Live on your desktop

Real-time speech translation,
right on your desktop.

Capture any audio playing on your PC or microphone, translate it instantly with NVIDIA Riva, Whisper, or Llama 3.1, and watch it appear as a transparent always-on-top overlay. No extra hardware. No browser tabs.

20+ languages, auto-detect System audio & microphone Works offline (Whisper)

Everything you need, nothing you don't

Built for live captions that follow what you're actually doing — gaming, meetings, foreign-language content, accessibility.

🎙️

Universal audio capture

Translates any audio playing on your PC — videos, calls, streams, meetings — or your microphone. One-toggle switch with independent volume controls.

🌐

Multi-engine ASR

Pick NVIDIA Riva for highest accuracy, Whisper for offline privacy, or Google for zero-setup speed. Switch any time without restarting.

🔤

Multi-engine translation

Llama 3.1 8B for context-aware AI translation, Google Translate for breadth, or Riva NMT for neural quality. Bring your own NVIDIA key for unlimited.

🪟

Transparent overlay

Always-on-top, draggable, resizable. Adjustable opacity, font size, bold toggle, and a Mini Mode that collapses to a single caption line.

📜

Searchable history

Every caption is saved to a glassy dark History Panel — search, jump back, and copy any line. Retention scales with your tier.
