Language Weaver

What it does

Language Weaver is an enterprise machine translation platform from RWS for businesses that need to process multilingual content quickly. Developers send text or documents through its APIs and receive neural machine translation output. It also covers related tasks including language detection, optical character recognition, document summarisation and quality estimation.

Teams typically connect their own applications to the Language Weaver APIs, so translation runs inside an existing system rather than a separate interface. The cloud version is reached through a portal account with API credentials, while a scalable on-premise application serves organisations that need to host the software themselves. Each deployment type exposes its own set of API endpoints.

Language Weaver suits developers and businesses that want secure, real-time translation built into their own products or workflows. Cloud access requires signing up to a plan that supports API integration, and the on-premise Language Weaver Edge API is documented separately. Pricing and plan details are not published on the developer pages, so cost should be confirmed with RWS before committing.
