What makes Cosmo different

Built for real conversations,
not one-off or superficial translations.

Cosmo is designed for ongoing back-and-forth dialogue, with controls and session tools that support more natural spoken conversations across languages.

🎙️

Live Voice Translation

Speak naturally and see each translated turn appear during the conversation, with spoken playback available as the exchange continues.

🤝

Built for Two-Way Dialogue

Cosmo is designed for sustained back-and-forth conversation, so both sides can continue speaking without treating each line like a separate translation task.

⚡

Near-Instant Response

Low-latency translation helps the conversation keep moving, so responses appear quickly enough to support more natural exchanges.

🌎

50+ Languages

Cosmo supports broad multilingual coverage for travel, business, and everyday conversations across a wide range of languages.

📚
