Jarvis is a powerful multi-agent productivity assistant built in n8n. It works directly from Telegram and can understand both text messages and voice notes. The workflow uses a main Jarvis Manager Agent to understand the user's request and route it to the correct specialist agent, such as Gmail, Calendar, Google Tasks, Finance, or Contacts. It can send and reply to emails, manage calendar events, create and complete tasks, track expenses in Google Sheets, search contacts, and respond back to the user in Telegram. This template is useful for anyone who wants a personal AI assistant that can manage daily productivity tasks from one simple chat interface.
