Send it a text or a voice message and it will transcribe voice with OpenAI, understand your request, then use its tools to read your recent emails, check your Google Calendar, read your Notion tasks and contacts, and draft and send an email for you \u2014 always after you approve it on Telegram. It keeps a short memory of the conversation so you can ask follow-up questions.\n\n## Setup\n1. Telegram: select your bot credential on the 3 Telegram nodes (Trigger, Approval, Reply).\n2. OpenAI: select the \"OpenAi account\" credential on the Chat model and the Transcribe node.\n3. Gmail: select your Gmail credential on the two email tools.\n4. Google Calendar: select your credential on the calendar tool.\n5. Notion: select your credential on the two Notion tools, then pick your Tasks database and your Contacts database in the dropdowns.\n6. Open the Configuration node to set the assistant name, model, languages and memory window.\n\n## Requirements\n- An n8n instance (cloud or self-hosted). All nodes are native, no community node required.\n- A Telegram bot token (via @BotFather).\n- OpenAI, Gmail, Google Calendar and Notion credentials.\n\n## Customization\n- Change the model in Configuration (e.g. gpt-5.4-mini for lower cost).\n- Add or remove tools on the Nova agent.\n- Edit Nova personality in the agent System Message.\n- The email tool is gated by a Telegram approval \u2014 you can switch it to a single button or a form.\n\nNeed help customizing?\nContact me for consulting and support : [Linkedin](https://www.linkedin.com/in/doctor-firass/)\n\n# MY NEW YOUTUBE CHANNEL\n\ud83d\udc49 [Subscribe to my new YouTube channel](https://www.youtube.com/@DrFiras_AI).
