Show HN: AI News Agg tracks trending AI stories across 48 sources

A developer built AI News Agg, a site that aggregates AI-only news and announcements from 48 selected sources spanning mainstream media, tech publications, bloggers, and company websites. A story covered by three or more of these outlets is flagged as trending and placed at the top of the site. Users can also receive email alerts when a new story starts trending, plus an optional personalized daily AI brief on the subjects or entities they want to follow.
