Spokio

Spokio is a fully offline text-to-speech app for macOS that generates natural voice audio, clones voices, and exports in MP3/WAV/AIFF/M4A — all without ever sending your data to a server. Powered by the Chatterbox Turbo engine with Neural Engine acceleration, it runs entirely on your Mac with no internet required. No analytics, no tracking, no telemetry. Free tier available; Pro lifetime for $49.99 unlocks unlimited voice cloning, batch export, background processing, and queue management. Requires macOS 15.6+, Apple Silicon or Intel. Built by an independent developer for privacy-conscious creators.
