Top-up
Prompt2CAD is pay-as-you-go. No subscription, no recurring charge, no auto-renewal. You top up when the balance is low; credits never expire.
How to top up
- Click the credit chip in the header, or click any gated export and accept the paywall dialog's offer, or ask the agent to top up.
- The flow redirects you to Stripe Checkout in a new tab.
- Pick the amount (the minimum is $10), enter card / Apple Pay / Google Pay details.
- Stripe handles the payment; on success it redirects back to
/app?checkout=successand the credits land within seconds.
If you cancel out of Stripe Checkout, you land at /app?checkout=cancelled and nothing happens. No partial charge, no half-state. Try again whenever.
Conversion rate
1 cent = 1 credit. So:
| You pay (USD) | You get (credits) | Approx. generations | Approx. iterations |
|---|---|---|---|
| $10 (minimum) | 1,000 | ~33 | ~66 |
| $25 | 2,500 | ~83 | ~166 |
| $50 | 5,000 | ~166 | ~333 |
| $100 | 10,000 | ~333 | ~666 |
The Stripe product description lists both numbers: "~33 new designs · or ~66 refinements on existing models."
Currency
Charges are processed in USD through Stripe. Your card statement will show a USD line-item; if your card is denominated in another currency, your bank applies its own exchange rate (and sometimes a foreign-transaction markup). That markup is your bank's, not Prompt2CAD's.
Stripe also adds automatic tax based on your billing address.
Payment methods
Whatever Stripe Checkout offers in your region:
- Cards: Visa, Mastercard, Amex, JCB, Discover.
- Wallets: Apple Pay, Google Pay, Link.
- Bank: SEPA Direct Debit (EU), ACH (US).
- Regional: iDEAL (NL), Bancontact (BE), giropay (DE), Klarna where available.
Prompt2CAD doesn't see your card details — Stripe handles the entire payment surface.
What top-up unlocks
The first time you top up, two things happen:
- Credits land on your balance. Immediately.
- The export paywall opens. Permanently, for the lifetime of your account. STEP, DXF, GLB, DAE, OBJ, STL exports become free actions for you from then on.
The gate is one-way. There's no "subscription lapsed" state. If your credits run out later, you only have to re-top-up to keep using the app — exports remain unlocked.
Multiple users on one account
Top-up is per account, not per user. If you share a Google account with a colleague, you share the balance and you share the export gate. If you want separate balances, use separate Google accounts.
Receipts and invoices
Stripe sends a receipt to your email on each charge. For a VAT invoice (EU business buyers), reply to the receipt asking for one — Stripe can issue one automatically once you provide your VAT ID. You can also retrieve receipts later from the link in the original email.
Promo / referral codes
Prompt2CAD does not currently issue promo codes through the in-app flow. If you've been given one out-of-band (e.g. comped credits as part of a partnership), it's applied directly to your balance, not through Stripe — you would see the credits appear without a Stripe receipt.
Failed payments
Stripe declines a card for many reasons (insufficient funds, geo-restriction, 3DS challenge timeout). The Checkout page shows the decline reason. Try again, try a different card, or email support if the issue persists.
