To ensure fair usage and maintain service quality for all users, Cellyn AI uses a daily credit system. Each day you get 10 credits that reset at midnight CEST (Central European Time).
Each AI-powered request uses 1 credit. Credits reset daily at midnight CEST. Your current usage shows above the chat input.
