Sovereign Translator

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.

Translates DOCX, PPTX, XLSX, JSON and Markdown; PDF support is on the roadmap.

A hosted SaaS option and a 14-day public-cloud trial are available when cloud processing is acceptable.

Sovereign translate's effective interface

Who is it for?

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. A hosted SaaS option is available for evaluation and for cases where cloud processing is acceptable.

  • Government agencies and offices — translate classified and citizen-facing documents without external data transfer
  • Banks and financial institutions — keep filings, contracts, and KYC/AML records inside your own infrastructure
  • Courts and legal systems — translate case files and contracts under strict confidentiality
  • Health organizations — process medical records and research while protecting patient data
  • Educational institutions — universities and schools translating research, administrative, and student materials
  • Research organizations — work across languages on unpublished and sensitive findings
  • Private companies — protect commercially sensitive documents and intellectual property
  • Public libraries — widen access to collections without depending on external services

Why is it better?

Sovereign by design

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.

Formatting fidelity

Faithfully preserves complex multi-page tables, nested lists, headers and footers, and font styles in DOCX, PPTX and XLSX files. JSON and Markdown structure is preserved where supported. Note: embedded images stay in place, but text inside images is not translated.

Built for European languages

Covers 30+ languages with strong European pair coverage — Polish, German, French, Spanish, Italian and more — with glossary and terminology support for consistent results.

Your LLM, your stack

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.

Flexible deployment

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. A hosted SaaS option is available when cloud processing is acceptable.

Enterprise-ready

GDPR-aligned and built for regulated work, with audit logging hooks, human-review workflows, and documentation support for EU AI Act readiness.

Deployment & free trial

On-premises deployment is the primary way to run Sovereign Translator. A hosted SaaS option is available when cloud processing is acceptable.

On-premises / private cloud
Install Sovereign Translator in your own infrastructure. Air-gapped operation is available, so documents stay behind your firewall.
Hosted SaaS
Also available as an Enelpol-hosted subscription, with web and API access. Documents in this mode are processed in the cloud.
14-day free trial
Request a free 14-day trial in a public-cloud environment and evaluate the product on your own documents through temporary SaaS or API access.

The trial processes documents in a public cloud. Do not use it for documents that cannot leave your infrastructure — talk to us about an on-premises deployment instead. Data processing terms are provided with trial access. Request the data processing terms.

More Information

Supported formats: .docx, .pptx, .xlsx, .json and .md. PDF support is coming soon.

For high-stakes content, we recommend keeping a human reviewer in the loop — Sovereign Translator is built to support that workflow.

The 14-day free trial runs in a public cloud. Production can be deployed on-premises or as SaaS.
