Direct answer
What is SYSTRAN?
SYSTRAN provides neural machine translation software available via self-serve cloud subscriptions, developer APIs, dedicated private cloud, and fully on-premise servers for security-conscious enterprises.
Operating in machine translation since 1968 and now part of ChapsVision, SYSTRAN delivers professional-grade automated translation across 55 languages. The platform focuses on security, terminology control, and flexible deployment models to serve regulated industries, government organizations, and multinational corporations. For individual professionals and small teams, SYSTRAN translate PRO offers document, text, and webpage translation. It handles over 30 file formats—including Microsoft Office files, PDFs, XML, JSON, and IDML—while preserving document layouts. Users can upload custom glossaries, apply normalization dictionaries, and leverage industry-specific neural translation models. French speakers also benefit from direct translation models that do not pivot through English. For large enterprises with stringent data privacy rules, SYSTRAN offers dedicated Private Cloud and on-premise translate Server installations. The on-premise server translates up to 6,000 words per second with unlimited translation volume and user access points. Translators can also use Model Studio to train custom neural translation engines on internal translation memories and parallel corpora.
Unlike consumer-oriented web translators, SYSTRAN provides true on-premise and dedicated private cloud deployments alongside ISO 27001 compliance, strict European data sovereignty, and custom model training via Model Studio.

Editorial assessment
Pros and limitations
Where it is strong
- Complete deployment flexibility including customer-hosted on-premise servers and private clouds

- Direct French translation engines that bypass English pivoting for higher accuracy
Where to be careful
- Entry-level Pro tiers cap translation volume (1M to 3M characters per month)
