About Keysake

Keysake is a Mac input method designed for Chinese speakers learning English. It displays relevant English expressions alongside Chinese text as the user types, enabling real-time discovery of phrasing without interrupting the writing process. The tool captures sentences, phrases, or individual words for later review, allowing users to build a personalized collection of expressions tied to their own writing context. Built-in grammar insights automatically break down saved sentences, explaining sentence structure and usage patterns to deepen understanding. The application operates entirely on-device using Apple’s translation technology, ensuring privacy by avoiding cloud processing of user input. It is currently available as a design preview for Mac with a Chinese-language interface, supporting Chinese input with English translations.
