I was using Bing Chat to create code then test it. I then fed the errors to Claude.ai which gave the fixes. I then told Bing Chat the fixes from Claude.ai, it amended the code and I retested and fed the errors to Claude.ai... etc... until it worked. Some iterations took 10 loops. Other times just 3. If 'I' wasn't sure what I wanted it might take 30 iterations and still not be the right answer.

Why is there no automated way to iterate code with AI like this?

I can't do this manually now as the Bing Chat limit is now 4k characters (and now 2K for Copilot) and it is too low to achieve this.

But once I had the idea I didn't need to know how to code it myself. I might need to create free accounts with several APIs.

This gives a ‘similar feel’ for how code was developed but this time developing a formula:
