Description
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
Green-API webhook receives message (text or audio)
Voice → transcribed automatically
Main intelligent router agent selects one sub-agent/tool
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”
