How it works

One engine, configured for your language and your newsroom.

DeepTranslate (deeptranslate.eu) is an AI translation engine for regional and minority European languages, built into broadcasters' subtitle workflows. Text comes in from your system, the engine translates it with a glossary for each language pair, a QA agent checks every segment, and your editors stay in control. Every correction makes the next programme better.

Frequently asked questions

What is DeepTranslate?

DeepTranslate is an AI translation engine for regional and minority European languages, built into broadcasters' subtitle workflows. It applies a glossary per language pair, checks every segment with a QA agent and keeps editors in control.

Does a human check the output?

Your editors review output whenever it needs a human eye. The QA agent checks every segment first, so editors only see what needs them.

How does it connect to our systems?

Through one API that takes subtitle files, scripts or a caption stream and returns finished subtitles in the format your playout expects. At RTL Lëtzebuerg, integration took days.

Which languages does it support?

Each language has a status in the Language Atlas: Production, Lab or On request.

Who is DeepTranslate for?

Broadcasters, publishers and media groups that publish in regional or minority European languages, or for audiences who speak them. It is a business service built into newsroom workflows, not a consumer translation app.

Is DeepTranslate a localization platform like Smartcat or Lokalise?

No. Localization platforms manage translation projects for software, websites and documents. DeepTranslate is a translation engine built into broadcast subtitle workflows, for regional and minority European languages, with a glossary per language pair and a QA check on every segment.
