Credits System

Credits are the platform's virtual balance, used for AI drawing, tipping and more. Understanding balance, earning and spending helps you plan usage.

Balance & ledger

• Balance = user.credits, viewable in the Account Center.
• Details are recorded in credit_ledger and shown in Credit Ledger.
• Free batches credit_batch expire FIFO after 31 days; tip earnings are permanent.

How to earn

• Daily check-in: claim at Check-in / Earn.
• Invite friends: both sides get a reward on success (see Invite Friends).
• Platform rewards: events or compensations, labelled "platform reward".

How to spend

• AI drawing (non-BYOK) consumes per call.
• Tip work authors (see Favorite & Tip).
