AI-Powered Calendar Assistant with PDF Q&A

This workflow combines AI-driven scheduling with document Q&A capabilities. It allows users to:

1. Automatically categorize and label emails using AI.
2. Chat with PDFs (like the Bitcoin Whitepaper) using GPT and Pinecone vector search.
3. Book calendar appointments via a conversational assistant that checks availability in Google Calendar and creates events seamlessly.
4. Notify users in Slack when conditions are met.

It’s a complete showcase of how n8n can integrate AI models, vector databases, email automation, and calendar APIs into a single intelligent assistant.
