Before checkout

Use OSS as the trial and compatibility check.

Pro is delivered after purchase and the sale becomes final when the license key is issued. Do not buy to discover whether the core workflow works on your system.

Install OSS

Verify the operating system, display session, microphone, speakers, and target applications.

Connect your actual LLM

Test the endpoint, model, streaming behavior, and network path you intend to use.

Read the license terms

Confirm the machine-use rights, version 1 update scope, final-sale policy, and support arrangement.

Buy for the Pro features

Purchase after Kokoro, wake word, persistence, personas, LAN sharing, dashboard, or local history justify the upgrade.

Pricing questions

Perpetual use, precisely defined.

Is Pro a subscription?

No. The $39 fee is charged once. There are no recurring subscription fees.

What does perpetual mean here?

You may continue using the purchased version indefinitely. Included updates cover the version 1 line only; version 2, if released, is not included.

Can I use Pro for work?

The current terms allow personal or commercial use on the purchaser’s own machine or machines, subject to the full license terms.

Can I share the license with a team?

Do not assume a single license covers unrelated users. Contact sales for group licensing and discounts.

Can I get a refund if pure Wayland does not work?

The current terms make the sale final after license delivery. Test the OSS edition on the same desktop and applications before purchasing.

Do integrations require Pro?

No. The bridge CLI, warm daemon, Piper, Faster Whisper, and the published integration contract are available in OSS. Pro adds its documented premium capabilities.

Start with the workflow

Start free. Pay once when Pro earns it.

Validate the entire core workflow in OSS, then purchase the perpetual Pro version only when its added features match your daily needs.
