Real App UI

Not chat bubbles.
Live transcript.

Each turn shows the original speech at low opacity, with the bold translation below — so you read the translation naturally while seeing what was said.

・

Original text — subtle, always visible

The speaker's words at 55% opacity. You know what was said, but the translation takes center stage.

A

Each speaker gets a color

Speaker A uses the primary accent (pink in the midnight theme). Speaker B gets the secondary (teal). At a glance, you know who said what.

⚡

Streaming tokens appear as you speak

New words blur in with a 150 ms fade as they arrive from Soniox's speech engine. No lag, no jumping — just natural flow.

・ 日本語で話してもいいですか？
Can I speak in Japanese?
・ Of course! Go ahead.
もちろん！どうぞ。
・ ありがとうございます。このアプリ、すごいですね。
Thank you. This app is incredible.
・ Right? I use it every day for work…
毎日仕事で使っています…

How It Works

As simple as a conversation

No Wi-Fi sharing, no external hardware, no apps for both people — just one iPhone and two voices.

1
Place your iPhone
Set it on the table between two people. The mic picks up both voices from across the table.
2
Choose two languages
Pick from 60 languages using the language pills at the bottom. Each person speaks their own language.
3
Tap the mic and speak
LiveHi detects which language is being spoken and routes the translation in real time. No manual switching.
4
Read and listen
Both sides see the transcript on screen. TTS reads the translation aloud. The conversation flows naturally.
Languages
