Choose a Plan for Your Team. Use What You Need. Use What You Need.

Each plan has a monthly fee and included credits. Credits are deducted according to your service usage.
What you pay = ① the plan fee (fixed, monthly) + ② purchased credits (charged when you top up).

ㆍCredits are the currency inside the service. 1 Credit = US$1, fixed.
ㆍEvery plan includes credits each month (Free 5, Pro 10, Business 100). No additional credit purchase is needed while your usage stays within those credits.
ㆍWhen you need more, top up in blocks of 10 Credits (US$10) or 100 Credits (US$100).
ㆍEach job deducts the service rate, for example video analysis at 0.15 Credit per minute or AI translation at 0.10 Credit per 100 characters.

It depends on which credits.
ㆍPlan credits (Free 5 / Pro 10 / Business 100) reset on your monthly subscription renewal date. Unused plan credits expire at that time.
ㆍPurchased credits stay. They never expire.
Plan credits are always spent first, so a light month never costs you the credits you bought.

No. Stored data is kept and only new uploads pause. Top up and you continue right where you left off.

1. Payment method
ㆍWe only support credit card payments.
ㆍThe Free plan does not require a credit card.
2. Billing
ㆍThe plan fee is billed monthly. Extra credits are charged when you top up.
ㆍThe billing period is counted in days. For example, if you start on the 25th, the next billing date is the 25th of the following month.
3. Changing plans
ㆍUpgrade: the new plan is charged in full at the time of the upgrade, and your billing date moves to that day.
ㆍDowngrade: you keep the current plan until the next billing date, when the downgrade takes effect. It is a reservation you can cancel before then.
ㆍCancellation: your status changes to unsubscribed immediately. Projects created before cancellation keep working, and purchased credits are kept.

1. Payment cancellation is available within 7 days of the payment date, provided none of that month's plan credits have been used.
2. If the service differs from its description or advertisement, or is not delivered as agreed, you may request cancellation within 3 months of the service date or within 30 days of becoming aware of the issue.
3. Within 3 business days of receiving your request we ask the payment provider to stop or reverse the charge. Refunds go back to the original payment method.

LETR AI never uses customer data to train its own models. Only at the customer’s request and under a separate agreement do we supply a dedicated model trained on that customer’s data.
Our operating policy also prohibits sharing customer data for external providers’ general-purpose model training or improvement.

Because there are two processing paths.
ㆍThe layer path (keep the artwork, replace only the text layers) uses no generative AI, so the Synthesis.Image rate does not apply.
ㆍThe generative path adds 0.12 Credit per panel.
Decide the path first when requesting a quote.

Yes. Upload and management APIs are provided, and they apply from your first project. There is no extra charge.

Nothing. Existing contracts keep their terms. New sign-ups are on the credit-based plans only. If you would like to switch, let us know through the contact page.
