Starts on a Google Drive event

On new Google Drive PDFs, embeds content into Pinecone and answers chat questions with an OpenAI RAG agent.

Google Drive Document Q&A API

Loads Google Drive documents into a Qdrant vector store and answers questions via webhook using OpenAI retrieval QA.

On a webhook, an OpenAI RAG agent over Qdrant answers questions, checks Google Calendar, and replies; indexes Google Drive docs.

On webhook input, an OpenAI agent answers from a Qdrant store of Google Drive docs, books Google Calendar events, and replies on Telegram.
