This n8n workflow creates an intelligent AI-driven finance assistant that integrates with Siri and Google Sheets, enabling voice-activated expense recording and account queries. The process begins with receiving user input via a webhook triggered by Siri or a custom iOS Shortcut. The input is processed by an AI agent, which determines if the user wants to record a new expense or read account information. Based on the decision, the workflow directs the AI to either append a new record to Google Sheets or fetch and summarize existing data, respectively. The workflow includes formatting steps for input and output, memory management for conversational context, and clear instructions for setup on both the server (n8n) and iOS device, making it highly practical for managing personal finances hands-free.
