Get ready to do even more with the DeepL API

What could your product design and developer teams do with the capabilities of the world’s most advanced Language AI? How much extra productivity could your internal systems generate with instant translations and writing suggestions integrated into them? How much smoother and more personalized could your customer experiences become? And how much more value could you create for your teams?

These aren’t just hypothetical questions. They are questions we’ve carefully considered as we’ve expanded the capabilities and options available to developers through the DeepL API. And these are all available to you now!

Plugging the latest DeepL capabilities into our API

The DeepL API gives developers access to our Language AI platform in an accessible format that makes it easy for them to build with — in their preferred programming language and ecosystem. This enables your business to deploy our Language AI models within your own tech stack, in a way that’s fully customizable, adapted to your business and your audience, and that adheres to the strict data privacy and security standards that you get with DeepL.

We have always been committed to helping developers and their businesses to do more with DeepL, which is why we’ve expanded the capabilities of the DeepL API in two game-changing ways:

• We’ve made DeepL’s next-generation language models available through the API, so you get access to the highest levels of accuracy for your translation workflows. Our next-generation language models are preferred by language experts 1.3x more often than Google translate, and 1.7x more often than ChatGPT-4.
• We’ve created DeepL API for Write, so that your developers can integrate Write’s functionality for suggestions to improve written content — in multiple languages — and use it across your platforms and products.

How international businesses drive value with the DeepL API

The DeepL API is already powering innovation and growth for a wide range of international businesses. For instance, translation platform Weglot uses it to help more than 50,000 businesses create multilingual websites. While Alza, the rapidly growing e-commerce business known as the Czech Amazon, relies on it to automatically translate product reviews and listings into multiple European languages, fuelling international growth and saving thousands of Euros in translation costs each month.

With the addition of DeepL API for Write and access to our next-generation language models, our API now enables more businesses to do more with Language AI. For instance: 

• Designing more sophisticated translation workflows that improve expression and clarify meaning in one language, before translating into others. It’s an approach that we know enhances impact and accelerates translation workflows. 
• Building DeepL API for Write into internal communication systems helps all employees to express themselves confidently and consistently, eliminating their time spent second-guessing what they’re typing or worrying about using the right tone or style. It helps collaboration, boosts productivity, and ensures that your internal platforms feel more intuitive to everyone.
• Access to our next-generation language models means your developers and designers can build the most accurate, human-sounding translations into the workflows and systems they create.

Where can DeepL’s API take you?

Imagine equipping your Customer Success teams with bespoke tools that help them express themselves clearly in the preferred language of people who get in touch. How about designing personalized chatbots that deliver multilingual customer service that sounds authentically human? Think of the value of internal systems that can translate, edit and improve entire documents in just a few clicks. And calculate the sales growth you could achieve when ecommerce sites and product listings are instantly translated into the preferred language of customers – especially when data from CSA Research shows that 40% of online shoppers only buy from sites in their own language.  

Imagine all of this built into your own tech stack, as native components of your products, solutions and customer experiences, and fuelling the innovation that drives value for your business. That’s why we created the DeepL API, and why we continue to expand its capabilities. Now, with the addition of DeepL API for Write and our next-generation language models, you can deliver more value than ever before to your teams and your customers.
