Who's it for
This template is designed for anyone who wants to use WhatsApp as a personal AI assistant hub. If you often juggle tasks, emails, calendars, and expenses across multiple tools, this workflow consolidates everything into one seamless AI-powered agent accessible right from your most-used messaging app.
What it does
Jarvis listens to your WhatsApp messages (text or audio) and processes them with OpenAI. Based on your request, it can:
- ✅ Manage tasks (create, complete, or delete)
- 📅 Handle calendar events (schedule, reschedule, or check availability)
- 📧 Send, draft, or fetch emails with Gmail
- 👥 Retrieve Google Contacts
- 💵 Log and track expenses
- 🎤 Process voice notes and respond intelligently
All responses are returned directly to WhatsApp, giving you a unified command center that works on any device.

- Configure the WhatsApp webhook to connect to your n8n instance.
- Connect your Google accounts (Gmail, Calendar, Contacts, etc.).
