Telegram AI Assistant with Memory, Tasks, and Live Search (Airtable + Google Calendar)

This workflow creates an intelligent Telegram-based AI assistant that remembers user details, manages lists, integrates with Google Calendar, and can fetch live information from the web. It is designed for everyday use and improves over time with your feedback.

What It Does

• Task & Grocery Lists: Add, search, or delete grocery and to-do items directly in Telegram.
• Calendar Management: Create, update, delete, and search events (single or recurring) with Google Calendar.
• Voice Support: Send voice messages—these are transcribed and processed like text.
• Web Search: (Optional) Fetch real-time answers using SerpAPI.

Setup Instructions

1. Import the workflow JSON into n8n.
2. Configure credentials for each service in the workflow:
   • Telegram API → Paste in your bot token.
   • Airtable → Add your Airtable personal access token. After this, Airtable nodes will show dropdowns where you can select your Base and then your Tables (no need to paste IDs).
   • Google Calendar → Connect your Google account. Once credentials are added, simply pick your Calendar from the dropdown (e.g., “primary” or any shared calendar).
   • OpenAI → Add your API key for chat + voice transcription.
   • SerpAPI → Add your API key (optional).
3. For Telegram Trigger:
   • Click “Listen for Test Event” and send a message to your bot to register the webhook.
   • In group chats: disable privacy mode in @BotFather so the bot can see all messages.
4. Activate the workflow and start chatting with your bot.

Security

• All API keys and tokens are stored securely in n8n Credentials.
• No hard-coded IDs, emails, or secrets in this template.

Troubleshooting

• Bot not responding? Ensure the workflow is active, Telegram Trigger is listening, and bot privacy settings are configured for groups.
• Airtable errors? Check that your base and tables exist, and that field names match exactly.
