What’s more transformative than an AI video production studio that can turn any script you type into video content in minutes? How about this: an AI video production studio that can show virtual presenters delivering that message fluently in more than 100 languages

That’s what’s now possible, thanks to a groundbreaking partnership between AI video generator Synthesia and DeepL.

The partnership brings together two Europe-founded unicorn businesses that are pioneering AI innovations to transform how people and businesses communicate. Both DeepL and Synthesia launched in 2017, DeepL in Cologne and Synthesia in London. 

Both have developed specialized AI models that enable people to express themselves authentically and naturally while eliminating barriers and reducing costs. By partnering, we can multiply the positive impact of both DeepL’s Language AI and Synthesia’s groundbreaking virtual avatars. 

We’re enabling an entirely new application of Language AI and putting DeepL at the heart of how businesses create video content.

DeepL and Synthesia: a shared mission to eliminate language barriers

More than 65,000 companies use Synthesia’s AI video platform: Heineken, Reuters, Zoom, and Dupont among them. Applications include sales, marketing, internal communications, customer support, and training. 

When users upload a script, Synthesia creates a video with a lifelike avatar delivering it and captures the precise mood, tone, and message the user requires. 

Enterprise customers can even upload smartphone or webcam video of themselves to create their own custom avatar. It’s a “digital twin” that delivers their ideas and messages in their voice, with their expressions, with consistently top-quality performance.

For shared customers of DeepL and Synthesia, it’s like gaining fluency overnight without sacrificing nuance, tone, or professional polish.

“Synthesia’s AI video capabilities and DeepL’s Language AI are a natural fit, and the joint solution is having a huge impact for our customers,” said Brian Jambor, head of Partnerships, Synthesia
