KeyAct translating explicitly selected English text into Russian in a light-theme menu-bar popover — Native KeyAct interface with an illustrated macOS menu bar. Language support depends on the selected tool and resources on your Mac.

Start with your languages

Choose the source and destination explicitly. The setup assistant checks resources for each tool; KeyAct never silently swaps in another language.

Understand language resources →

Explore, then use the word

Related words, word classes, macOS spelling and dictionary lookup. A bundled offline conjugation catalog covers verbs in 14 languages, not every word in those languages.

Keep the thought

With Full Access, save audio, transcribe through an available on-device speech route, or do both. Choose the exact recognition language before recording.

Set up a voice note →

Make it yours

Choose visible tabs, shortcuts, window height and theme. Add URL or HTTP actions; the App Store edition also supports executable scripts you install yourself.

What you need to know

The App Store edition uses text you type or copy to the clipboard. Voice Note records in KeyAct; it does not dictate into another app's text field.

Apple's translation, word-analysis, dictionary and speech resources have different language coverage. Some need an initial download; not every Apple resource has an in-app installer. Related words are not guaranteed interchangeable synonyms, and Context is not a complete grammar checker. Optional online dictionary fallback and your HTTP actions require internet.

The interface is currently in English. Russian setup and troubleshooting help is available. The full local edition can run typed shell commands and use Accessibility; those capabilities are not part of the sandbox App Store edition.
