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"
