Overview

SYSTRAN translates across 55 languages and more than 30 file formats including Office documents, PDF, XML and IDML, with a browser extension, speech-to-text translation, drag-and-drop document handling and Neural Fuzzy Adaptation for existing translation memories. Cloud products run as Translate PRO, Enterprise and API; on-premise runs as Translate Server, Private Cloud and Model Studio for training custom models.

The on-premise line is why this survives against free general-purpose translation. A bank, a defence contractor or a hospital cannot send documents to a translation API at all, regardless of quality, and that constraint has nothing to do with how good the model is. Running the engine inside the customer’s own infrastructure, and letting them train it on their own terminology, is a category of product most competitors do not offer.

SYSTRAN by ChapsVision claims over 50 years in translation technology, 6,000 words translated per second, and more than 1,000 corporate customers including Societe Generale, Swiss Post and Lufthansa. Three pricing tiers exist – Professional, Enterprise and Developer – with no figures published and quotes on request. Six product lines makes choosing genuinely confusing, Neural Fuzzy Adaptation only pays off if you already have a translation memory, and on-premise deployment is a procurement exercise before it is a purchase.
