Core practice stays accessible.
The public sample is available now. These are the planned release allowances; paid checkout is not yet available.
Free
US$0
Core practice tools, saved progress and 20 app-funded AI credits per calendar month in UTC.
Plus
US$9 / month
The same core practice tools, with 500 app-funded AI credits per paid billing month.
What counts as one credit?
One complete performance review with recommendations, or one aural coaching response. Credits do not roll over. Normal practice, deterministic feedback and saving remain available when AI credits run out.
Families and personal keys
Planned family accounts share the adult billing owner’s allowance; child accounts do not create extra free credits. Family access requires verified guardian consent and supported-country eligibility. Optional personal OpenAI keys are planned for adults’ own activity, with provider usage billed separately.
Billing and cancellation
Before paid launch, checkout will show the total charge and applicable billing terms. Cancellation will keep Plus access through the paid period. No payment is collected from this preview.
