AI Localization with Custom.MT plugin brings the latest neural machine translation (MT) and GenAI models (LLMs) to Trados Studio.

Key Features

1. AI Workflows – build workflow templates that combine NMT and LLMs and generate automated translations based on style guide, formality, and units of measurement settings.
2. Automated Post-Editing (APE): improve NMT output using LLMs with custom prompts.
3. Custom Prompts: create, edit, and reuse your own GenAI prompts to stylize the text. You can define any instruction set to fit your workflow.
4. Best Engine: evaluate MT or LLM models based on closeness to your translation memory (TM) using BLEU scores and Word-Error Rate metrics.
5. AI Glossaries: add your terminology assets and let AI automatically inflect and adapt terms to the correct form, gender, and number in context.
6. Centralized Access: no need to purchase API keys or create separate accounts — all models and engines are available through your Custom.MT Console.
7. Data Security: all data is processed within the EU (AWS Frankfurt, ISO 27001 / SOC 2 compliant), with no data retained outside your project session. Custom.MT has opt-out and data protection agreements with OpenAI and Anthropic Claude.
