Building an AI agent isn’t complicated.

You need three things: a brain (chat model), a memory (buffer), and a testable interface.

I use GPT-4o for the logic, window buffer for memory, and N8N’s chat interface to test—before deploying anywhere else.

Simple system. Predictable output. Scalable automation.
