Keysake

Keysake is a Mac input method for Chinese speakers learning English. It shows English expressions while users type in Chinese, then lets them save words, phrases, and sentences for grammar-focused review.

Keysake

Chinese-to-English learning within everyday typing

Keysake is a Mac input method for Chinese speakers learning English. It adds relevant English expressions alongside Chinese text as you type, helping you explore how to express a message, note, or thought without leaving the writing flow to look up translations.

The product also turns everyday writing into a review collection. Users can save individual words and phrases from the interface or double-tap the space bar to save a complete sentence, then revisit saved sentences with explanations of sentence structure and grammar. Keysake currently focuses on Chinese input and English learning; broader language support is planned but not yet available.

Core features

Live bilingual suggestions

While you type in Chinese, Keysake shows corresponding English expressions alongside your input in real time, so you can discover alternatives without pausing to search.

Word and phrase capture

Hover over an individual word or phrase, right-click, and choose Save to add it to your collection.

Double-tap sentence capture

Double-tap the space bar after typing to have Keysake recognize and save the complete sentence for later learning.

Grammar insights

Review saved sentences with automatic explanations of sentence structure and grammar, including roles such as subject, predicate, and object.

On-device translation

Apple’s on-device translation technology generates English translations locally on the Mac instead of sending input to the cloud for translation.

Practical use cases

  • Drafting everyday messages

    Type a Chinese message as usual and use the accompanying English expressions to find a natural way to communicate the same thought without opening a separate translation tool.

  • Learning from personal writing

    Write an email draft or note in Chinese, capture useful wording as you go, and build a collection tied to the situations in which the expressions matter.

  • Reviewing sentence patterns

    Save a full sentence after finishing a thought, then return later to study its grammatical structure and the meaning of phrases such as “need to” or “take a look at.”

  • Keeping translation on the Mac

    Use local translation processing when working with text that users prefer not to send to a cloud translation service, subject to Apple’s on-device translation availability.
