What a custom persona generation costs
One monthly credit if you have one, otherwise 12.75 Coins.
The short answer
A Custom Persona generation uses one of your monthly subscription credits if any remain. With none left, it costs 12.75 Coins from your balance.
The generate button tells you how many credits you have left, so you see which of the two you are about to spend before you press it.
Credits first, then Coins
The order is fixed: credits are used while they last, and Coins only when they do not. You do not choose between them on each run.
For how a monthly credit is obtained, the Custom Persona page is the place to check, since this page only describes what that page states. For the Coin side, what Cock Coins buy lists every price on the site and the ways to top up.
Why there is no free tier
An account is required for Custom Persona and there is no free allowance. The reason is the history: every generation is attributed to you and saved there, which cannot happen without an account.
That is also what makes the cost easy to reason about. You are paying for a saved, attributed result you can come back to, not for a throwaway preview. Where your cock ratings are kept shows where it ends up.
Seeing the figure before you pay
The cost is visible on the generate step rather than revealed afterwards. That matters: the UK Competition and Markets Authority’s guidance on unfair commercial practices describes drip pricing as showing an initial price and then introducing additional fees as the consumer proceeds.
If you are weighing this against a built-in judge, custom persona vs built-in AI judge compares what each one gives you.
A worked example
Suppose you have two monthly credits left. Your first generation uses one and your second uses the other, so neither touches your Coin balance. Your third generation, with no credits remaining, comes out of your balance at 12.75 Coins.
If you have no credits at the start, every generation is 12.75 Coins. Either way the button shows what you are about to spend before you press it.
What this means for how you use it
Because a generation is saved to your history and cannot be undone by retrying for free, change one setting at a time and treat the first run as a trial. The ten custom persona tones compared is a useful place to decide the tone before you spend.
If your balance is short when you generate, the top-up window opens instead of failing. Nothing about the persona is lost in the process.
Questions people ask
Does it refund if I am unhappy with the tone? This page cannot promise that, and the site states no such rule for Custom Persona. The sensible protection is to use the Sample tab first and to change one setting at a time.
Can I pay in Coins even if I have credits? The order is credits first while any remain, so the button will use a credit. The figure it shows is the one to go by.
Where do I see my balance? Your Coin balance is the same one that pays for everything else on the site, so what a judge rating costs is a useful comparison if you are deciding where to spend it.
