Riverside, the video and podcast recording platform, announced in 2026 that it is expanding into newsletter publishing, giving users the ability to convert their recordings into newsletters using AI and send them directly from within the app.
The feature is designed to reduce the effort required for creators to repurpose spoken content into written form. Rather than competing head-on with dedicated newsletter platforms, Riverside is positioning the tool as a natural extension of content its users are already producing. Users can also write and send newsletters from scratch without using the AI conversion feature.
Nadav Keyson, Riverside’s co-founder and CEO, explained the rationale: “Substack and Beehiiv start you at a blank page. But our creators and business customers are already producing rich, information-dense spoken content on Riverside. For most people, speaking is easier and more natural than writing from scratch, and the ideas are already there, in the conversation. So instead of asking them to start over in a separate tool, we help them turn a recording they’ve already made into newsletter-ready content with far less effort.”
Alongside the newsletter feature, Riverside is updating its recording suite to support multi-camera setups and the ability to add remote guests to recordings. New AI tools include a feature that drafts a first cut of a recording immediately after it finishes, an assistant that generates hooks and content for social media platforms, and a video enhancement tool trained on conversational video podcasts that the company says can improve lighting, depth, and sharpness.
Riverside, which has raised over $60 million in funding, is not alone in pursuing cross-format expansion. Substack launched a built-in recording studio in March, Beehiiv moved into podcasting in April, and Mastodon announced in June that it would allow users to publish posts as newsletters — a pattern that suggests platforms across the media landscape are broadening beyond their original formats.
