Desktop Application Advantage

Unlock Ultimate Speed and Pronunciation

The BetterTTS desktop app acts as a high-performance local backend for the browser extension. By running speech synthesis natively on your device, it completely bypasses browser execution sandboxes, offloads CPU-heavy tasks from your tabs, and delivers studio-grade voice fidelity.

Compare the performance benefits of running the dedicated local application against the browser-only fallback below.
