Two thumb buttons
One button for your language, one for theirs. Hold to speak, release to send. You run both sides of the conversation from a single phone.
AI Voice Translator
Hold up your phone. They don't touch it.
Psybeam is a real-time voice interpreter for travel: you hold the phone and run both sides of the conversation. Hold your button and speak — they hear it aloud in their language. Hold theirs while they answer — you hear it in yours. The stranger in front of you never touches your phone.

One button for your language, one for theirs. Hold to speak, release to send. You run both sides of the conversation from a single phone.
Natural speech-to-speech that follows the speaker's own voice. No typing, no reading a script, no teaching anyone the app.
Your words, in their language, rotate to face the person opposite you. Their reply stays upright for you to read.
Cross a border and Psybeam suggests the local language from your location, so you start talking instead of digging through menus.
Start with free minutes, then buy a pack only when you need more. No recurring charge and no trial trap.
Audio is streamed to OpenAI only to translate it. OpenAI does not use it to train models, though it may briefly retain API audio for abuse monitoring. Your transcript never leaves your phone.

less psybeam/README
Psybeam is a real-time AI voice translator for travel. Hold a button, speak, and the person in front of you hears it spoken aloud in their language. Hold the other button while they answer, and you hear them in yours. No typing, no reading, no app on their phone.
It is a live speech-to-speech interpreter in your pocket: it detects what was said, translates it as you speak and speaks it back in a natural voice that follows the speaker. Order food, ask directions, check into a hostel, talk to a pharmacist or a taxi driver, face to face, in seconds.
• Voice to voice, live. Not a text translator with a speaker button: the translation is spoken as it happens.
• One phone, one operator. You hold the phone and run both directions from two thumb buttons. The other person just listens, then speaks when it's their turn.
• The translation faces them. Your words, in their language, rotate to face the person across from you. Their reply stays upright for you.
• No account, no sign-up. It opens straight to talking.
• No subscription, no trial trap. Start with free minutes, then buy a minute pack only when you need more. Never a recurring charge.
• Your conversation stays on your device.
English, Spanish, French, German, Italian, Portuguese, Dutch, Russian, Polish, Turkish, Greek, Arabic, Hebrew, Hindi, Japanese, Korean, Chinese, Thai, Vietnamese, Indonesian, Finnish and Swedish. Any pair, either direction.
1. Pick your language and theirs, or let Psybeam suggest the local language from where you are as you cross a border.
2. Hold your button and speak. Release, and it says it aloud in their language.
3. Hold their button while they reply. You hear the answer in your language.
That's the whole app.
Markets, restaurants, hotel and hostel desks, taxis, pharmacies, train stations, asking a local for help. Any moment when you and someone else don't share a language. Works with Voice Isolation for noisy streets and cafés.
Audio is streamed directly to our cloud translation provider only to translate it and is never routed through our servers. Your transcript never leaves your phone. You can withdraw cloud AI consent at any time in Settings.
iPhone, iOS 18 and later. Open it, hold a button, and have your first conversation across a language barrier in seconds.
./psybeam --faq

No. Psybeam opens straight to talking with no sign-up. You can sign in with Apple later to link your account, but it is never required to use the app.
No. You hold the phone and run both sides. The person you are talking to just listens, then speaks when it is their turn, with an on-screen prompt inviting them in their own language.
22 languages, spoken aloud in both directions: Arabic, Chinese, Dutch, English, Finnish, French, German, Greek, Hebrew, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Swedish, Thai, Turkish and Vietnamese.
Your conversation transcript stays on your phone and is never uploaded anywhere. To translate your speech, the audio itself is streamed to OpenAI in real time; OpenAI does not use that audio to train its models, though like any API traffic it may be retained briefly for abuse monitoring. Psybeam's own servers never see or store your audio or transcript.
No. Live voice translation needs a connection, since the speech is translated in real time by a cloud translator.
