💳 Daily Credits

To ensure fair usage and maintain service quality for all users, Cellyn AI uses a daily credit system. Each day you get 20 credits that reset at midnight CEST (Central European Time).

📊 How Credits Work
• Each AI-powered request uses 1 credit
• Credits reset daily at midnight CEST
• Your current usage shows above the chat input

What Does NOT Use Credits

Simple conversational messages are free and don't consume credits:

👋 Greetings: "Hi", "Hello", "Good morning"
👍 Acknowledgments: "OK", "Got it", "Thanks"
✅ Approvals: "Approve", "Reject", "Cancel"
👋 Farewells: "Bye", "Goodbye", "See you"

What Uses Credits

AI-powered operations that analyze, create, or modify your spreadsheet:

📊 Building financial models (DCF, LBO, etc.)
🔢 Creating and explaining formulas
🧹 Data cleaning and transformation
📈 Analysis and projections
🌐 Translation and formatting
💡 Tip: Chain multiple operations in one request (e.g., "Clean the data and create a chart") to maximize your credits!
