Language AI is a desktop companion that lets you translate, fix grammar, refine tone, or run any custom prompt on selected text — without leaving the app you're in. Highlight, hit a hotkey, and the AI handles the rest.
We preserve context, register, and idiom. A polite Japanese email stays polite in English. A casual French message keeps its warmth. Literal word-for-word is rarely what you want — and rarely what we give you.
Not today. The AI models run remotely, so an internet connection is required. The app itself is lightweight and lives in your menu bar.
Yes. We don't store the content you process. The only exception is when a jailbreak attempt is detected and we issue a warning — full details in our privacy policy.
50+ at last count, including English, Spanish, French, German, Mandarin, Japanese, Korean, Arabic, Indonesian, and more being added based on user requests.
