT models from open-source data and modern neural network toolkits.
Language Data Anonymization
Automatically remove personal information (names, telephone numbers, social security numbers) while keeping language data usable for training.
Plugins & Extensions
Plugins and extensions for Trados, Smartling, memoQ, Shopware, XTM Cloud, and Smartcat to integrate MT into existing localization toolchains.
API Access
API is listed among products and developer resources to integrate the platform with other systems.
