About this app

CoreTalk turns your phone into a real-time, face-to-face interpreter. Put the phone flat on the table between you and the other person and just talk — CoreTalk listens to both sides and shows the translation on a split screen, with the far side rotated 180° so it reads perfectly for the person across from you.

FACE-TO-FACE, HANDS-FREE
• Split-screen layout: your half faces you, the other half faces them.
• Each side reads and hears the translation in their own language.
• Designed for a phone lying flat between two people.

REAL-TIME, TWO-WAY
• Both directions are translated live as each person speaks.
• Streaming captions appear as the words are still being spoken.
• Spoken translation plays automatically so no one has to look down.

AI OR HUMAN — YOUR CALL
• Manual mode: hold to talk, full control of each turn.
• Hand to AI: let the AI interpreter run the conversation automatically.
• Take over: step back in at any moment. Switch between AI and human instantly.

BUILT FOR TRAVEL & EVERYDAY
• Restaurants, markets, front desks, clinics, meetings — anywhere two languages meet.
• Swap the language pair and per-side voices in one tap.
• Conversation history you can look back on.

BRING YOUR OWN AI
CoreTalk connects to your own AI translation server (and optionally your own OpenAI key) — you stay in control of your data and your usage. No account or sign-up required to try it: open the app and tap Demo Mode to see the full experience with sample content, no credentials needed.

Your credentials are stored only on your device.
