Real-time AI interpreting for macOS

Your voice, in every language. In real time.

Strym turns your Mac into a simultaneous interpreter: speak your language, and your audience hears a natural voice in theirs, live on Zoom, Google Meet and beyond. Two-way translation, in real time.

  • 23 languages
  • ~1s latency

Two modes, one tool

Speak to an audience.
Or with a person.

Webinar · one-way

Your course, in every language

Lectures, presentations and live streams: your voice is transcribed, translated and re-voiced by AI. Your audience hears a smooth, real-time translation.

You speak Strym translates your audience listens

Conversation · two-way

Dialogue beyond language

Meetings, negotiations and consultations: Strym translates both ways in real time. You speak your language, they hear theirs, and vice versa, inside a normal video call.

You them · each in your own language

How it works

Three stages, one second

  1. 1

    Speech recognition

    Deepgram Nova: state-of-the-art speech-to-text with specialised models for meetings, medical and financial terminology.

  2. 2

    AI translation

    Choose your engine (Groq, Claude or Gemini) and set a backup order. If one provider fails, another takes over automatically, so no sentence is lost.

  3. 3

    Voice synthesis

    Hundreds of natural voices by Cartesia and ElevenLabs, filtered by language, for both the voice you send and the one you hear.

Features that make the difference

Built for people who actually use it

23 languages

English, Spanish (4 variants), Italian, French, German, Chinese, Japanese, Arabic and more.

Custom glossary

Your field's terminology, translated your way, in both directions. Load it from a file.

Custom vocabulary

Teach speech recognition your names, acronyms and jargon, so they are understood on the first try.

Audio routing

Headphones, speakers and a virtual device with independent volumes. Bluetooth headsets re-attach on their own.

Live statistics

Per-stage latency and session cost in real time, item by item.

Recording

Save the session's translated audio in one click, ready to share.

Built for the long haul

Auto-reconnect and a Mac that never falls asleep: a 3-hour call is business as usual.

Customisable prompt

Your tone, style and rules on top of a hardened base that only ever translates.

Privacy & costs

Your keys. Your data. Your costs.

Total privacy

Strym connects directly to the AI providers with your personal API keys. Your voice never touches our servers: Mac → provider → platform. Period.

Transparent costs

You pay providers only for real usage: a one-hour call typically costs a euro or two in API fees. The in-app meter shows it live.

No lock-in

Switch models or providers anytime, even with a custom model ID, the day it ships. Guided onboarding handles the rest.

FAQ

Frequently asked questions

Does the other person need to install anything?

No. Everything runs on your Mac. For them it's a regular Zoom, Meet or Webex call, with a voice that happens to speak their language.

How much latency is there?

About one second from the end of your sentence to the spoken translation: the rhythm of a simultaneous interpreter. The stats panel shows the real numbers for every stage.

What do I need to get started?

A Mac, API keys from the providers (free to create, most include starter credits) and the free BlackHole audio driver. The setup wizard walks you through it.

Does it work with my platform?

With any software that lets you choose a microphone and a speaker: Zoom, Google Meet, Webex, Teams, Discord, OBS and more.

Are my conversations safe?

Your audio goes directly to the AI providers you chose, with your own keys. Strym has no servers listening, recording or storing anything.
