Substack is becoming app-like
Substack’s product is shifting from email-first to a richer, in-app experience where creators publish live video, episodes and subscriber chat, meaning discovery and consumption are moving inside the mobile app itself. (writebuildscale.substack.com) Creators are explicitly using features like “Watch now” and integrated media formats, which changes the baseline for what users expect from a briefing product’s native consumption and discovery.

Substack used to be the place where a writer hit send and a story landed in your inbox. In 2026, Substack’s own app page sells something wider: “video, podcasts, and writing,” plus subscriber chats inside an iPhone and Android app. (substack.com) The product now has a Home feed, not just an inbox. Substack’s support guide says that Home shows notes, recommendations, conversations, and a reading queue, which means discovery is happening inside Substack before email ever gets opened. (support.substack.com) That is a different habit from the old newsletter model. An email newsletter works like mail arriving at your house, while a Home feed works like walking into a mall where Substack decides which storefronts you pass first. (support.substack.com) Substack has also turned live video into a built-in publishing format. Its live video guide says creators can stream from the app, send instant email and push notifications, and choose whether a stream is open to everyone, all subscribers, or paid subscribers only. (support.substack.com) The company is wiring chat directly into that video. Substack says any app user can comment in live video chat on public streams, and creators can lock access down to subscribers or paying members when they want a smaller room. (support.substack.com) It is also pushing those videos into the discovery layer. In a February 6, 2025 post, the Substack team said live video previews now appear in the Notes feed and can be restacked by other users, which turns a broadcast into something that can spread through the network like a social post. (substack.com) The app itself now describes separate behaviors with separate tabs. Substack’s App Store listing says users can read, watch, chat, and publish from one app, which is much closer to a media platform like YouTube or Patreon than to a plain email tool like Mailchimp. (apps.apple.com) Substack’s own features page makes that strategy explicit. The company says it offers newsletter publishing, podcast hosting, native video, community tools, paid subscriptions, Notes, recommendations, and category leaderboards in one system. (substack.com) The company kept adding more recording infrastructure in March 2026. TechCrunch reported that Substack launched a built-in recording studio for solo videos and two-guest conversations, with auto-generated clips and thumbnails, so creators no longer need a separate stack of video tools just to make something watchable in the app. (techcrunch.com) Then it went past the phone. Deadline reported on January 22, 2026 that Substack launched a beta television app for Apple TV and Google TV, giving long-form videos and livestreams a place on the biggest screen in the house. (deadline.com) So the shift is not “writers can also upload video.” The shift is that Substack now has a feed, chat, livestreams, clips, recommendations, mobile viewing, and even a television app, which means the company is trying to own discovery, consumption, and community instead of just the email delivery step.
