Read full description

OpenRaven is a real-time voice translator built for one thing: getting out of your way. Tap once. Speak naturally. Watch your words turn into another language as you talk — then tap to hear the translation read aloud. No menus to dig through, no clutter, no noise. Just a single calm screen and a translation that keeps up with the conversation. WHO IT'S FOR Travelers ordering at a counter. Friends bridging a language gap over dinner. Anyone who needs to understand and be understood, right now, without fumbling through a complicated app. HOW IT WORKS • Tap the orb and start speaking — your speech is transcribed live and translated on the spot. • Tap the flag to switch which language you're speaking. Switching mid-conversation is instant, so back-and-forth dialogue flows naturally. • Tap the speaker icon on any line to hear the translation spoken back — perfect for showing the other person what you mean. • Point your camera at a menu, sign, or document to translate text from a photo. • Type or paste text directly when speaking isn't an option. EIGHT LANGUAGES English, Chinese, Japanese, Korean, French, German, Spanish, and Italian — translate freely between any pair. PRIVATE BY DESIGN Translation happens on your device using Apple's built-in Translation framework. After the first one-time language download, translations work offline with zero latency and nothing to send away. We don't build a profile on you, and there are no ads. GENUINELY FREE OpenRaven is free to use, with 30 minutes of voice translation every day. Your daily minutes reset automatically — there's no subscription, no paywall, and no credit card. Camera and typed translations don't count against your voice minutes at all. BUILT WITH RESTRAINT Pure black-and-white. SF Pro typography. A single breathing orb at the center. Every screen is intentional, quiet, and production-grade — the opposite of the cluttered translation apps you've tried before.
