Accepts text and voice (transcribed via **Mistral** by default) and uses an LLM agent that calls the **Web search** 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 **Web search** (Linkup) when web knowledge is needed and sends answers via **Telegram answer**.\n\n**How to use / Setup:**\n1. Create a Linkup account at [linkup.so](https://linkup.so) and get your **API Key**.\n2. In the **Web search** node, go to the \"Headers\" section and replace the placeholder API key with your actual key in the `Authorization` field.\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**Bold nodes to configure:** **Telegram Trigger**, **Web search**, **OpenAI Chat Model**, **Mistral transcribe**, **Myself?**\n\n*A template created by Guillaume Duvernay*"
