Voice-controlled expense tracker with Siri, AI and Google Sheets

🎯 What It Does:

This project lets you talk to Siri (via Apple Shortcuts) and record or query your daily spending. The shortcut sends your message to an n8n Webhook, which uses AI to decide whether it’s for writing or reading finance data, then replies with a human-friendly message — all powered by n8n + AI + Google Sheets.

🌐 PART 1: n8n Setup

🧩 1. Create a Webhook Trigger in n8n • Add a node: Webhook • Set HTTP Method: POST • Set Path: siri-finance • Enable “Respond to Webhook” = ✅

🧠 2. Add AI Agent Node (e.g. OpenAI, Ollama, Gemini) • Use system prompt like:

You are a finance assistant. Decide if the user wants to record or read transactions. If it's recording, return a JSON object with date, type, name, amount, and expense/income. If it's reading, return date range and type (Expense/Income). Always reply with a human-friendly summary.

• Input: {{ $json.text }} (from webhook) • Output: structured json.output
