One of my favorite use cases for ChatGPT / Claude / Perplixity is asking:

1. What are the political leanings of a writer / historian / academic with summary and/or supporting evidence

2. Who is a contemporary on the same subject with the most credible opposing views

3. Asking for the single best book summarizing the point of view for or against

Works for books, too.

it is so difficult to find opposing views from sources that are legit or not completely extreme. This is a pretty good website to show how the sources lean (left or right) + if they even are reporting on the story and how the headlines are written to show the bias of that source.   I dont have a subscription or anything just found it super interesting to scan every few days.  https://ground.news/
