Check your Mac before buying

Requires macOS 15 or later and Apple Silicon (M1 or newer). Intel Macs are not supported.

Cloning, Voice Design, and other optional models require at least 16 GB unified memory and additional downloads. Estimated model downloads include about 1.7 GB for Qwen3-TTS Base and 2.3–4.5 GB for Voice Design. Allow extra disk space for runtimes, setup, and generated audio.

Local generation and internet access

Speech generation runs locally after setup. Your scripts and audio are not uploaded to a cloud service for generation.

Internet access is required for activation, periodic license validation, downloads, updates, community browsing, and diagnostics described in the Privacy Policy.

License, delivery, and refunds

Your download and license key arrive by email. A purchased license is required; this is not a free trial.

Your purchase includes perpetual access to the version you buy and free updates for that version. Future versions and upgrades are not guaranteed. One active Mac per license; contact support when moving to another Mac.

7-day money-back guarantee, subject to the Refund Policy.

Model licenses and voice permissions still apply, including for commercial projects.
