If you're looking for a replacement for Artifact (and for news apps in general), you should check out https://tailor.news

It aggregates the news from thousands of newspapers, youtube channels and podcasts, then serves you a summarized digestible version, as a feed and as a personalized podcast, using LLM models.

You can also ask to clarify or explain the news, and there's a new function to ask if an article's claims are supported by other sources, to avoid reading biased or opinionated information.
