Our focus

German localization as a competitive advantage

German-language training and test data is a gap for many AI systems. We fill it — with native-speaker quality.

  • 1
    Native-speaker qualityGerman as a first language — natural phrasing instead of machine-translated wording.
  • 2
    Context & cultureUnderstanding of regional nuance, formal address (Sie/du) and technical language.
  • 3
    Accuracy over volumeReliable, fully vetted data instead of fast mass-produced batches.

Examples of German localization

Language models, chatbots, translation and text systems that need natural German — from colloquial to technical register.

„Der Kabelbaum ist der Flaschenhals in der Fertigungsstraße." — understandable to specialists, but a language model needs context first. We annotate such sentences with meaning, topic and intent.
