Private AI Translator

Translate anything on Mac—across any app, one shortcut, fully offline.

Private AI Translator lives in your menu bar. Select text, hit the shortcut, and get instant translations powered by a language model running locally on your Mac. No account. No API key. No character limits. No subscription. Zero network traffic during translation.

What sets it apart • Fully offline—works on planes, in hotels, or on managed corporate Macs • Zero setup: models are bundled with the app • Supports 36 languages with automatic source detection • Your translated content never leaves your device—no accounts, no analytics, no telemetry

Seamless workflow integration • Translate selected text (⇧⌘T)—select text in any app and read the translation in the menu bar window • Quick bubble (⇧⌘P)—a small translation bubble appears next to your cursor • Translate and replace (⇧⌘R)—overwrite the selected content in place • Screenshot translation (⇧⌘O)—drag a region over any screen area, including PDFs or images, to translate the text

Output your way • Tone and context presets—formal, casual, email, technical, marketing—and custom options • Document translation preserves headings, lists, blank lines, and code blocks (for plain text files; use screenshot translation for PDFs and Word documents) • Read aloud, copy with one click, and revisit recent translations from the history menu • Clipboard integrity preserved—what you copy remains unchanged

Total control • Accessibility and screen recording permissions are optional: translation windows, document translation, and copy-paste features work without them • All shortcuts are remappable, including function keys • Arrange panels vertically or horizontally, keep the window on top, and launch at login • Nine color themes supporting light, dark, and system-follow modes • Interface languages: English, Simplified Chinese, Traditional Chinese, Japanese, Korean, French, German, Italian, Spanish, Portuguese

For developers • Optional local /v1/chat/completions endpoint (http://127.0.0.1:11434/v1)—any compatible client, whether scripts or editor plugins, can leverage the loaded models. Disabled by default and bound only to localhost.

Supported Languages Arabic, Bengali, Burmese, Cantonese, Chinese (Simplified), Chinese (Traditional), Czech, Dutch, English, Filipino, French, German, Gujarati, Hebrew, Hindi, Indonesian, Italian, Japanese, Khmer, Korean, Malay, Marathi, Persian, Polish, Portuguese (Brazil), Russian, Spanish, Tamil, Telugu, Thai, Tibetan, Turkish, Ukrainian, Urdu, Uyghur, Vietnamese

System Requirements • macOS 14 Sonoma or later • Apple Silicon (M1 or newer)—language models run on GPU via MLX • ~1 GB after installation: built-in translation models enable immediate offline use without downloads • Menu bar app: click the bubble icon in the menu bar after launching, then select "Open Translation Window"

Clear Privacy Private AI Translator makes zero outbound network requests. It comes with its own models, requires no login, contains no ads, analytics, or tracking SDKs. Everything written stays on your Mac: your preferences, your history (opt-out clears all data), and files you explicitly save.

Ideal for: reading foreign emails and documents, working offline, translating screenshots, protecting sensitive customer and legal texts from third-party servers, and anyone who prefers not to paste work content into web-based tools.
