Voice-Activated Multi-Agent Demo for Vagent.io with Notion & Google Calendar

This n8n workflow enables a lightweight voice interface via the Vagent app, where users record messages that are transcribed and sent to a webhook alongside a session ID. A main AI agent acts as a router, interpreting the input using stored chat history to select appropriate sub-agent tools—essentially sub-workflows—for tasks like Notion database management or Google Calendar scheduling.

Sub-agents maintain separate chat memories (suffixed session IDs) for clear separation of concerns. They process raw input, call HTTP requests for actions (e.g., creating Notion pages or calendar events), format results in Markdown with indentation for drafts, and return concise prompts to avoid misinterpretation by the main agent.

The main agent compiles the output, separating drafts from spoken responses, and sends a split spoken/text version back via webhook. Benefits include hands-free productivity for teams, seamless integration of custom AI agents with existing tools, and scalable multi-agent architecture. Use cases: Quick task delegation via voice (e.g., 'Schedule meeting with team'), Notion content creation from speech, or calendar management without typing—ideal for busy professionals or organizations.
