ChatGPT Skills are a new way to create reusable workflows inside ChatGPT. But if you already use Custom GPTs, should you keep building them or move those workflows into Skills?

In this video, I’ll show you exactly how ChatGPT Skills work, how to create your first Skill using Create with Chat, and how I turned one of my existing Custom GPT workflows into a reusable Skill.

We’ll cover:
→ What ChatGPT Skills actually are
→ ChatGPT Skills vs Custom GPTs
→ How to create a Skill without writing markdown
→ How to test, edit and share a Skill
→ How to convert the useful parts of a Custom GPT into a Skill
→ Why Skills are more reusable and portable
→ Skills vs Projects vs Plugins vs ChatGPT Work
→ Whether Custom GPTs are actually being replaced

By the end, you’ll have a simple framework for deciding which ChatGPT feature to use for your own workflows.
