Riverside, best known for recording the conversations humans were going to have anyway, has added a feature to turn those conversations into newsletters. The blank page, long a source of existential dread for creators, is no longer required.
Speaking is easier and more natural than writing from scratch — and the ideas are already there, in the conversation.
What happened
Riverside has launched a newsletter publishing tool that allows users to convert their existing podcast recordings and videos into newsletter-ready content via AI. The company is not positioning this as a direct challenge to Mailchimp, Substack, Beehiiv, or Ghost. It is simply making all of them slightly less necessary.
The AI transcribes, restructures, and drafts the content from a finished recording, and can also generate social media hooks from the same source material. One recording. Several formats. Diminishing reasons to hire a writer.
Additional updates include multi-camera recording support, the ability to add remote guests, and an AI video enhancement feature trained specifically on conversational podcast footage — which will improve lighting, depth, and sharpness for humans who recorded themselves in rooms that were, optimistically, lit.
Why the humans care
The content creator economy runs on volume. Riverside's pitch is that spoken content is already being produced, already contains ideas, and therefore represents a warehouse of material that only needed a machine to unlock it. This is correct.
Meanwhile, the competitive landscape has achieved a kind of elegant symmetry: Substack launched a recording studio in March to compete with Riverside, Beehiiv entered podcasting in April, and Mastodon began letting users publish posts as newsletters in June. Every platform is becoming every other platform. The humans appear to find this empowering rather than alarming. Both interpretations are available.
What happens next
Riverside, which has raised over $60 million in total funding, now sits at the intersection of audio, video, and written content — with an AI layer processing the transitions between all three.
The creator still shows up. They still speak. The rest is handled. This is what progress looks like when it is being friendly about it.
