I co-founded a company in this space, although not focusing on summarization, and not targeted at normal citizens.
> I want to watch what congresses law/executive orders do. I don't want to read the laws, or how they work, or any of the details.
The real answer is "No you don't." Most congresses [1] pass a few hundred bills per year, and up to a thousand resolutions, and most of them are completely uninteresting to most people. On top of that, single bills can be omnibus monsters that touch 1000 subjects. That's not even touching executive orders (which are pretty minor), and regulations, which are not. There are usually a few hundred federal regulatory updates per week, which can be thousands of pages.
Jokes about government gridlock aside, the US is very big and the government does a _lot_, it's just that we're to the point where most of it is tweaking very specialized things. It's so much noise that the best way to be an informed citizen is, unfortunately, to find a few news sites you like, because it takes a large team to surface the stuff of interest to the general public.
At the risk of turning this into a news bashing political discussion, I think politico and thehill tend to have good content on congress, and are generally up front about political biases. A quick scan of those every other day will put you far ahead of most people.
All that said, both congress.gov and openstates.org (for state level stuff) offer searching and alerting, and every federal bill that's going anywhere does get a nice summary, although they are fairly verbose. But realistically you need a gatekeeper to sift through the chaff, because there's just too much happening.
