Your phone, your meeting app, and a dozen standalone apps all promise live translation now. They're built for different jobs. Here's how to tell which one fits yours.
A few years ago, translating a live call meant hiring an interpreter or passing a phone back and forth over Google Translate. Now it's built into iPhones, Galaxy phones, Pixels, Zoom, and Teams. That's real progress, and it has made the choice more confusing. The right real-time translation app depends less on which is most accurate and more on where the conversation happens and how much is riding on it. Here's the map.
Most people need more than one. The question is which one covers the conversations that actually matter to you.
| App | Kind | Best for | Limits to know |
|---|---|---|---|
| Unicaption | Standalone copilot | Professional calls and meetings on any platform, including interpreting | Laptop or desktop, not a mobile app |
| Apple Live Translation | Phone built-in | Casual iPhone calls, FaceTime, Messages, AirPods conversations | Supported iPhones and languages only; check Apple's list |
| Samsung Galaxy AI Live Translate | Phone built-in | Casual calls on recent Galaxy phones | Galaxy devices and supported languages only |
| Google Pixel call translation | Phone built-in | Casual calls on recent Pixel phones | Pixel devices and supported languages only |
| Google Translate / Microsoft Translator | Conversation mode | Travel and face-to-face exchanges | Turn-taking, not a running transcript of a call |
| Zoom, Teams, Meet translated captions | Meeting platform | Meetings where everyone's on that platform | Host must enable it; usually paid tiers; that platform only |
Apple's Live Translation works inside Phone, FaceTime, and Messages on Apple Intelligence iPhones, and with supported AirPods for in-person conversations. Samsung's Galaxy AI and Google's recent Pixels offer similar call translation. They're convenient because they're already on the phone, with nothing to install and nothing to pay.
They're built for everyday conversations: booking a table, talking to a landlord, calling family. They translate only on that brand's phone, cover a limited set of languages, and generally don't give you a custom vocabulary or a running bilingual transcript to check against. For a doctor's appointment, a legal matter, or work calls, you want more control.
Zoom, Microsoft Teams, and Google Meet all offer translated captions, usually on paid plans, and the host has to turn them on. If your whole organization lives on one platform and the host controls the settings, they're a reasonable default. Our guide to translated captions in Zoom, Teams, and Meet covers the setup for each.
The limits show up when you're a guest on someone else's call, when a client uses a different platform each week, or when the call is a phone line rather than a meeting. See Unicaption vs Zoom translated captions for the full comparison.
Unicaption is built for conversations where a mistranslated word has consequences: interpreted calls, medical and legal conversations, client meetings, and multilingual teams. It reads your microphone or system audio, so it works beside any call. Nothing joins the call, and no host setting is needed.
Use your phone's built-in live translation. It's free, already there, and made for this.
Use Google Translate or Microsoft Translator conversation mode, or AirPods Live Translation if you have supported hardware.
Start with that platform's translated captions if your plan includes them and the host turns them on.
Use Unicaption. It works beside any call, shows the original and translation side by side, and keeps your terminology. Interpreters: see the best AI tools for interpreters.
For casual calls, the built-in live translation on recent iPhones, Samsung Galaxy, and Google Pixel phones is the easiest option. For professional calls, interpreting, or calls on any platform from a laptop, Unicaption shows live transcription with side-by-side translation in 60+ languages, keeps a custom dictionary, stores nothing, and has 30 free minutes every week.
Zoom and Teams have their own translated captions, usually on paid plans, and the host has to enable them. Unicaption works beside Zoom, Teams, Google Meet, Webex, or any other platform by reading your system audio. It shows live captions and translation in 60+ languages without joining the call or needing host settings.
Interpreters need a copilot, not a replacement. Unicaption is built for human interpreters: live transcription with side-by-side translation beside any call, built-in medical, legal, and government terminology, a custom dictionary, and nothing stored after the session. It runs in the browser, a Chrome extension, and macOS and Windows apps, with 30 free minutes every week.
Treat AI translation as support, not a certified interpretation. For medical and legal conversations, use a qualified human interpreter. Tools like Unicaption help that interpreter by putting every word on screen with side-by-side translation and a terminology dictionary.
30 free minutes every week. Works beside any platform. Nothing stored.
