I believe this is a fantastic idea, even if only because I literally was ideating on the same lines just last week.
I think there were some usability issues, but overall, solid stuff.
I think if I were you, I would focus on the UX of legislative bill analysis rather than the LLM side of it, but that's just me.
Happy to talk more about this if you're interested. I have a lot of ideas around this. And see this kind of setup as really important, and benefitial.
Hey thanks for the quick feedback, I'm updating the UX atm and you can hit me up on twitter: https://x.com/jolerapidee
