What makes a good Word document translation
SECURITY
Your Word documents never leave Swiss infrastructure
Word files frequently contain more than visible text – track changes, comments, author metadata and revision history are all embedded. Unlike translation features that route data through US-based servers, Supertext processes your documents exclusively on Swiss servers. Nothing is retained after translation.
