|---|---|---|
| Japanese-English specialization | Japanese-English translation | DeepL handles Japanese-English well but MiraiTranslate may have deeper domain-specific training for technical Japanese |

| API integration | DeepL API | DeepL API supports similar functionality with different endpoints and parameters |
| Industry-specific models | Glossaries and context settings | DeepL uses glossaries rather than separate models; may require more manual configuration |

Data Transfer Guide
Export from MiraiTranslate: Access your dashboard and export terminology databases, translation memories, and glossaries in CSV, TMX, or XLIFF formats. Download historical translations and project files. For API data, export usage logs. Import to DeepL: Convert files to DeepL-compatible formats—CSV for glossaries (term, definition, part of speech). In DeepL Pro, navigate to Glossary Management and upload files. Translation memories in TMX format can be used as reference but require manual recreation in DeepL's system. Document files must be re-uploaded directly to DeepL's translation interface as there's no direct import for translated documents.
