Accepts text and voice (transcribed via **Mistral** by default) and uses an LLM agent that calls the **Query knowledge base** tool.\n\n**How it works (short)**:\n1.  **Telegram Trigger** → Detects text or voice via **Message Router**.\n2.  Voice: **Get Audio File** → **Mistral transcribe** → prepare text.\n3.  **AI Agent** calls **Query knowledge base** (Lookio) when domain knowledge is needed and sends answers via **Telegram answer**.\n\n**How to use / Setup**:\n1.  Create a Lookio assistant; get **API Key** and **Assistant ID**.\n2.  In **Query knowledge base**, replace `<your-lookio-api-key>` and `<your-assistant-id>`.\n3.  Add credentials: **Telegram API**, **OpenAI (or LLM)**, **Mistral Cloud**.\n4.  (Optional) Edit **Myself?** to set your Telegram username for private testing or delete it to make the bot public.\n5.  Activate the workflow and message your bot in Telegram.\n\n\n**Bold nodes to configure:** **Telegram Trigger**, **Query knowledge base**, **OpenAI Chat Model**, **Mistral transcribe**, **Myself?**\n\n*A template created by Guillaume Duvernay*\n"
