TechCrunch: Podcasting platform Riverside enters newsletter publishing

Riverside, best known as a remote recording platform for podcasters and video creators, launched a newsletter feature on June 30, 2026. The tool uses AI to convert existing recordings into newsletter-ready content, which creators can then send directly from within Riverside without exporting to a separate email platform.

The feature works in both directions: AI drafts a first cut from the recording immediately after it finishes, and creators can also write newsletters from scratch without AI assistance. Additional AI capabilities include social media hook generation and automatic content repurposing for different formats.

For content creators whose primary output is spoken—podcasters, video essayists, interview show hosts—the feature addresses a gap that has existed for some time. The ideas are in the recording; getting them into written form for an email audience requires either hiring a writer or setting aside time to write from scratch. Riverside’s CEO Nadav Keyson frames it as removing that friction: “speaking is easier and more natural than writing from scratch.”

The move puts Riverside in competition with Substack, Beehiiv, and Mailchimp for creator newsletters, though Riverside’s angle is repurposing rather than original written content. For writers and journalists who also produce audio or video, this means the relationship between spoken and written content is getting structurally simpler to manage within a single platform.
