this seems like an outstanding idea!
The cross-referencing between different corpora has actually been very helpful. I was able to find a typo in the notes to a US Code section through it and submitted it to the OLRC. They fixed it, so now I will forever be bragging about having fixed an error in the US Code haha
1) How much do you know about Policy Genius? Perhaps their trajectory could be instructive in what went well / wrong?
2) What do you think about adding a search for public equities? Type in AAPL, NVDA, etc.. and then UScodex delivers a code analysis that could surface relevant regulatory milestones / capture. If it works this could be a professional insights tool and/or "risk and compliance" software.
Good luck.
