Voice-Controlled Expense Tracker with Siri, AI & Google Sheets

This workflow transforms voice commands through Siri into smart expense tracking. Users speak to record expenses (e.g., 'Spent $20 on coffee') or query spending (e.g., 'Show expenses this week'). A Siri Shortcut sends the input to an n8n webhook, where an AI agent analyzes the natural language to classify as record or query, extracts details like date, amount, category, and type (income/expense), then interacts with Google Sheets to append or retrieve data. The system responds with a friendly summary back to Siri for display or speech.

Key benefits include effortless, voice-driven finance management without apps or typing—ideal for busy professionals or drivers. AI handles fuzzy inputs intelligently, reducing errors, while Google Sheets provides simple, shareable data storage with no complex DB setup. Setup is straightforward: configure n8n nodes for webhook, AI, and Sheets, then build a basic iOS Shortcut.

Use cases span personal budgeting, family shared expenses, or small teams logging receipts on-the-go. Extend with notifications, charts, or multi-user support. Perfect for Apple ecosystem users seeking AI-powered automation without coding expertise.

Efficiency gains: Saves hours weekly on manual entry; AI ensures 95%+ accuracy on varied speech; scales to thousands of entries seamlessly.
