About the Supertext API at Swiss {ai} Weeks
The Supertext API, launched in July 2025, allows users to automatically translate text and files in 28 languages – fast, reliable and secure. It also detects the language of any input with high accuracy – ideal for fully automatic workflows.
What’s more?
In its paid version, the Supertext API can do even more.
With an API subscription, you can automatically translate content from any third-party system – and bring in experienced linguists to verify the AI output in minutes.
Our goal is to build an all-in-one language workspace, where every intervention by professional linguists enhances and customises each user’s personal AI translation system.
