Description
The AI Localization with Custom.MT plugin brings the latest neural machine translation (MT) and GenAI models (LLMs) to Trados Studio.
Key Features
- AI Workflows – Build workflow templates that combine NMT and LLMs, and generate automated translations based on style guide, formality, and units of measurement settings.
- Automated Post-Editing (APE) – Improve NMT output using LLMs with custom prompts.
- Custom Prompts – Create, edit, and reuse your own GenAI prompts to stylize text. Define any instruction set to fit your workflow.
- Best Engine – Evaluate MT or LLM models based on closeness to your translation memory (TM) using BLEU scores and Word-Error Rate metrics.
- AI Glossaries – Add your terminology assets and let AI automatically inflect and adapt terms to the correct form, gender, and number in context.
- Centralized Access – No need to purchase API keys or create separate accounts — all models and engines are available through your Custom.MT Console.
- 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.
