Ruby Lens

Hear Any Sign or Plaque, in Your Language
Point. Snap. Listen — instantly.

What is Ruby Lens?

Standing in front of a museum plaque, monument sign, or exhibit label written in a language you don’t read? Ruby Lens turns your camera into a translator you can listen to. Point at any sign, plaque, or menu, snap a photo, and hear it read aloud in your language within seconds.

Built for travelers, museum visitors, and anyone who’d rather listen to a translation than squint at a screen — Ruby Lens also works as a full photo translator for menus, street signs, documents, and more, across 80+ languages.

Key Features

🏛️ Built for Plaques & Signs

Made for the moments a paid audio guide doesn’t cover — museum plaques, monument signs, and exhibit labels. Snap a photo and hear it translated instantly.

🔊 Hear It, Don’t Just Read It

Every translation comes with natural AI-generated audio — a pocket audio guide that works on any plaque or sign, anywhere.

📷 Snap & Translate Anything

Beyond plaques and signs, Ruby Lens works as a full camera translator — menus, street signs, labels, and documents in 80+ languages.

📴 Works Offline

No signal at a remote historical site? No problem. Scans save locally and sync automatically when you reconnect.

📜 Scan History

Every plaque, sign, and menu you translate is saved, so you can revisit it later — great for building a travel journal.

🔒 Secure & Private

Sign in with your Google or Apple account. Your data stays on your device — we never sell or share your translation history.
