The workflow automatically handles different message types, using Groq Vision for image analysis, Tavily for web searches, and Google Sheets for conversation memory. Self-hosted with n8n, the system took only a few hours to build and now runs autonomously across multiple channels.", "body_md": "I've been managing a Telegram channel for a while and kept spending time answering the same questions manually. So I built one n8n workflow that now does it for me automatically.\n\nThe cool thing is it works in any Telegram chat. You just change the system prompt and it adapts completely.\n\nWhen someone sends a message it figures out what to do on its own. If it's a photo — it downloads it and uses Groq Vision to actually see what's in the image. If the question needs current info — it searches the web via Tavily and answers with real data. For regular messages — it loads conversation history from Google Sheets and replies with full context like it remembers everything.\n\nTelegram Trigger → Parse Message → Should Skip → IF photo → Vision → Reply. Or needs search → Tavily → Reply. Otherwise → Load History → Groq LLM → Save → Reply.\n\nSame workflow, different prompt — completely different assistant. I use it in a tech channel, a shop, and a community chat. Each one feels like a separate bot but it's all one workflow.\n\nn8n self-hosted, Groq API, Tavily search, Google Sheets for memory, Telegram Bot API.\n\nTook a few hours to build. Now it just runs.\n\nI share more workflows like this in my Telegram channel [n8nAutomationHub](https://t.me/n8nAutomationHub) if you want to follow along.", "url": "https://wpnews.pro/news/i-built-a-universal-telegram-ai-assistant-with-n8n", "canonical_source": "https://dev.to/samsing1989/i-built-a-universal-telegram-ai-assistant-with-n8n-gh8", "published_at": "2026-06-11 22:10:37+00:00", "updated_at": "2026-06-11 22:43:03.574493+00:00", "lang": "en", "topics": ["ai-agents", "ai-tools", "ai-products", "natural-language-processing", "computer-vision"], "entities": ["n8n", "Groq", "Tavily", "Google Sheets", "Telegram Bot API", "n8nAutomationHub"], "alternates": {"html": "https://wpnews.pro/news/i-built-a-universal-telegram-ai-assistant-with-n8n", "markdown": "https://wpnews.pro/news/i-built-a-universal-telegram-ai-assistant-with-n8n.md", "text": "https://wpnews.pro/news/i-built-a-universal-telegram-ai-assistant-with-n8n.txt", "jsonld": "https://wpnews.pro/news/i-built-a-universal-telegram-ai-assistant-with-n8n.jsonld"}}
