What is Zhiyun?
Zhiyun Literature Translation is a desktop translation tool designed for the scenario of reading scientific research literature. Its official website summarizes its positioning with three words: top-tier, secure, and conscientious. It comes with a built-in PDF reader; you can get a translation by selecting text with a swipe, eliminating the need to switch back and forth between the reader and translation web pages. The official statement says that the server does not cache any private content, and users always have full control over their literature, which can be discarded at any time. This is an important consideration for users handling unpublished research materials.
Who is it for?
- Graduate students and researchers: They need to read a large number of English literature and hope to complete reading, translation and annotation in the same software.
- Learners who need in-depth reading: With the help of the locked translation function, they can check words while reading the translation, and understand the details and expressions of the original text more carefully.
- Users with intranet or custom interface needs: They hope to access their own translation services or local models through custom APIs.
- Researchers concerned about document privacy: They do not want the content they read to be uploaded and stored, and they value the official commitment to local processing and no caching more.
