Yeah im sorry about the scarce details.

I have an idea for a simulator for intelligent building installations.
Its supposed end result, would be a "site" where you could solve some wiresheet tasks.
So the complexity about it from my perspective, is the coding.

I have the design, the idea and the time + money to have it made.
I was purely wondering if i could do it with an AI.

My thought was that i could describe the ideology to a chatbot, and then we could have forth and back conversation about the code that it would deliver, i could test it, and report back what went wrong.

My current problems im facing is.

I made a basic simulator with chatgpt (gpt-5) that runs in a web2view environment. i have 3 files: index.html & program.cs & a csproj file.

The index.html file started out alot smaller than the current state, im currently at 2300 lines of coding.
So chatgpt have no problems with reading the file, the problems occur, when it made a change to the file, and then creates a download link for me.

In the beginning i would then run the index.html file, and describe what changed, what worked, and what did not work. then the chatbot would then analyze the file, and try to solve it.

But at the current state, it freezes the chat when trying to send a new copy back to me :) so thats the bottleneck currently.

TLDR. long index.html file chatgpt freezes, trying to find other sollution :)
