Advanced AI technology meets unbeatable translation accuracy

Our innovative and award-winning breakthroughs continue to set industry standards, taking us closer to our vision: creating a world without language barriers.

More than 1 billion choose DeepL for our exceptional translation quality, powered by our groundbreaking artificial intelligence technology.

The world's best machine translation

DeepL’s neural networks are able to capture even the slightest nuances and reproduce them in translation unlike any other service. To assess the quality of our machine translation models, we regularly conduct blind tests. In blind tests, professional translators select the most accurate translation without knowing which company produced it. DeepL outperforms competition by a factor of 3:1.

Proven to outperform the competition

“Tech giants Google, Microsoft and Facebook are all applying the lessons of machine learning to translation, but a small company called DeepL has outdone them all and raised the bar for the field.

Its translation tool is just as quick as the outsized competition, but more accurate and nuanced than any we’ve tried.”

Since DeepL’s initial launch in 2017, we have been developing a completely new generation of neural networks (NN). Using a novel NN design, DeepL networks learn to grasp the subtle meanings of sentences and translate them to a target language in an unprecedented way. 
This has led to a world-renowned machine translation quality that surpasses 
all major tech companies.

DeepL not only keeps up with world-leading deep learning companies but 
continues to set new standards with its advancements in neural network 
mathematics and methodology. In 2020 and 2021, we launched new models that can more accurately convey the meaning of translated sentences, even overcoming the challenge of industry-specific professional jargon with great success.

At DeepL, we are just getting started. We will continue to use our expertise in artificial intelligence and neural networks to create technologies that make communication faster, better, and easier.
