π LiveLingo
Your words, any language, zero cloud. Instantly.
A privacy-first, AI-powered desktop translator that lives in your menu bar.
Press a hotkey β type β get your translation β send it. All offline. All local. All yours.
Why LiveLingo?
You're chatting with a colleague in Tokyo. Mid-conversation, you need to reply in Japanese β but your Japanese isβ¦ creative at best. You could open a browser, navigate to some translation site, copy-paste, wait for the response, copy-paste againβ¦
Or you could just press Ctrl+Alt+T.
LiveLingo pops up as a sleek floating overlay β right where you're working. Type your message, get an instant AI translation, and hit Send. The translated text lands directly into the app you were using. No tab-switching. No copy-paste gymnastics. No data leaving your machine.
π‘ Think of it as having a personal interpreter sitting inside your keyboard.
β¨ Features
π 100% Offline & Private
Your text β and your voice β never leaves your computer. LiveLingo runs local AI models for both translation and speech recognition: Gemma 4 26B-A4B MoE (Mixture-of-Experts, ~26 B-class quality at ~4 B-class latency) for translation, and sherpa-onnx (Cohere Transcribe 14-Lang or SenseVoice CJK-tuned) for speech-to-text. No API keys, no cloud services, no "we may use your data to improve our products" surprises.
β‘ Ridiculously Fast
Translation in ~300ms. The overlay appears instantly with a global hotkey. Type, translate, send β all in one fluid motion.
π 10 Languages
Chinese, English, Japanese, Korean, French, German, Spanish, Russian, Arabic, and Portuguese. Mix and match source and target languages freely.
π― Smart Text Injection
Two modes to fit your workflow:
- Paste Only β drops the translation into your clipboard
- Paste & Send β pastes AND hits Enter for you (perfect for chat apps)
ποΈ Voice Input
Talk to LiveLingo instead of typing. Powered by sherpa-onnx with two interchangeable engines:
- Accuracy First β Cohere Transcribe (14 languages, top of the Open ASR Leaderboard, ~1.6 GB)
- Multilingual First β SenseVoice Small (δΈ / η²€ / θ± / ζ₯ / ι©, on-model language detection, ~228 MB)
Switch engines anytime from Settings β Speech β the active model card shows exactly what will run, with a one-click jump to the Models tab when a download is missing.
πͺ Beautiful Floating Overlay
A frosted-glass overlay that floats above everything. Drag it, resize it, adjust its transparency from 10% to fully opaque. The text automatically adapts contrast based on your opacity setting β readable on any desktop background.
π₯οΈ Cross-Platform
Native experience on both Windows and macOS. Platform-specific hotkey hooks, text injection, and UI polish on each.
π Auto-Update
Built-in update system via Velopack keeps you on the latest version without lifting a finger.
