What it does
n8n Wizard 🪄 – Your personal AI assistant inside WhatsApp This workflow transforms WhatsApp into a powerful personal AI using n8n + Green-API. Send text or voice messages — the assistant understands intent and handles daily tasks automatically. Key features - 💰 Expense & income tracking — record spending, view summaries & category breakdowns (Google Sheets, append-only) - ✓ Google Tasks management — create, list, update, delete tasks & reminders - 🐦 Post to X/Twitter — write and publish single tweets or short threads - 📧 Gmail search & summaries — find recent/unread emails by sender, label, keyword (read-only) - 🌐 Real-time answers — current weather, news, exchange rates, facts via web search - 🧮 Quick calculations — math, percentages, currency conversions - 🎤 Full voice support — incoming voice messages transcribed (Whisper), replies can be spoken (TTS) How it works 1. Green-API webhook receives message (text or audio) 2. Voice → transcribed automatically 3. Main intelligent router agent selects one sub-agent/tool 4. Action executed → result sent back as text or voice (if input was voice) Setup requirements - Green-API instance (webhook + send endpoints) - OpenAI API key (chat, Whisper, TTS) - Google Sheets, Google Tasks, Twitter/X, Gmail (read scope), SerpAPI credentials Strict routing rules prevent misuse — no deletions, no guessing values, one tool per clear intent. Start commanding: “spent 3200 on groceries”, “remind dentist tomorrow”, “tweet: loving n8n!”, “weather in Lahore now”
