I fully realize the irony in that there's a high concentration of technical people on this site and therefore this may be a stupid place to ask this, but I bet you're have a better understanding of what's possible than me so here goes.
1. How far can you get using Claude, ChatGPT, etc. for helping code something from the ground up?
2. What other tools would you consider using to help you with this that can be used without coding?
You can probably get further with a no-code tool. The issues here are
- crafting the experience that stands out and can create network effect
- performance & cost, most of these tools are OK to start with, but will not scale with real-world usage
- if successful enough, you will have to rebuild from scratch with professional developers, low-code tools are not how these devs work, you'll also need to deal with the perf/cost issues at the same time
you could use a sheet of paper and draw an app sketch with coloured crayons
then fold it into a nice app shape and hold it together with some pretty sticky tape
