LinguaBoard
Multilingual Subtitle Board for macOS
Type once, communicate with the world. Enter a single sentence and instantly display translations in multiple languages side by side, just like live subtitles.
Type Once, Translate to Many
Unlike traditional translators that work one language at a time, LinguaBoard shows your text translated into 13+ languages simultaneously. All results appear as clean, color-coded subtitle cards, making it easy for each viewer to read in their own language at a glance.
Perfect for Silent Streaming
Ideal for streamers who prefer not to speak on camera. Type your message and it appears as multilingual subtitles. Share your screen in OBS or video calls.
13+ Languages
English, Chinese, Japanese, Korean, Spanish, French, German, Italian, Portuguese, Russian, Arabic, Thai, Vietnamese, and more.
Premium Text-to-Speech
Listen to any translation with high-quality voices. Adjust speaking speed and enable natural rhythm mode for realistic pronunciation.
Sessions & History
Organize your work with sessions for different topics or streams. All translations are saved and searchable for quick reuse.
Privacy First. Fully Offline.
All translations run locally using Apple's on-device Translation framework. No internet required, no accounts, no data ever leaves your Mac.
