The big difference is that Copilot generates real, functioning code based off past implementations of real, functioning code. A no-code tool like Webflow is an entirely different product all together. The ML transformers powering Copilot are the secret sauce here, that technology just literally did not exist when Java and UML were all the rage.

I'd encourage anyone who hasn't tried it to give Copilot a try. There really has never been anything like it in my memory, and while I totally agree there have been dozens of efforts to allow non-technical people to generate code, I think Copilot may be on to something very special.
