AI-powered Gmail and Calendar assistant with Gemini chat interface

Disclaimer: This workflow uses Google Calendar and Gmail nodes which you will have to configure yourself Who’s it for Anyone who wants an AI-powered personal assistant that can handle Gmail and Google Calendar tasks through a simple webhook. This is useful for developers, small teams, and productivity enthusiasts who want to connect a chatbot (Discord, Telegram, WhatsApp, or custom frontends) to their email and calendar. How it works / What it does This workflow acts as a chat-based AI assistant. You send text requests through a webhook (e.g., from a chatbot), and the AI agent interprets them to take actions like: - 📧 Sending emails in Gmail - 📥 Reading and summarizing your emails - 📅 Checking your Google Calendar events - ✅ Checking your availability before booking - 📝 Creating new calendar events with Google Meet links - ✏️ Updating existing events - ⏰ Converting natural time expressions like “tomorrow at 3 PM” into exact timestamps The AI agent is powered by the Google Gemini Chat Model (or any LLM you choose) and follows strict guardrails: - Confirms actions before executing - Asks for clarification if details are missing - Prevents double-booking by checking availability How to set up 1. Import this workflow into n8n. 2. Set up credentials for: - Gmail (OAuth2) - Google Calendar (OAuth2) - AI provider (Gemini, OpenAI, Claude, etc.) 3. Configure the webhook node (/chat) as your chatbot endpoint. - You can connect it to Discord, WhatsApp, Telegram, or a frontend app. 4. Customize the AI Agent’s system prompt if you want to tweak tone or rules. 5. Deploy and start sending messages like: - “Check my emails from today” - “Schedule a meeting with John tomorrow at 3 PM” - “Email my team about the deadline extension” Requirements - n8n installed and running (cloud or self-hosted) - Gmail and Google Calendar accounts with API access - API key for your chosen AI provider - Webhook Chatbot interface How to customize - Swap Google Gemini with another LLM node (e.g., OpenAI GPT or Anthropic Claude). - Add more tools (e.g., Slack, Notion, Trello) to extend capabilities. - Adjust memory length in the Simple Memory node. - Modify sticky notes with instructions tailored to your use case. Disclaimer - This workflow uses the community webhook entry point, so it is best suited for self-hosted n8n instances. - Do not hardcode API keys or sensitive credentials. Always use n8n’s Credentials system. Other Details Thanks for viewing this automation!
