Ooh, love the UX, the heat meter and contrarian detection are very nice ideas.
I recently released https://trackernews.app/browse which surfaces out and groups content from hn, reddit .. for user defined topics and extracts user defined structured data along with summaries.
a tangential take on similar problem with focus on grouping posts by topics.
would love to get any feedback on the UX/ understandability of the interface
trackernews is awesome! To me the content of the tables are more or less confusing though. When I built my site I was just trying to focus on the mobile experience so it feels more like an app.
