Overview

🧠 Telegram Search Assistant — Tavily + AI/ML API

This n8n workflow lets users ask questions in Telegram and receive concise, fact-based answers.
It performs a web search with Tavily, then uses AIMLAPI (GPT-5) to summarize results into a clear 3–4 sentence reply.
The flow ensures grounded, non-hallucinated answers.

  • ⌨️ Typing indicator for better UX
  • 🔎 Web search with Tavily (JSON results)

  • 📤 Replies in the same chat/thread
  • ✅ Guardrails against hallucinations
