On-premises document translation for organizations that cannot send data to the cloud.
Faithful formatting, 30+ European languages, and the freedom to run it on any LLM — entirely behind your firewall.
Sovereign Translator is built for regulated European organizations that handle confidential documents and cannot route them through a public cloud service. If a leaked contract, filing, or patient record would be a compliance incident, this is the translator for you.
Runs entirely on-premises and supports fully air-gapped operation. Zero third-party API calls — your documents never leave your firewall, and nothing is used to train external models.
Faithfully preserves complex multi-page tables, nested lists, headers and footers, and font styles in DOCX files. Note: embedded images stay in place, but text inside images is not translated.
Covers 30+ languages with strong European pair coverage — Polish, German, French, Spanish, Italian and more — with glossary and terminology support for consistent results.
Model-agnostic by design. Point the pipeline at any OpenAI-compatible endpoint — Mistral, Llama, or your own specialized regional model — and switch engines as your needs change.
Use the desktop interface for everyday work, or run a headless, interfaceless mode that plugs into pipelines and automation for high-volume, hands-off translation.
GDPR-aligned and built for regulated work, with audit logging hooks, human-review workflows, and documentation support for EU AI Act readiness.
