Just plugging my service, https://mosaique.info/. It only uses an LLM to generate a short summary, and other ML algorithms structure the information (comments from officials and experts, classification...).
I'm currently working on a major overhaul to provide more holistic context around news by better surfacing less-discussed events.
I've built a similar product (https://www.mosaique.info), but it doesn't rely on LLMs (except for generating a very short summary). I think it offers a wider set of opinions and is much more exhaustive.
You won't be able to comment but it will show you what officials, companies and "experts" have said about a particular event. There are a bunch of other features too.
I'll add the sources to the comments in a future update. I need to come up with a good way to show them in the UI as some quotes can have dozens of sources (maybe some ranking and only showing the top 3).
