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.

How to set up

1. Clone this template into your n8n workspace.
2. Set up a WhatsApp Business API account (via Meta Business Suite or providers like Twilio, 360dialog, or MessageBird).
3. Configure the WhatsApp webhook to connect to your n8n instance.
4. Connect your Google accounts (Gmail, Calendar, Contacts, etc.).
5. Add your OpenAI API key in the Credentials section.
6. Test by sending a WhatsApp message like:
   • “Create a meeting tomorrow at 3pm”
   • “Add expense $50 for lunch”
   • “Draft a reply to that email from Steve”
   • “What’s on my calendar this week?”

• Adjust AI personality by modifying the system prompt in the OpenAI node.
• Control context memory to determine how much conversation history Jarvis remembers.
• Add automation rules like auto-categorizing expenses or auto-scheduling recurring meetings.
• Multi-language support by configuring OpenAI to respond in different languages.
