I've been working on the data processing side of legal text with https://www.wordstodata.com/

Your work seems more targeted at tracking the real world impact of the bill rather than the changes it makes to the legal code, but a feature on my roadmap is having bill data also be easily linkable to the votes of politicians so you can track the effect politicians have on the legal code per member. Do you plan to build a member tracker on top of this as well? I think it would be super cool to be able to tie news events to a track record of votes by member of congress.

Yes! If you go to the engage tab you can look up some reps and the policies they're sponsoring but I plan on giving impact scores and where certain reps are focusing their time in the future.
