HeyNews reads a newsletter's back catalog, learns how its writer actually sounds, and drafts new issues in that voice. It monitors sources across RSS feeds, blogs, Reddit, and social media, scores relevance, and returns a publish-ready draft. The creator reviews and sends every issue; nothing auto-publishes. Native beehiiv API and Kit OAuth integrations, plus archive import from any other platform such as Substack and Ghost. Sold as self-serve plans and as done-for-you newsletters for companies.
