What Is an AI Translator with Contextual Memory?
An AI translator with contextual memory is an advanced platform that goes beyond simple sentence-by-sentence translation. It uses features like translation memory (TM), adaptive machine translation, glossaries, and Retrieval-Augmented Generation (RAG) to understand and remember the context of your entire document or conversation. This 'memory' allows the AI to maintain consistency with terminology, resolve ambiguities, and learn your specific style over time, resulting in far more accurate and natural-sounding translations for professional and enterprise applications.
