I like the styling, it's really slick. I also like that you enable me to use the tool online without signing up. I was curious about how you're supporting this, and paying for inference, but I see now that you haven't really wired up anything. When I try to generate my 1pager, it returns a placeholder.

I'm not a fan of this framing. Messy has negative connotations, so it's not clear why you're insulting me when we just met. ;)
The wizard:
There's a bit of duplication, since you have "Tell the agent..." as well as "Tell me...", both conveying the same information.
I can jump through steps without competing prior ones. Isn't that going to cause a problem?
It's hard to truly evaluate this further without seeing it in action. As other authors have said, many agents already support Plan Mode, so it it's important for you to distinguish yourself from that.
