SYSTRAN is a machine translation and natural language processing company offering neural (Pure Neural Machine Translation / PNMT) translation across 50+ languages. The SYSTRAN Translate API is a RESTful service (base https://api-translate.systran.net) that translates text, files, and HTML, detects and lists supported languages, and manages translation profiles, user dictionaries, and corpora. The broader SYSTRAN Platform / SYSTRAN.io surface adds NLP operations - morphology, tokenization, segmentation, named entity recognition, and language identification. Requests authenticate with an API key (key query parameter or Authorization header). SYSTRAN sells access as a Developer cloud subscription (14-day / 500,000-character free trial) plus Professional SaaS and Enterprise cloud/on-premise plans, billed per character.
