AI simultaneous interpreter·64 languages

Interpreted as you speak.Tap once. Then just talk.

A simultaneous-style AI interpreter that doesn’t wait for the end of the sentence. Pick any two of 64 languages — it hears which one is being spoken.

Speak either language. It hears which one and interprets into the other, in subtitles and voice. No buttons to press mid-conversation.

The interpreting screen (demo). It hears which language is spoken and gives the translation as subtitles and voice.

Performance

  • 95% of sentences began translating before the speaker finished
  • 88% were fully translated within 1 second of the speaker finishing
  • 64 languages, in any pairing

95% (38 of 40) and 88% (35 of 40): our own measurement (October 2026), streaming 40 real recorded sentences from a public multilingual speech dataset in real time (20 Japanese→Vietnamese, 20 Vietnamese→Japanese; median length about 10 seconds).

Features

Translates mid-sentence

Like a simultaneous interpreter, it doesn’t wait for the sentence to end. The translation appears as you speak and is refined as you go — even through long explanations.

Automatic language detection

Speak either of your two languages; Interpres detects which one and translates into the other. Original and translation stay side by side, ready to export as text or JSON.

Glossary

Add company, people and product names or technical terms, and those words are recognised more reliably (paid plans).

Questions

Do I need to sign up?

No. Open it and try it for 5 minutes, no account needed. To keep going, create a free account — no credit card, 10 free minutes every month.

What do I need?

A phone or computer with a microphone, and a browser. Nothing to install, no earbuds.

Do we switch languages before each turn?

No. Speak either of the two languages you picked; Interpres recognises which one and translates into the other.

Is the audio of our conversation stored?

Audio is used only to interpret and is not stored. Subtitles from sessions you run while signed in on the web are saved to your account so you can read them back, and are erased if you delete your account.

Does it work without a connection?

No. Speech is sent to our servers to be translated, so you need 4G, 5G or Wi-Fi.

How accurate is it?

The translation appears while you speak and is refined as the sentence unfolds. In our own tests, 88% of sentences were fully translated within 1 second of the speaker finishing. Names, companies and technical terms are recognised more reliably once you add them to the glossary (paid plans).
