I'd recommend you abandon this idea. What attracts most people to YC is money, connections, and advice. It doesn't sound like you're in a position to offer these things.

If you need help figuring out to work on, Startup School is a good option. Reading Paul Graham's essays on ideas should help. His advice is not all applicable to people outside his bubble but his advice on ideas is excellent.

Choosing the idea is the most critical thing you will do. The difference between an idea that seems good and one that is actually good can be very difficult to determine. Sometimes the easiest thing to do is to launch multiple projects and see which gets traction. In any case, the ability to iterate on multiple projects and then multiple versions is a hugely powerful ability.

I'd recommend you focus on solving some problems you have experienced personally. Want a GIF meme generator for your Discord channel? Do that. Or anything regardless of how trivial it is but just focus on making it grow. Worry about the financial aspects after you have learned how to make something succeed. Maybe you will find that your project can't be easily monetized but at least you will learn what market success feels like for the next project. Or you can decide to do only things that might have a good financial outcome, that could work too, but it still would be very good to solve a problem you have experienced.
