HR & IT Helpdesk AI Chatbot with Voice Transcription (RAG + Telegram)

This n8n workflow builds a Retrieval-Augmented Generation (RAG) helpdesk chatbot that answers HR and IT questions straight from your internal policy documents. Employees message the bot on Telegram using text or voice - audio messages are automatically transcribed before processing - and an AI Agent retrieves relevant answers from a PGVector knowledge base built with OpenAI embeddings, while Postgres-backed chat memory keeps context across the conversation. It's a scalable self-service support solution for HR and IT teams that want to cut down repetitive ticket volume while giving employees instant, accurate answers around the clock.
