I've only been lucky enough to find one opportunity in my entire twenty-seven year career to write something novel and new. Most of the time we're reinventing the wheel. What separates the winners from the losers is whether or not it's your wheel.

I don't know, you don't have to invent cosmopolitan libc to qualify as new, but my bar is higher than another LLM chat app.

Then again, maybe OP's app will have some new twist that will revolutionise everything.
