How this works
This workflow creates a Telegram bot that acts as an intelligent personal assistant, letting users send voice messages or questions and receive instant, accurate replies drawn from both AI knowledge and their own PDF documents. It handles voice-to-text conversion, performs retrieval-augmented searches across uploaded files, and pulls live data from Google Workspace tools when needed. The core step is the Gemini-powered reasoning node that decides whether to answer directly, consult the document store, or call external tools.
Use it when you need a single conversational entry point to your documents and Google services; avoid it for high-volume customer support or when strict data residency rules apply. A common variation replaces the RAG step with live web search or adds scheduled daily briefings pulled from Sheets.
About this workflow
This comprehensive workflow bundle is designed as a powerful starter kit, enabling you to build a multi-functional AI assistant on Telegram. It seamlessly integrates AI-powered voice interactions, an intelligent PDF document search using a Retrieval-Augmented Generation (RAG)…
