Translate using glossary

See how to talk to your AI agent using DeepL.

Translate 'Welcome to our platform. We look forward to working with you.' into German (formal) and Brazilian Portuguese (informal).

German (formal): 'Willkommen auf unserer Plattform. Wir freuen uns auf die Zusammenarbeit mit Ihnen.' Brazilian Portuguese (informal): 'Bem-vindo à nossa plataforma. Estamos ansiosos para trabalhar com você.' The formal version uses 'Ihnen' (Sie-form) while the informal Portuguese uses 'você' instead of 'o senhor'. Would you like to create a glossary for consistent terminology or translate more content?

Create a glossary for EN→FR with our brand terms and then translate a marketing paragraph using it.

Glossary created! ID: gl_8a4f2c, Name: 'Brand Terms EN-FR', Source: EN, Target: FR, Entries: 5 term pairs. Terms mapped: 'Dashboard' → 'Tableau de Bord', 'Workspace' → 'Espace de Travail', 'Insights' → 'Analyses', 'Onboarding' → 'Intégration', 'Workflow' → 'Flux de Travail'. Now translating with glossary... Result: 'Découvrez notre nouveau Tableau de Bord avec des Analyses en temps réel. L'Intégration est simplifiée grâce à notre Flux de Travail guidé dans votre Espace de Travail.' All 5 glossary terms were applied consistently.
