Whether you're a startup expanding into Europe, a manufacturer coordinating with suppliers in Japan, or a game studio engaging players worldwide, language barriers slow down every aspect of growth. Traditional translation solutions often force you to choose between speed and quality—until DeepL came along.

Text Translation gives you instant, accurate translations across 30+ languages. Whether you're drafting emails, preparing documents, or chatting with international colleagues, DeepL delivers translations that need far fewer edits than competing tools—typically 2-3x less revision work. The system leverages specialized terminology databases and grammar rules to ensure accuracy in context.

Document Translation preserves your original formatting while translating PDF, Word, PowerPoint, and Excel files.

Japanese company JAE achieved 86% efficiency improvement in document translation workflows using this feature.

Glossary Management lets you create and maintain personalized terminology databases. This ensures consistent translations of brand names, industry-specific terms, and technical vocabulary across all your content. Deutsche Bahn manages over 30,000 glossary entries to maintain translation consistency across 16 languages.

DeepL Voice enables real-time speech translation for meetings and conversations. Integrated with Zoom and Microsoft Teams, it provides live captions and translation during international calls—making multilingual collaboration feel natural. Brioche Pasquier uses this feature to create inclusive communication across their international teams.

DeepL Write functions as your AI writing assistant, checking grammar, optimizing style, and refining tone. It supports multiple writing styles, helping you craft polished business emails, marketing copy, and cross-language content that resonates with your audience.

Who Uses DeepL

DeepL serves organizations across virtually every industry. Here's how different teams put the platform to work:

Enterprises pursuing global expansion use DeepL to accelerate market entry. When entering new countries, you need high-quality translations of websites, marketing materials, legal documents, and product descriptions—fast. DeepL's speed combined with terminology management ensures your brand voice remains consistent across markets. JAE's 86% efficiency improvement demonstrates how dramatically DeepL can accelerate localization timelines.

Legal and professional services rely on DeepL for documents where precision matters. Law firms and consulting companies handle contracts, filings, and client communications where terminology accuracy is non-negotiable. Nagashima Ohno & Tsunematsu, one of Japan's top law firms, uses DeepL to shorten translation time and simplify workflows while maintaining the accuracy their clients expect.

Customer support teams leverage DeepL Voice and document translation to respond to global customers efficiently. When Paysend implemented DeepL, they achieved a 10% improvement in customer satisfaction within just one quarter—because their support team could communicate clearly in customers' native languages.

Multinational corporations depend on DeepL to eliminate language barriers in internal communications. Deutsche Bahn coordinates operations across 16 languages using approximately 30,000 glossary entries to ensure every team member receives consistent, accurate information regardless of location.

Life sciences and healthcare organizations require both accuracy and security when handling regulated documentation. DeepL's enterprise-grade security certifications (SOC 2 Type II, ISO 27001, GDPR compliance) combined with precise translation and terminology management help these organizations scale their multilingual capabilities while meeting strict regulatory requirements.

Manufacturing and engineering companies handle extensive technical documentation requiring precise terminology. JAE's success with DeepL—achieving 86% efficiency gains—illustrates how manufacturing teams benefit from accurate technical translations across global supply chains.

Gaming and entertainment companies deliver localized experiences to players worldwide. SQUARE ENIX and thatgamecompany integrate DeepL to enable seamless communication between global offices and international player communities.

Retail and e-commerce businesses translate product descriptions, customer reviews, and marketing content at scale. Companies like Alza.cz use DeepL to provide natural-sounding translations in languages like Czech, creating authentic shopping experiences for local customers.

Technical Architecture and Security

DeepL's technology foundation combines cutting-edge AI research with enterprise-grade infrastructure designed for security and reliability.

Next-generation language AI models form the core of DeepL's offering. Unlike competitors that rely primarily on web-scraped data, DeepL trains its models using proprietary datasets enhanced by professional linguists. This human expertise embedded in the training process is why DeepL consistently outperforms other AI translation systems in quality assessments. The company was the first in Europe to deploy NVIDIA DGX SuperPOD systems (including DGX GB200), giving them computational infrastructure that rivals major tech companies.

The supercomputer clusters powering DeepL run on renewable energy, reflecting the company's commitment to sustainable AI development. This infrastructure supports translation capabilities across more than 100 languages, with particularly strong coverage in 30+ major languages used in global business.

Security certifications demonstrate DeepL's commitment to protecting enterprise data. The platform holds SOC 2 Type II certification (covering security, availability, and confidentiality), ISO 27001 certification, and full GDPR compliance. Regular penetration testing—both internal and external—ensures vulnerabilities are identified and addressed promptly.

Data protection measures go beyond certifications. DeepL never stores or uses customer text for model training unless you explicitly consent. All data transmissions use TLS encryption. Enterprise features include SSO support (both OIDC and SAML protocols), multi-factor authentication, and role-based access controls. For organizations requiring additional control, DeepL offers Bring Your Own Key (BYOK), allowing you to manage your own encryption keys.

Availability guarantees meet enterprise requirements. Business plans provide 99.0% uptime SLA, while Enterprise customers receive 99.9% availability with dedicated support resources. Comprehensive audit logs enable compliance reporting and security monitoring.
