Simple AI Agent: Foundational Conversational Agent with Memory & Gmail Action Capability

Problem:

A business needed a lightweight but capable AI agent that could maintain conversation memory across a chat session and take real-world action by sending emails, without the complexity of a full multi-tool system, serving as a clean foundation for further agent development.

Solution:

Built a minimal n8n AI agent triggered by incoming chat messages, powered by OpenAI with Simple Memory enabled for session-level context retention, and equipped with a single Gmail tool allowing the agent to send emails directly as a conversation action, structured with clean tool output parsing for reliable response formatting.

Result:

Delivered a lean, production-ready AI agent foundation, capable of holding contextual conversations and executing real email actions, serving as a reusable base architecture that can be extended with additional tools and integrations as business needs grow.
