Questions

Before you ask support

What happens when I run out of AI requests?

Nothing happens to your synth. Every module, patch, timeline and preset keeps working offline, forever. Only new hosted AI generations pause until your allowance resets — or you upgrade.

Is the synthesizer itself free?

Yes. The Free plan is the full instrument — every oscillator, filter, envelope, effect, wavetable warp mode, the timeline, and the mixer — with no time limit and no account required. What's metered is hosted AI generation (patches, automation, and arrangement).

Does the local Ollama mode really keep my prompts and patches on my machine?

Yes. When Agent Synth is pointed at a local Ollama model, the whole describe-and-patch loop runs on your machine. No account, no upload — prompts and patches never leave the computer they were made on. The only thing the app can send is anonymous usage statistics, which are off unless you turn them on (see the privacy policy).

Can I get a refund?

Yes, within the terms of our refund policy. See /refunds for the details.
