Customization Hub: Your AI control layer for brand voice and compliance

Key Takeaways

• DeepL Customization Hub is an AI control layer that centralizes brand voice and compliance decisions for every translation.
• Translation memories, style rules, glossaries, and style profiles capture expert choices and apply them automatically across teams and languages.
• These features reduce repetitive post-editing, cut localization time and costs, and keep content accurate, compliant, and on-brand at scale.
• Customization Hub acts as a central rulebook for DeepL's Language AI suite, keeping every output aligned with your brand.

In terms of creating multilingual content at scale, there’s a big difference between an accurate translation and a “right” translation. 

The right translation doesn’t just communicate the meaning of words. It communicates the essence of your brand and conforms to your legal, regulatory, and other business requirements. How? It understands the specific language choices you make.

Here are the types of language choices that make that difference:

• The types of phrases that you would or wouldn’t use
• The tone and style of sentences that you construct
• Your house style on everything from dates and times to abbreviations and contractions
• Terminology specific to your brand and your products, plus terminology specific to the ideas that your business develops and communicates

The challenge is that these choices are often embedded in many different places and rarely in one central source of truth.

The problem: scattered language choices

Your language choices are in scattered style guide PDFs hidden in different systems. They exist in the minds of your editors and localization leads. They’re with the people who instinctively know what your brand sounds like and how that evolves over time. 

It’s difficult and time-consuming to research and apply these various points of style manually. That’s why correcting translations to align with static style guides and language nuances takes up so much time and cost in localization workflows.

And that’s why we created the DeepL Customization Hub.

The solution: DeepL Customization Hub

What is DeepL Customization Hub? It’s an AI control layer for translations we introduced at DeepL Dialogues 2025.

It takes all the decisions, preferences, and styles that define your brand voice and applies them to every translation. Every team in every language shares the same rules, so content stays consistent, compliant, and on-brand.

The Customization Hub brings together four powerful features in a single source of truth for style policies and preferences.

Your translations sound like you, engage like you, and comply with your guidelines while dramatically reducing time and localization costs.

Let’s look at those four powerful DeepL Customization Hub features.

1. Translation memories: reduce repetitive post-editing

Translation memories mean you never spend time on repetitive post-editing because your approved translations automatically guide new ones.

You can now create and import your translation memories into DeepL. This gives your DeepL translations the same contextual understanding as your in-house language experts.

Every past translation you’ve approved and stored in your translation memory can contribute to more accurate, on-brand future translations. You receive translations that are right the first time, making localization much faster. 

This is possible because DeepL's unique approach to AI transforms partial “fuzzy” matches into precisely adjusted smart matches that fit grammar and context. As a result, your translation memories can now apply previously approved translations everywhere they’re relevant. 

This ability also eliminates the vast majority of repetitive post-editing work.

2. Style rules: capture and codify brand voice

Style rules are the most powerful way to get your brand voice heard in every translation.

Say goodbye to scattered and siloed style guides. Say hello to DeepL style rules: one source of truth that ensures every translation hits your targets:

• Stays on-brand 
• Remains on message 
• Conforms to all your style and formatting guidelines

With DeepL style rules, it’s easy to capture and codify all the elements of your brand and how it communicates. 

You can create style rules in three ways. 

First, you can choose from suggested rules for areas like grammar, punctuation, time, and date to define the combinations that reflect your house style. 

Second, you can write your own style rules in straightforward, natural language. You specify any preference you like on tone, style, formality level, preferred phrases, and phrases to avoid.

Lastly, DeepL can generate style rules from your existing content. When you upload a piece of text that feels right for your brand, our AI extracts the points of style that help replicate it for future translations. 

This style rule generation is a feature that makes it easy to define what makes your brand unique. Furthermore, it helps your style evolve as your brand voice evolves.

3. Glossaries: consistent, context-aware terminology

Glossaries give you consistency and accuracy across all your translations, so key terms always land naturally and with impact.

Use DeepL glossaries to set how the AI translates your important brand, product. and industry terminology. The Language AI adapts to context so that technical terms and key brand phrases sound fluent and on-brand every time.

DeepL provides a range of options to make it quick and easy to create the glossaries your business needs. You have several easy paths: 

• Import your existing glossaries.
• Generate suggested glossaries based on your own previous translations.
• Choose from predefined lists of translation options for key terms in areas like marketing and legal.

Regardless of industry, DeepL glossaries pinpoint nuances in your field.

4. Style profiles: presets for teams and use cases

Style profiles combine all your customization preferences and make them available for each team with the flip of a switch.

Create a style profile for a specific team or project. Then, assign to that profile all the glossaries, style rules, and translation memories that you want your team to use in their translations. 

It might be that you want your legal contracts to use different terminology to your customer support or product teams. You might want a marketing campaign to adopt a different tone to internal communications. 

Style profiles adjust your Customization Hub preferences to each use case. That means you give employees the exactly right tools for their translation tasks.
