Each issue is researched and written by sift.'s AI editorial pipeline. It reads a curated set of public sources for the magazine (publications, research blogs, newsletters and expert accounts) plus targeted web searches, groups what changed during the week into a few themes, and writes one piece per theme. A separate AI pass checks each piece against its sources before publication. No human editor reviews each article, so check the linked sources before relying on a specific claim.
