CoreTalk vs Interpreter

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.

No button to hold. Just talk. When the other person speaks, you see the translation in your language; when you answer, they hear it in theirs. The app works out who is speaking on its own. Ten minutes free. After that, one purchase removes the limit. No monthly or weekly charges. ■ Where it helps ・Travelling — asking directions, ordering, checking a price ・Serving customers who don't share your language, at a shop, hotel or clinic front desk ・Counters and offices, explaining symptoms or paperwork ・Sitting down with a colleague, a neighbour or family who speaks another language ■ How it differs from other interpreter apps ・No push-to-talk. Start speaking and it starts listening; the translation keeps flowing as long as the conversation does ・No handing over your phone. Split view flips the top half 180° for the other person, so you stay face to face ・No account. No sign-up, no login. Open it and use it ・Nothing leaves the device. Speech recognition and translation both run on your iPhone. Your conversations are never sent to a server ・No time limit after you buy. A long meeting won't get cut off mid-sentence ・Works offline. After the one-time language download, it works on a plane or underground ■ Pricing ・Ten minutes free, in total (it is not a daily allowance that resets) ・After that, Pro removes the limit — a single purchase, no monthly or weekly charge ・Family Sharing supported ■ Languages English and Japanese, plus Chinese (Simplified and Traditional), Korean, Spanish, French, German, Italian, Portuguese (Brazil), Russian, Vietnamese, Thai, Arabic, Dutch and Turkish, in any pair. Only the languages your device's speech recognition and translation support are shown. ■ What it does ・Live captions. The translation appears while you are still speaking and firms up when the phrase ends ・Spoken translations, switchable for the other person and for you independently ・Split view, with the top half rotated 180° for the person across from you ・Speaker override. If the automatic detection gets it wrong, pin it to "Me" or "Them" ・Saved conversation history, shareable as text ・Large text mode, readable across a counter ・Microphone sensitivity adjustment ・The screen stays awake while you're interpreting ■ Being straight with you ・It struggles with jargon and long sentences. Short phrases translate far better ・Because everything runs on the device, the translation is not as strong as a large cloud model. In exchange it is cheap, fast, and private ・The microphone mutes while a translation is spoken aloud, so it goes more smoothly if the other person waits for it to finish ・Requires iOS 26 or later, iPhone 11 or later. An Apple Intelligence device is not required ■ Privacy The app collects no data. Neither your conversations nor your usage is sent anywhere. ■ Support Send questions and bug reports from the support page.
