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. Two-way translation, in real time.

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, all within a normal video call.
You ↔ them, each in your own language
How it works
Three stages, one second
1 • Speech recognition
Deepgram Nova: state-of-the-art speech-to-text with specialized models for meetings, medical, and financial terminology.
2 • AI translation
Choose your AI engine—Groq, Claude, or Gemini—and set a backup order. If one provider fails, another takes over automatically, so no sentence is lost.
3 • Voice synthesis
Choose from hundreds of natural voices by Cartesia and ElevenLabs, filtered by language, for both your voice and the one you hear.

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’s released. Guided onboarding handles the rest.
