What does Supertext do?
Supertext is a translation platform that combines AI with human expertise. You paste text or upload a file, and its AI provides an instant translation. What sets it apart is the option to have that translation reviewed by one of over 3,000 professional linguists in a matter of minutes, not days. This hybrid approach aims for the speed of AI with the reliability of a human check when you need it.
The tool is built for business use, with a strong emphasis on security and customization. All data processing and hosting happens in Switzerland, ensuring compliance with strict European data laws. Its AI isn't static; it can be tailored to your company's specific terminology and style by learning from your past translation projects and glossaries. It also integrates directly into your existing tools through a robust API, an MCP server for AI assistants like ChatGPT and Copilot, and plugins for Microsoft Office.
This makes Supertext a practical choice for teams that handle a high volume of translations and can't afford errors. It's used by over 1,500 brands for tasks like localizing websites, marketing campaigns, and internal documents. The promise is faster, more accurate, and more secure translations than using a generic AI translator alone, which is why it appeals to enterprises scaling their multilingual operations.
