Frequently Asked Questions (FAQ)
Summary: Answers to frequently asked questions about using XBrush, organized by category. If you can't find what you're looking for, please use Contact Support.
1. Getting Started
Can I try it for free?
Yes, XBrush provides free credits upon sign-up. You can use the free credits to try the image generation feature directly. Some advanced features such as video generation require additional credits. For details, see the Billing Guide.
Which social logins are supported?
XBrush supports social login with Google, Kakao, and Naver accounts. You can also sign up directly with an email address and start using the service immediately after verifying a 6-digit code. For details, see the Login Guide.
How do I change the language or region?
You can change the language from the user menu in the top navigation bar. XBrush supports 10 languages including Korean, English, Japanese, Simplified/Traditional Chinese, German, Spanish, French, Portuguese, and Russian, and the change takes effect immediately. For details, see the Language & Settings Guide.
2. Credits · Billing · Receipts
What are credits and when are they deducted?
Credits are the billing unit used when performing AI tasks in XBrush (image/video/audio generation, enhancement, etc.). Generating an image deducts 10–30 credits, and generating a 5-second video deducts 20–50 credits; the amount varies depending on the task type and settings.
What is the difference between a subscription and a credit top-up?
A subscription means paying a fixed amount monthly or annually to receive credits regularly. There are 3 plans: Basic (2,000 credits), Plus (6,500 credits), and Pro (12,000 credits). For current pricing, visit the pricing page. A credit top-up is a way to purchase additional credits whenever you need them; however, due to domestic card company policies, both methods cannot be used simultaneously.
How do I get a receipt or tax invoice?
After payment, a card slip and receipt are automatically sent to your registered email. If you need a tax invoice, please contact contact@lightweight.kr with your payment details. Separate guidance is available for corporate clients with team subscriptions.
What is the refund/cancellation policy?
If you request a refund within 7 days of payment without having used any credits, it will be processed after review. Refunds are not available if even 1 credit has been used. To request a refund, please contact contact@lightweight.kr with your payment details.
What is the difference between credits and points?
Credits come from subscriptions or top-up purchases and reset or expire on a billing cycle. Points are earned from promotional events and bonuses — they are permanent and never expire. When performing a task, credits are used first; points are only consumed once credits run out. See Credit Usage History for more details.
3. Account
How do I reset my password?
Click "Forgot Password?" on the login page, enter the email address you signed up with, and follow the reset link sent to your inbox. Your new password must be 8 or more characters and include a special character and an uppercase letter.
Note: Social login users (Google, Kakao, Naver) do not have a separate XBrush password. Manage your password through your social account provider.
For more details, see the Login Guide.
Are there any bonus credits or reward events?
XBrush periodically runs promotional events where you can earn bonus points — including sign-up bonuses, referral rewards, and seasonal campaigns. Points are permanent and do not expire. Check the Rewards section in your profile page or follow XBrush announcements to stay informed about current promotions.
How do I delete my account?
Go to Account Settings via the user icon in the top-right corner, scroll to the bottom, and click "Delete Account". Account deletion is permanent — all content, credits, and subscription data will be removed. For full instructions, see My Profile.
