The system calculates real returns (return minus inflation), splits each commodity, and checks if it outperforms savings. Each commodity is tagged as a good or poor hedge. The results are merged and passed to an AI model, which generates a clear, human-readable financial report.\n\n### Setup steps:\n1. Enter inflation rate and returns in the input node\n2. Configure OpenAI API credentials\n3. Set up email (SMTP or Gmail app password)\n4. Execute workflow to receive AI-generated insights\n\nThis workflow helps users make smarter financial decisions by converting raw data into meaningful insights automatically."
