None. You gotta read multiple sources and snort an ounce of salt. I don’t use it, but if you don’t wanna manually look it up, check out apps/sites like ground news. It can help gather a bunch of articles from a bunch of sites. It shows the bias, leaning, and factuality. It even has a Blindspot option for sites you don’t usually use. I am not willing to pay lol so I do it manually.
Al Jazeera is surprisingly decent despite its owner being the Qatari government.
