Realtime AI interpreter
between two people.
HeyLingo listens to your conversation, understands what was said, and speaks the translation naturally in the other language — like a human interpreter sitting between you.
Built for real conversations
Walkie, continuous, and table modes. Eleven translation moods. Thirty language options and variants. All wrapped in a UI that fades into the background so the conversation can come forward.
Realtime voice in, voice out
Speak naturally and hear the translation back in a clear voice, with transcripts that keep both sides easy to follow.
30 languages and variants
English (US, UK, Australia, India), Portuguese (Portugal, Brazil), Spanish (Spain, LatAm), French (France, Canada), German, Italian, Dutch, Polish, Russian, Ukrainian, Turkish, Arabic, Hindi, Bengali, Tamil, Telugu, Marathi, Mandarin, Japanese, Korean, Indonesian, Vietnamese, Thai, and Dog Mode.
Eleven moods
Friendly, professional, casual, confident, local-native — change the tone without ever changing the meaning.
Walkie · Continuous · Table
Hold-to-talk like a walkie. Open mic that handles its own turn-taking. Phone-flat-on-the-table mode for two people at dinner.
History on-device
Every session is saved locally with original and translated transcripts. Revisit, copy, delete. Nothing in the cloud.
Built with privacy in mind
HeyLingo keeps your experience focused on the conversation. Audio is used for live interpretation, and saved transcripts stay on your device.
How the app works
Start a conversation, speak naturally, and let HeyLingo guide each turn with voice, transcript, and translation.
Choose two languages
Pick your language and the other person's language, then swap directions any time.
Select the conversation mode
Use Walkie for turn-by-turn control, Continuous for open conversation, or Table when the phone sits between two people.
Speak naturally
HeyLingo listens, shows the original transcript, and prepares the translation while you keep the conversation moving.
Hear the translation
The translated voice plays back, the transcript stays readable, and your conversation history is saved on device.
Privacy
Audio you speak is sent to HeyLingo's AI translation service for live interpretation. HeyLingo does not store your audio. Transcripts are saved only on your device, only when a session ends.
