Workflow automation has always fascinated me.
I have spent a lot of time exploring how people automate their work and boost productivity.
Recently, OpenAI’s ChatGPT Agent Builder caught my attention, and honestly, it feels like a major shift is happening in the world of automation.
Let’s break down what’s changing and why it matters.
The Old Way: n8n and Zapier
If you have ever tried to automate tasks, you probably know about n8n and Zapier. These platforms let you connect apps and set up workflows to handle things like posting on social media, updating spreadsheets, or sending reminders.
The appeal is clear: you do not need to be a programmer to get started.
But there are some real challenges.
The interfaces can get complicated, especially as your workflows grow.
Customizing things beyond the basics often means reading through documentation or paying for extra features.
