The first one is free. The other two are paid in USDC on Solana: pick a plan, scan the QR with any wallet app, and the upgrade lands on its own. No card, nothing stored on file.

Paid plans are settled in USDC on Solana devnet. Pick a plan, scan the QR with any wallet app, and the upgrade lands on its own — no wallet to connect, no card, nothing stored on file. Every payment is verified against the chain before anything is granted.

Limits are real numbers rather than the word “unlimited”, because generation costs real money and we would rather tell you where the edge is than surprise you at it.

Do I need an account?

Yes. Coroas is an account-based product — you sign in before you write, and your songs are tied to you rather than to whichever browser you happened to open. The Porch plan is free and takes about twenty seconds to join.

What is a Song Room?

One complete generation: heartline, structure, full draft, editorial pass, and the analysis that comes with your plan. Editing what you already have doesn't consume one.

Why not unlimited?

Because generation costs real money per request, and any plan advertising 'unlimited' is either quietly throttling you or losing money until it changes the terms. We would rather print the number.

Do I have to connect a wallet?

No. Checkout is a QR code — you scan it with whatever wallet app you already use and approve the payment there. The only place Coroas asks to connect a wallet in the browser is a Songprint, because that transaction has to be signed by you.

Who owns what I write?

You do. Coroas doesn't claim rights in your material or in the drafts it helps you make. You remain responsible for what you submit and for evaluating what comes back.

How does billing work without a card?

You scan a QR and pay 12 or 29 USDC on Solana. The plan runs for thirty days from that payment and then simply lapses unless you pay again — no stored card, no recurring charge, nothing to cancel.
