RAG chatbot over Google Drive knowledge base

n8n · complex · 50 nodes

Telegram Wait Automate Webhook is an n8n automation template that builds an AI-powered RAG chatbot over documents stored in Google Drive, using Gemini and GPT-4o-mini models. The workflow loads files from a specified Google Drive folder, splits content into tokens, generates embeddings with text-embeddings-3-large, and stores vectors in a Qdrant collection. When a question arrives via Telegram or Webhook, the AI Agent retrieves relevant chunks and composes a response using Window Buffer Memory for conversation context. Outdated vectors can be removed from Qdrant by file ID, keeping the knowledge base in sync with Drive. Ideal for teams that need a private document assistant without exposing files to third-party services. Trigger: manual. Integrations: Google Docs, Google Drive, Telegram. Nodes: 50.
