Supertext – The adaptive, sovereign AI translator with human experts built in

Businesses worldwide spend USD 31.7 bn on translation every year, whether that's fully AI-driven or reviewed by professionals. While AI tools keep getting better, a fundamental issue remains: no non-human system will ever be able to certify correctness. Professional translators, on the other hand, are often simply too slow and expensive. The result for most businesses: outsourced processes with 17 different vendors, uncertain data protection, manual corrections and no continuous adaptation of the underlying language models to their use case.

Launched in February 2025 at supertext.com, our AI translator is based on enterprise-grade, sovereign LLMs hosted on our Swiss servers or on infrastructure of the customer's choice. We seamlessly integrate more than 3,000 experienced human linguists: our Verification feature lets users have important translations reviewed by professionals within 8 minutes while tailoring their custom translation model to their use case in the process. This makes the system more precise every day, reducing the need for professional oversight over time.

Our enterprise clients see an up to 90% increase in ready-to-publish AI output, 93% faster turnaround for professionally verified translations and a 64% reduction in overall translation spend. These gains aren't theoretical, but are in production today at 1,500 businesses including Swiss Life, AXA and SBB – even for Swiss German and Romansh.
