Invoices and refunds

See your balance and transactions, buy more credits or a monthly plan, cancel a card plan's renewal, and when you can get a refund.

The Credits page shows how many credits you have, what you've spent them on, and your monthly plan (if you have one). Buying more credits or a plan happens on the Pricing page.

To open Credits: click your account name at the bottom of the left sidebar and choose Credits (or go to /credits).

Read your balance

The balance box splits your credits into four figures:

Available: the credits you can use right now.
Free: credits you were given.
Purchased: credits you bought — they never expire.
Held: credits held for work still running; spent or given back when it ends.

When credits are spent, Free credits go first, then Purchased credits.

If you're on a monthly plan, a plan card sits above the balance: the plan name, the days left and the allowance left this month.

The Credits page: the monthly plan card at the top, the balance box with Available / Free / Purchased / Held, the "Buy more credits or an image plan" box with the "See pricing" button, and the Transactions table below

View your transactions

The Transactions table lists every change to your credits, newest first, with the Time, Type, Description, Credits and Balance (balance after the transaction) columns.

Filter by type: All, Spent, Refunded, Top-up, Bonus.
Several identical entries in the same minute are grouped into one row with a count (e.g. "×5").
Rows with a ? icon: hover it to see how the credits split between parts (e.g. Video export, AI images, AI voice).
Click Show more at the bottom of the table to load older transactions.

Buy more credits or a monthly plan

Step 1. Open Pricing

On the Credits page, click See pricing. The Pricing page has the credit packs, the monthly image plans and the price of each action.

Step 2. Pick a pack and how to pay

Choose a pack or plan, then one of two ways to pay:

Vietnamese bank transfer: scan a QR code; credits (or the plan) arrive in seconds.
Card or wallet: pay in US dollars on the payment page. Prices exclude tax.

Step 3. Wait for the confirmation

After paying by card you're taken to a confirmation page. It usually takes a few seconds, then it says … credits added or … plan activated. If after a minute it says Payment not received yet: if you paid, your credits will arrive by themselves within a few minutes and you can leave the page; if you didn't pay or stopped halfway, click Try again. If a payment doesn't go through, you're not charged for that attempt.

Card-paid monthly plans and cancelling renewal

A monthly plan paid by card renews every month until you cancel. The plan card on the Credits page says Renews on … — … (the next date and amount).

To stop the renewal:

On the plan card on the Credits page, click Cancel renewal.
Confirm with Cancel renewal (or Keep renewal if you change your mind).
The plan card now says Renewal cancelled — yours until ….

The plan stays until the paid period ends, then your card is not charged again. The paid period is not refunded.

When you can get a refund

A summary of the Refund policy (the full policy is what applies):

Unused credit packs: within 14 days of purchase, if none of the credits from that purchase have been used, you get a full refund. Credits you already had count as used first.
System failures: images, video scenes or posts that fail because of our system are refunded in credits automatically, no request needed (see the Refunded filter).
Completed results you're not happy with: not refunded — you can regenerate just the part you want to change.
Subscriptions: cancel the renewal at any time; the rest of the current period is not refunded.
Free and promotional credits: no cash value, not refundable.
Mistaken bank transfers (wrong reference or amount): contact us within 30 days.
